Normal POV

(Hospital)

"Wahhhhhh" a baby cry sound was heard in a room of a hospital.

A baby boy was born. His father was holding him gently with happiness, he tried to stop letting his emotion control him. But as he imagined about the family's happy life when the baby boy joined the family, tears began to gather in his eyes. Once the first tear broke free, the rest followed in an unbroken stream. The baby's father, Mr Hyoudou was crying with joy. His dream to have a boy came into fruition. He looked at the baby, noticing his eyes didn't move together smoothly. He smiled warmly as he knew that it was a normal phenomenon. He then turned to his wife, Mrs Hyoudou who was lying on the bed.

"What should we call our wonder son? How about….. Issei? Hyoudou Issei!" Mr Hyoudou said with a bright smile.

"Yes! Let's call him Issei. My son…" Mrs Hyoudou said while holding tears in her eyes. She used all her energy for her to sit properly, holding Issei from her husband's hand. She looked at Issei, touching his skin which was wonderfully soft. She couldn't help but giggled of Issei's cuteness. After having a moment of the first "mother and son" time, a girl with a shapely figure came into the room. Her eyes was brown same as her hair, making the nurses and doctors stunned by her beauty. She went to the side of Mrs Hyoudou's bed, attracted by the wonderfulness of the baby.

"So Dad, is that my brother?" the girl called Hyoudou Yukina asked with an exciting tone.

"Yes dear, this is your brother—Hyoudou Issei, the newest member of the Hyoudou family!" Mr Hyoudou shouted while hugging his daughter. Yukina was embarrassed by the sudden hug from her father, but she was also happy as she finally had a brother to play with.

Suddenly, the hospital was shaking. Mr Hyoudou and Mrs Hyoudou looked around, the doctor and the nurse inside the room were gone. The room was filled with darkness, close to block their vision. Yukina was trembling by the situation, she ran to the door trying to escape, but the door was locked from the outside which was supposed to be impossible. Mr Hyoudou came to her side, holding her head comforting her as much as he can. However, he was also scared as he never faced situations like this. Mrs Hyoudou who was holding Issei panicked as she didn't expect such situation to happen as well. Issei was probably shocked as he cried loudly and making everyone felt worried.

A tall man with a nice figure appeared out of nowhere. He was holding a yellow glowing spear making everyone stared at him. Mr Hyoudou sensed that he was a threat, he looked at Yukina who was still trembling, holding her shoulders with a worried face.

"Yukina! Get back! Hold Issei so he won't be in danger! Hurry!" Mr Hyoudou shouted towards Yukina, Yukina nodded and rushed to Mrs Hyoudou's side, holding Issei tightly to protect him.

"Who are you? Why are you here?" Mr Hyoudou asked the man with a trembling tone. He could tell that the man standing in front of him was a powerful man. However, in order to protect his family, he stood up to confront the man himself. The man scratched his cheek, explained with an annoyed tone.

"My name is Kokabiel. A Fallen Angel from the Bible. I'm one of the leaders of the Fallen Angel, and I'm here to kill your son. Your son held a sacred gear, which was harmful to the supernatural beings like us. If you are willing to step away from this, I will spar your life. However, if you refuse, I will make your body into thousands of pieces and throw it away to feed the hungry wolf in my dungeon."

"There is no way I will let you kill my son! I will now fight you for the peace of my family!" Mr Hyoudou said with determination. He tightened his fist and pointed towards to Kokabiel. However, Kokabiel had no sign of blocking his punch. Mr Hyoudou grinned as he thought that he can protect his family, Kokabiel threw a spear passing through Mr Hyoudou's stomach. He then crossed his arms and looked at Mrs Hyoudou. Blood spread everywhere making Mrs Hyoudou cried in pain. She couldn't thought that her husband was killed without any mercy from the enemy. She was both angry and sad that she stood up from her bed trying avenge her husband. She stood up while gritting her teeth as the pain after the delivery still existed. Staring Kokabiel with a scary face, she screamed

"I DON'T KNOW WHO YOU ARE OR WHATEVER THE HELL ARE YOU FROM, YOU KILLED MY HUSBAND AND I'M GOING TO AVENGE HIM!"

Kokabiel sighed as he completely ignored her. He walked towards Issei while getting blocked by the human mother. Tilted from her action, he stabbed another yellow spear to her head, making her fall down. This time it was more serious as her face were no longer recognizable. Only blood was covering her face making Yukina scared more then ever. She was traumatized by the whole scene, and her body couldn't stop shaking as she just witnessed both of her parents getting killed by a powerful man. As Kokabiel got closer, Yukina walked back step by step until she felt she was blocked by the wall. She hold her brother more even tightly wanting to protect him, but that's nothing she can do. Eager for assistance, she kept praying for God to help her even though she was never a Christian. However, none of that work. No one came and save her and her brother.

"Just give up. This is your fate. Your fate is to get killed because of your brother. Curse him as he lead the death of yours." Kokabiel stated making Yukina fell in apart.

Kokabiel created another spear, pointed towards Yukina. Yukina finally gave up hope as she looked at him emotionlessly. However, the fact that she still hold Issei tightly made him feel irritated. Issei was calmed by the warmth of the hug, but Yukina was scared as she knew that both of them will die. He threw his spear towards Yukina. Realizing this was fate, Yukina closed her eyes slowly waiting for her death. Unexpectedly, a loli girl appeared suddenly causing the spear to stop on its own.

"Who are you? WHY YOU ARE HERE STOPPING MY PLAN?" Kokabiel shouted. However, he started to tremble after sensing the girl's aura. Her aura was unexpectedly high, he sensed their were no limits of her energy.

"I'm Ophis, Ouroboros Dragon. The Dragon Of Infinity." Ophis introduced herself with a monotone making Kokabiel fall on the ground shaking with fear.

"Ophis….. No please don't kill me!" Kokabiel begged for mercy making Ophis sighed.

"I'm just going to let you go. If you dare to harm this baby I will kill you." Ophis said.

Kokabiel teleported himself away while having fear in his eyes. Ophis turned and looked at Yukina. Yukina was shocked by the events happening right now. She didn't know what the hell was going on. Her parents were killed by a so-called Fallen Angel. She almost got killed but a loli girl called Ophis rescued her. Ophis turned herself towards Yukina and walked to her side slowly. Yukina was unsure of Ophis next action making her shaking again, but not as much when Kokabiel trying to kill her.

"I will not harm you. After all the reason I'm here is to fuse myself into this baby's Sacred Gear." Ophis said while patting Yukina's head. Yukina felt a little bit relived but was confused about what Ophis said.

"Umm… What is a Sacred Gear?" Yukina asked.

"Before I explain, Do you believe God from the Bible?" Ophis asked.

"Not before this." Yukina replied.

"Well, God is real. Fallen Angels, Devils, Angels from the Bible are all real. Everything related about them are real." Ophis said making Yukina blew away.

"WHAT?" Yukina shouted.

"Wah….." Baby Issei cried as Yukina shouted too loudly.

"Don't scream that loud. He will cry. I will cast a sleep spell of him so I can continue my explanation." Ophis said as she took out her finger and she placed on Issei's forehead. After that, Issei stopped crying and slept.

"Ok let me continue. Sacred Gear is created by the God of the Bible. He created as part of his system to enact miracles on Earth. He also wanted to help human to confront with the supernatural such as Devils. Your brother is one of the Sacred Gear possessors. If the Sacred Gear is removed, the possessors will die." Ophis explained making Yukina to understand more about supernatural.

"So, I heard that you are the "Dragon God" right? Are you the strongest in this world?" Yukina asked.

"Yes. I'm the strongest existence existed in this world. In fact, the universe. However, one more existence could compete with me. He is the Apocalypse Dragon, Great Red. He is also the Dragon of Dreams, similar to Infinity." Ophis said.

"Ok I learnt enough. Then why are you here?" Yukina asked as she really wanted to know why the strongest existence in the universe came here to save her brother.

"Originally, I wanted to fight Great Red who was residing in the "Dimension Gap". The "Dimension Gap" was my original home before Great Red came and forced me to leave. I came to Earth to gather reinforcements to help me fight him, However it didn't work out. Instead, they used my power to cause destructions everywhere. I felt guilty and I wanted to redeem myself by sealing myself. The best will be residing in a Sacred Gear and I will be giving my power to the kindest person in the world. Your brother will be the one I'm choosing so that's why I came here to save your brother." Ophis explained making Yukina shocked.

Ophis stood up prepare to leave.

"Wait! Where are you going?" Yukina asked feeling worried about being alone.

"I will be returning. I will meet you again when he was 6 years old. At that time, he was probably able to wield my power." Ophis said and she teleported away.

Yukina found herself back to her home again. She was shocked that her home had added accessories for a baby, and even a huge bed for the baby to rest in. She then put Issei on the bed. Without knowing what to do next, she sat there and calm down for a while.

(6 Years Later)

(Hyoudou Residence)

"Nee-san! Play with me! Hide-And-Seek!" Issei shouted to Yukina who was doing household chores.

Issei was a cute boy around 1.25m with brown eyes and brown hair same as his sister. He was wearing a red t-shirt and a yellow shorts. He ran towards Yukina who was holding a vacuum cleaner. Yukina put down her vacuum cleaner and patted Issei's head.

"Issei, what did I tell you? Nee-san needs to finish the household chores first right? Issei be patient ok?" Yukina said making Issei felt sad. Tears started to flow from Issei's eyes.

"Don't worry I will play with you. After 2 minutes okay?" Yukina said making Issei wipe his eyes, and he looked at Yukina with a happy face.

"Promise?" Issei asked.

"Of course my little brother." Yukina smiled.

"Yay! Nee-san I love you!" Issei hugged her tightly.

Suddenly, a girl appeared at the back of Issei. Yukina looked at that girl, she was shocked.

A loli girl.

The same girl she saw six years ago, the day of her parents' death.

"Ophis….?" Yukina asked hoping for the answer.

"Yeah is me. I forgot to ask your name six years ago. What is your name?" Ophis asked,

"My name is Hyoudou Yukina, and this one here is my brother that you are looking for – Hyoudou Issei." Yukina placed her hands around Issei and introduce him to Ophis.

"Hello Ophis-san! I'm Hyoudou Issei. Please take care of me." Issei said bowing to Ophis.

"Issei. Nice to meet you. My name is Ophis, Ouroboros Dragon. The Dragon Of Infinity." Ophis said with a monotone again.

"Ugh… this is the same tone that you used six years ago. WAIT! That's not what I'm going to ask you. Why you are still the girl six years ago?" Yukina asked with a confused voice.

"I'm ageless. I can change whoever I want. For example, I can change myself into a 100 years old woman, a baby, teenager as well." Ophis said while changing her appearance.

She changed to an oldwoman immediately. The woman that she changed was a 100 years old woman. She looks like a reclusive character who was homeless. Her face was time chiselled and weather beaten.

"Wow" Yukina said with amazement.

Ophis turned back to a loli girl. Yukina looked at Issei who was shocked just like her. Issei then raised his head to look at Yukina, making her smile as the warmth that Issei's smile deliver made her feel reassured.

"Now, I will summon his Sacred Gear and fuse myself in it" Ophis said raising her hand ready to seal herself inside Issei's Sacred Gear. She started to gather energy and summon Issei's sacred gear.

(Mile away)

Sirzechs Lucifer, one of the Youdai Maou felt irregular presence nearby.

"…. That presence…! Is that ..Ophis?!" Sirzechs thought to himself. He was shocked that Ophis was nearby, and she was in an ordinary human world.

"If her objective is to still find people to kill Great Red…. That's bad! I need to stop her now!" Sirzechs summoned a magic circle trying to teleport himself to Ophis' location.

(Hyoudou Residence)

Issei's Sacred Gear was forcefully summoned by Ophis. It was a normal Twice Critical. However, it was a dragon-type Sacred Gear which able Ophis to seal herself inside.

"Now, I will put myself inside the Sacred Gear" Ophis began to gather enormous aura. She closed her eyes and raised both of her hands, mumming something that even Yukina didn't understand.

At the same time, Yukina noticed that a magic circle appeared on the ground. However, it was red and it showed the symbol of "House Of Gremory". A crimson-haired man appeared and faced Ophis.

"Ophis! That's enough! I will stop you Ophis!" Sirzechs shouted while holding a sphere of Power of Destruction.

"Sirzechs….. You cannot stop me. I will put myself inside the Sacred Gear." Ophis said continuing to put her energy inside the Twice Critical.

"Stop Ophis! Issei cannot handle this sort of power! He will die!" Yukina screamed as she didn't want to lose her only brother. Issei meant the world to her since her parents were killed. She raised him, fed him, took care of him all by herself. She couldn't leave Issei to face the supernatural on such a young age. Not willing to lose Issei, she stood in front of Ophis trying to stop her.

"Relax Yukina, he won't die. He was the only one who can wield my power while being kind." Ophis said making Sirzechs more angry.

"Stop it Ophis! You will just bring catastrophe to this world! I will now stop you so no more innocent people will be involved again!" Sirzechs shouted with determination. He put his hands on Yukina's shoulder and pulled her back.

He threw an orb made of Power of Destruction towards Ophis. However, Ophis' power was immortal that it was impossible for her to get hurt. The orb with great power that Sirzechs sent vanished when it almost reached Ophis. Sirzechs then made more bigger and powerful orbs and threw them towards Ophis, while Ophis was focusing her energy into Issei's Sacred Gear. Issei felt there was a powerful energy flowing inside his arm as Ophis continued to send her immortal power towards Issei. Issei's Twice Critical started to be bright, making Sirzechs suffer as it's a devil's weakness. Issei and Yukina had to turn around and close their eyes as it made them uncomfortable as well.

After the light started to become dimmer, Issei and Yukina opened their eyes and Sirzechs stopped to become painful. Issei then looked at his left arm, Although the Sacred Gear was still in the same shape, the color was different. The gear glowed in a rainbow color except the Jewel which remained green, making Sirzechs and Yukina shocked about the transformation of it.

[The new Sacred Gear is now called Infinity Critical. In the current state, Issei was able to unleash one millionth of my original power. But with more and more training, he could be able to have full access of my power, being the next Dragon God of Infinity.] The jewel glowed and a familiar voice could be heard. It was Ophis'.

"No way…. Issei….." Yukina said while being shocked about Issei's new strength.

"Infinity Dragon Emperor, Hyoudou Issei….. The wielder of the newest and the strongest High-tier Longinus – Infinity Critical…. I can already sensed this child's potential and he was holding the fate of this universe at such a young age." Sirzechs said feeling scared about Issei. After all, no one had been able to access Ophis' power.

"Ophis! Ophis!" Issei shouted looking at his Infinity Critical.

[Issei, you are my partner starting from today. You need to train yourself to become strong to protect your sister and the ones you love. Don't worry I will help you train.] The green jewel started to glow again as Ophis said to Issei.

"Ophis! Please don't! My brother is still young! I can't make him do that!" Yukina shouted worrying about her very own brother.

Sirzechs turned to Yukina with shock as he didn't expect this beautiful young woman was Issei's big sister.

"How rude I am to not introduce myself beforehand. As you know about the supernatural, there were no reason to hide my identity. My name is Sirzechs Lucifer. I'm a pure-blooded devil from the House Of Gremory, and one of the Four Great Devil Kings. As a Devil, we had a life-span of ten thousand years. Our strength and power surpassed normal human kind, That's why I was able to shoot those black sphere. The sphere was created by Power of Destruction, a power that can make everything into nothingness. " Sirzechs said to Yukina. Yukina couldn't react but felt shocked as the "fictional" character mentioned in the bible actually exist.

"Lucifer…. A devil king…." Yukina mumbled while looking at him.

In the Bible, the name Lucifer had been mentioned. In the fast, there were three factions fighting. Fallen Angel, Angel and Devils. They had conflicts and fight with each other. In the Great War, many Devils, Fallen Angels, and Angels were killed during the war. The reason that they stopped was because there were two dragons fighting, making the world in an unbalanced state. The world almost destroyed because of these two dragons, causing them to cooperate and defeat them. The dragons were the Two Heavenly Dragons – Ddraig and Albion. After they were killed, their souls were sealed inside Sacred Gear. Ddraig was sealed inside a mid-tier Longinus, Boosted Gear, and Albion was also sealed inside a mid-tier Longinus, Divine Dividing.

"I must let the Infinity Dragon Emperor cooperate with us. Unlike the past generation Maou, we hoped for peace more then anyone. From the last Great War, many factions were damaged. Our original Four Great Devil Kings was killed alongside many High-Class Devils. That's why I need to stop any war to let our kind extinct." Sirzechs said.

"But…" Sirzechs hesitated.

"But what?" Yukina asked feeling confused.

"I need to turn your brother into a devil to make him more powerful. As his current state, even with his Infinity Critical he couldn't survive damage from a Low-Class Devil. That's why by reincarnated him into a devil, he could train with us to become more powerful in the future. Wielding such type of Sacred Gear will make people come for your head, that's why you should be trained and protect yourself and the ones you love." Sirzechs explained the current situation Issei was in. As Issei indeed process a super powerful Longinus, and the Dragon Of Infinity was inside the Sacred Gear, there must be people who wanted to extract his Sacred Gear and kill him. Yukina looked at Issei's innocent face, patted his head, and asked

"Issei, do you want to become a devil instead of a human?" Yukina asked Issei.

"Um, it does sound fun! Onee-san, please make me a devil!" Issei said.

"Very well. Thank you Issei. I'll use Evil Pieces to reincarnate you into a devil. However, it is still not the time yet. I will call my sister who just became a high-class devil to turn you into a devil. My sister will be your master and you will be her servant. If you disobey her, you will become a stray devil. Do you understand?" Sirzechs said with a strict tone.

Yukina was angry about Sirzechs as she saw this was some kind of threat towards Issei. She ran to her side and hugged him tightly, making sure that he won't be attacked by someone else. However, she was also confused of what Sirzechs just said.

"um… what are Evil Pieces?" Yukina stopped her anger and asked Sirzechs.

After Sirzechs telling her about Evil Pieces, she found it interesting. She invited Sirzechs to sit on the sofa and asked him more about the Devil society and the Great War. As Sirzechs finished explaining, he stood up and looked at Yukina.

"Then I will be coming back for a few days. Good luck Yukina and the Infinity Dragon Emperor." Sirzechs said making a magic circle to teleport himself back to the underworld.

(A week later, Hyoudou Residence)

Issei was sitting on the sofa watching TV while Yukina was wearing an apron doing household chores.

[Now, after you become a devil, you will need to train yourself with Sirzechs' little sister. Although his sister is no way as strong as he is, you cannot look down on her. After all, she is a noble high-class devil. Make sure to treat her well.] Ophis warned Issei.

"Okay~" Issei said.

A magic circle appeared near the sofa making Issei look in curiosity. Yukina stopped working on her household chores, and ran towards Issei's side to wait for Sirzechs' arrival.

Sirzechs appeared, next to him was a beautiful girl with crimson hair. She was wearing a tidy, red dress with a gold bracelet on her hands.

"Hello Yukina, Hello Issei." Sirzechs waved his hands towards Yukina and Issei.

""Hello Sirzechs-sama!"" Yukina and Issei said together.

"This is my little sister that I was talking about. She will first live with you guys for a while before turning Issei to a devil. As she loved about Japan, this is also a great opportunity for her to observe the human world. Ria-tan, introduce yourself." Sirzechs said looking at Rias.

Rias looked at Yukina and bowed.

"Onee-sama! Please don't call me that name! *cough* My name is Rias Gremory, the heir of the House of Gremory. I will be living here for a short while, so please take care of me!" Rias raised her hands expecting for a handshake.

"I'm Hyoudou Yukina, you can just call me Yukina. Welcome!" Yukina said shaking Rias' hands.

"Um…. I'm Hyoudou Issei. Please call me Issei!" Issei said with a shy tone.

He couldn't help but find Rias cute. She never thought there was a girl that could compete or even surpass his sister's beauty. He stared at Rias quite a while, making Rias blushed.

"Well, since I'm a Maou, I have some duties to do. I will be leaving now. Please take care of my little sister, despite she was selfish and sometimes quite hard to deal with." Sirzechs said while teleport himself to the underworld. At the same time, Rias' cheek was as red as her crimson hair. She was embarrassed of what her brother said.

"So Rias-chan, since Issei was bored, can you play with him while I prepare dinner?" Yukina asked making Issei blushed as he can hang out with the beautiful girl standing beside him.

Rias and Issei walked to the garden and played for a while. They got to know each other and went back to the residence. Ever since, they started to get really good friends and even developed feelings towards each other.

(2 weeks after)

Rias and Issei was playing on the garden again. They were having a great time until Yukina came out and told them to come back.

After they came back while holding hands, they saw Sirzechs was sitting on the sofa in the living room. Rias immediately blushed as she never thought her brother came to the house without her knowing, most of all, she was holding Issei's hands.

"Rias, it seems like you are having a good time in the human world." Sirzechs laughed as Rias' cheek continued to become redder.

"Sirzechs-sama, they were playing all the time. I can hear a lots of laugh from Issei, making me feel happy as Rias was making him enjoy his life." Yukina said making Issei blush as well.

"That was all thanks to Rias. She helped me train everyday. I was able to understand more about my Sacred Gear's power as she guided me. After training, she will always play with me which made me feel happier all the time." Issei said while blushing.

"Issei, I need to thank you too. You made me feel happy ever since the day I meet you. I was always sad because my position as the heir of Gremory, many people gave me high expectations which made me feel frustrated all the time. But after meeting you, those pressures were gone as I was spending with you. I felt happiness and love when I'm be with you… Thank you Issei." Rias said as she hugged Issei tightly making Sirzechs shocked.

"Issei, do you love Rias?" Sirzechs asked Issei.

Rias was shocked and cover her face with her hands due to embarrassment. She loved Issei but she didn't know if Issei loved her as well. She couldn't get the courage to tell Issei her feeling, so the sudden question made her feel scared as she afraid that Issei will reject her.

"Sirzechs-sama, yes. I love Rias with all my heart." Issei said with a shy tone. Although he was embarrassed, he couldn't hide his feelings towards Rias anymore. He loved Rias no matter who she was, as she was the one who gave him a lot of happiness.

After Rias heard it, tears of joy starting to stream from her eyes. She kissed Issei on his lips and hugged him tight.

"Issei! I love you too!" Rias said making Issei shocked by her actions. However, he hugged her back and kissed on her cheeks.

'I never saw Ria-tan this happy before….. Wait this is not why I'm here today!' Sirzechs thought to himself.

"Ria-tan, it is time for you to make Issei your servant. Take out your evil piece and check how much piece Issei worth." Sirzechs said as Rias nodded and took out her Evil Pieces.

The only that she used was a queen piece. As Issei had a powerful Sacred Gear, she needed 8 Pawn Pieces to reincarnate him to a devil. She then took out 8 Pawn Pieces and place it on Issei's heart. The Pawn Pieces began to glow and Rias asked Issei.

"Are you ready Issei?"

"Yes indeed I am. Ophis, you?"

[Of course I'm ready. Let's go.]

"In the name of Rias Gremory, I call you, Hyoudou Issei, surrender your sole and become my trusted pawn."

8 pieces turned to a crimson colour immediately after the ritual. They were mutated as the powerful Sacred Gear Issei process. The pieces got into his body one by one. But on the last one, the Evil Piece started to turn into a jet-black colour making Sirzechs and Rias shock. The Jet-Black Pawn Piece flowed into Issei's body as well.

"Wow Issei… You became a devil" Yukina said with a surprised look.

Four wings appeared behind Issei's back, making Sirzechs and Rias confused even more.

"Wait.. I thought only the original Devil King or the descendent of the original Devil King had four devil wings… Why?" Rias asked in confusion.

[Since Issei process my power, it is normal for him to have four wings and the evil piece to be mutated. However, one of the mutated piece turned into the jet-black color. In this case, it turned into a super-mutation piece as eight normal mutated piece cannot accept the power of infinity. A pawn piece needed to be turned to be able to accept Issei's great power.] Ophis said making Sirzechs and Rias shocked.

"Alright. Issei you had finally reincarnated into a devil. Ria-tan, let us go back to the underworld to continue your training." Sirzechs said walking to Rias' side, but Rias ran to Issei's side and hugged him.

"No Onee-sama! I don't want to leave Issei!" Rias shouted hugging Issei tighter and tighter as she didn't want to leave Issei.

"Hmm…. Seems like you want to hang out with your new boyfriend. Very well. You couple over there come with me to the underworld and train." Sirzechs then made a magic circle telling Issei and Rias to follow him.

"Issei! Be safe alright? Come back as quickly as possible!" Yukina ran into Issei's side and gave him a hug.

"Yes Onee-san, I will come back once I finished the training." Issei hugged Yukina back.

Issei walked into the magic circle and Sirzechs began to telport him to the underworld. He trained and played with Rias for 10 years, not with the relationship of master and servant, but as a lovely couple.

(9 Years After)

(Underworld)

Rias grew to be a beautiful and 1.7m tall with a voluptuous body. Her crimson hair perfectly matched her beauty, as a result she was considered everyone's ideal girlfriend. Issei became a handsome and 1.76m tall man. Her handsome appearance attracts many girls while boys hated him for his attractiveness.

Rias and Issei was sitting on the living room in the Gremory mansion, and Rias decided to tell Issei some big news.

"Issei, I will be going to the human world and study as a first-grader in high school." Rias told Issei making him feel surprised.

"Hm… then I guess good luck then." Issei said with no reaction. Rias was kinda angry because Issei didn't react to her sudden leave. She expect Issei to be missing him and much more but he just simply said like he didn't care.

"What do you mean by good luck?" Rias said with an annoyed tone.

"Well, I was going to tell you that I will be training with Tannin, the former Dragon King. I will be training over a year and I will be joining the same school as yours Rias." Issei said patting Rias head to make her calm down.

Rias kissed Issei on his lips and began to talk about something else.

(1 Year After)

(Hyoudou Residence)

"Issei! Remember to bring your school bag! Don't be late on the first day of your school!"

"Ok Onee-san, I'll double check my things now."

Issei went back to his sister's home after the training. He had trained his body and developed a muscular body. He has great physical and good stamina thanks to Tannin's training. As a result, his fighting abilities were also improved.

"I'm heading!"

Issei opened the door and started to walk to his new school – Kuoh Academy. It was a girls-only school until two years ago as it changed to a co-ed school. When he was walking towards the school gate, people around started to whisper.

"Oh my god! He is so handsome!"

"A new student! He is as handsome as Prince Kiba!"

"I think he is more handsome, should he be the second Prince of Kuoh?"

"Not a prince but a King!"

Girls seemed to be excited about Issei's arrival.

"Damn it! Another bishounen!"

"With his existence we will never going to get a girlfriend!"

"Yuck! Go die you handsome boy!"

Boys apparently thought differently.

Issei went to the General Office and finish his registration procedure as a transfer student. After the bell rang, a teacher came to greet Issei.

"Hello Hyoudou Issei-kun, I'm your homeroom teacher, Asuka-sensei. Please follow me so I can lead you to your classroom."

Issei then followed her to the classroom. When he passed by classrooms, many students look at the window to see Issei's handsome appearance. However, Issei didn't care for a bit as he only wanted to meet one person – his love Rias Gremory.

He was informed beforehand that Rias was studying in this school. Sirzechs secretly put him in the same class as Rias without her even knowing.

As Asuka-sensei and Issei walked into their classroom, people started to whisper again.

['This is definitely weird.'] Ophis said in Issei's mind.

'I know right…. So annoying.' Issei said in his mind.

['Is that Rias Gremory?'] Ophis said making Issei to look at his new classmates.

Issei found a crimson-haired girl chatting with her classmates. He couldn't help but grinned as he finally found the one he loved.

"Everyone, welcome to Class 2-B. I'm Asuka, your homeroom teacher. Now, next to me is a new transfer student who just went to school for the first time. Mr Hyoudou, can you introduce yourself?" Asuka-sensei looked at Issei to introduce himself, he nodded and began to speak up.

"Hello everyone. My name is Hyoudou Issei. A new student in here. Since it is the first time I have ever attended to a school, I will definitely need support to adapt my school life. I hope that we can get along in this year. Please take care of me!" Issei said bowing to his classmates.

"Now, do any of you have any questions for Issei-kun?" Asaka-sensei asked.

A girl with glasses raised her hands. After she stood up, Issei noticed that she was wearing a pair of glasses, with brown eyes and brown hair. He didn't know why, but he felt that she was probably a pervert.

"Hyoudou-kun, do you have a girlfriend?" The girl asked making everyone waiting for his answer.

Suddenly, another girl stood up.

"Issei… is that you?"

Rias POV

I was chatting with my classmates because this year will be another year of my human world school life. I am so happy but also feel sad as I can't see Issei anywhere. He said that he will be here after his training, but apparently he is not here. Maybe he will be coming in a few days?

While I was thinking about it, my homeroom teacher came in and began to introduce herself. I don't care about the introduction so I continued to chat with my classmates. Until I heard this :

"Mr Hyoudou, can you introduce yourself please?" Asuka-sensei said it making me think about who is Mr Hyoudou.

Issei's surname is Hyoudou! So does that mean….

"Hello everyone. My name is Hyoudou Issei. A new student in here. Since it is the first time I have ever attended to a school, I will definitely need support to adapt my school life. I hope that we can get along in this year. Please take care of me!"

That was Issei! My lovely Issei! He was finally here! I couldn't react as I was totally shocked. I was stared at him as long as I can. I really missed him! When I heard that the female pervert Kiryuu Aika asked him if he had a girlfriend or not, I jumped out of my shock and stood up.

"Issei… is that you?" I asked hoping him to be the Issei I know.

Third person POV

"Oh Hi Rias! That's me. I missed you so much." Issei said making Rias blush.

Rias ran to Issei and hugged him tightly. Everyone was shocked to see this scene. The most beautiful girl in the school just hugged the new transfer student!

"What…. What is your relationship with Rias-san!" the female pervert asked Issei in disbelief.

"Yes! Who are you! Why you are hugging Rias!"

"No… I can't make Rias my girlfriend anymore!"

"She is stolen!"

"He is stolen!"

The boys and girls started to feel sad about the situation. Issei cleared his throat purposely to make everyone silent. Rias ignored other people's comment and still hugged Issei tightly.

"My girlfriend is the beautiful lady here, Rias Gremory." Issei said kissing Rias on her forehead.

"I love you Issei! I missed you so much" Rias said kissing him back.

After a moment of silence….

"WHATTTTTTTTTTTTT?"

A/N Alright i think Ophis should be sealed inside a Sacred Gear while Issei was the wielder of it. Abilities such as Balance Breaker, Juggernaut Drive will still be present. Please write reviews to let me know what do you guys about the story and more. Thanks
