The rest of the Summary:

This fanfiction takes place in an Aleternate Universe, where Ghenna and Assiah sit right next to each other; as if they were two cities standing next to each other. Rin is one of the Prince's of Ghenna, having been stolen from Assiah shortly after he was born, and is the next successor of Satan.

After his six year punishement is lifted, Rin ends up finding himself drunk to no extent and in bed with an Exorcist named Bon (yes this is another BonXRin fanfiction!). The Prince soon finding out he has mated with the exorcist and his brothers are after his title, making the young Prince the target of every demon in Ghenna. When Rin is injured and taken in by Bon, will his feelings for the teen grow; or will they be torn apart by Amaimon, who is after the young Prince? And what will happen with his Father's retirement nearing it's close? Will he survive to be King, or will he be killed by his people?

Chapter 1-

"Prince, move!" yelled the half-demon bodyguard as gunshots went off.

"Treavor, give me a lift!" the other half-demon bodyguard shouted, running toward his twin.

The next moment, Treavor boosted his twin brother the air, and suddenly the bodyguard was in front of the smaller demon, just in time to deflect the bullets that had been heading right for the Prince, the dangerous capsules ricocheting off an invisible shield and falling to the ground. Rin looked up at the older male in complete shock and fear. His bodyguard, Trey, grabbed his hand and shoved him into his twin's arms, ordering Treavor to take the demon to safety before the exorcists could kill him. Treavor quickly obeyed, picking up the young demon and running for it, leaving his twin behind.

One of Rin's father's black SUVs screeched to a halt as the two of them made it around the corner. The door opened seconds later, and Treavor quickly got the two of them inside, setting Rin in the only empty seat available—the back—and sliding into the passenger seat himself. The car took off at an alarming rate, and the demon girl in the driver's seat made a sharp turn, passing the huge fight they had been in only a few seconds ago, driving right past Trey.

"Lina, we have to go back!" Rin yelled desperately as he watched his bodyguard leave his sight.

"We can't do that, Rin," Lina said sweetly before making a sharp turn in the middle of traffic and cutting off a lime green bug convertible. "Our job is to protect you, not Trey; even he knows that, Rin."

"Bu—"

"Don't argue, Rin," Treavor cut in, looking back at him. "Your father assigned us to protect you, and that's what we're going to do, so no more arguing. Trey knows what he's doing."

"Fine!" Rin pouted, bringing his little knees to his chest and looking out the window.

The scenery outside was blurred thanks to Lina's expert driving; his older sister was known for it. The both of them were children of Satan, and the most feared beings in Ghenna's Territory. Lina was the best shot with a bow and arrow, and a deadly driver, her body itself a deadly weapon. Her skin was poisonous to the touch—if she chose it to be. She had control over her inner venom and lavender flames at their peak, making her an expert assassin at her young age of twelve.

Rin was a pathetic age of nine, and the easily distinguished successor of his father. The small child was the carrier of the cursed blue flames, and his control over them was as bad as his temper, making him a ticking time bomb waiting to go off. He was the youngest child of Satan in Ghenna's territory, and the most feared, which is why the young boy had been given bodyguards, both of whom were half-demons with the best senses in all of Ghenna.

The twin half-demons, Treavor and Trey, were both at the age of fourteen and in no way alike when it came to their personalities, Treavor being the calm and relaxed twin, while Trey was the active and annoying type. The two of them looked exactly alike, but were completely different on the inside. The same went for their abilities, Trey having the ability to control the matter around him, create invisible shields in thin air, and turn invisible at will, while Treavor was born with the ability to see ahead in time—though not when he wanted to—and the ability to control water with a simple flip of the wrist, making it almost impossible to injure or capture the young demon under any circumstances.

"Rin, hide your tail. We don't want father knowing you got caught using your flames, again," Lina ordered as she drove into Ghenna territory. "You'll get grounded again."

"Then let him ground me!" Rin yelled, turning to glare at the back of his sister's head. "The humans don't like me, anyway! I don't see a point in being able to leave Ghenna, anymore! Humans are mean!"

Lina let out an irritated growl and turned into the driveway to their father's mansion, their older brother Mephisto waiting at the top of the stairs. The three of them were silent as Lina parked the car, and Treavor opened the door for the little demon to jump out, stepping over all the junk in the back of the car.

"Well, it looks like someone disobeyed, again, now doesn't it?" Mephisto teased, messing up the little demon's hair.

"Go to hell!" Rin growled, flipping his older brother off before storming inside.

Six Years Later

"Oh, Princey! Wake up and get your lazy ass out of bed!" an all too familiar voice rang in his ears. "We've got loads of things tah do today!"

"No we don't, Trey. Get the fuck out of my room," Rin growled as he rolled over in bed and pulled a pillow over his head. "It's still two in the morning."

"And that's exactly why I'm wakin' ya up!" The half-demon cried out, pulling the pillow from the Prince's grip. "Today's tah day your punishment gets lifted!"

"What punishment?" The demon growled, as he sat up and rubbed his eyes, taking the pillow back. "I don't remember getting a fucking punishment."

"Ya did, Rin, remember? It was six years ago, when I got my last taste of combat! Ya were nine!" The demon's bodyguard got a "do I look like I care" look from his charge, making him sigh. "Ya used your flames by accident and we got attacked by a bunch of exorcists."

"Oh, that," Rin growled, feeling a wave of displeasure wash over him. "Don't remind me."

"Come on, Princey! Your punishment is lifted in five minutes!"

"Trey, go back to bed!" Rin growled, laying back onto his bed and pulling the pillow over his head again. "I don't give a fuck if I'm unpunished or not. I'd rather rot in this hellhole, than be in the presence of humans!"

"Fine, Princey. Looks like it's Plan B, then!" The half-demon took the Kurikara off his desk cheerfully and ran away with it in his grasp.

Rin automatically noticed its presence disappear from the room as the bodyguard ran down the hall, pissing off the Prince even more than the half-demon would ever know. Rin angrily got out of his bed and dressed himself, storming out of the room in search for his bodyguard. The Prince was wearing nothing more than a pair of black skinny jeans and a grey t-shirt with a skull design on the front, the demon not having bothered to even cover his feet. As Rin angrily walked down the hall and passed all of his brother's room—probably waking them up due to the anger welled up inside him—his blue flames begged to be released. He walked down the stairs and saw his Royal Guard waiting for him, Trey holding his sword.

"And Princey makes it in record time!" Trey announced, his voice echoing in the open room.

"Trey, you of all people should know not to fuck with me in the morning," the demon growled, walking over to his bodyguard and snatching his sword away from the annoying idiot, "let alone this early!"

"Get it over it, Grumpy!" Lina snapped, smacking him in the back of the head. "All of us got up so we could celebrate your punishment lifting. And quit swearing, you have two eight years olds and a nine year old in your Royal Guard! Try and be a role model for once!"

"Go find someone who cares!" Rin shouted as he headed for the stairs. "I wanna sleep in!"

"You've been sleeping in for the past two thousand one hundred and ninety-six days, Prince," his twelve-year-old half-demon doctor pointed out, "if you count the two leap years."

"I still don't give a fuck, Drew!" Rin yelled. He felt a tug on his jeans. "What?"

The Prince looked down to see the two eight-year-old demon girls, Kimi and Kati, looking up at him, their gold eyes pleading for him to go with them. The two of them were practically identical, both with the same skin tone and strawberry pink hair. The one the left, Kimi, was wearing black tank top under armor, a red t-shirt with the shoulders cut off, dark denim jeans and black tennis shoes. Her hair was cut extremely short, and a big black and blue "R" was tattooed onto her right cheek, an identical one on her sister's right shoulder. The tattoo symbolized their loyalty to Rin as his protectors. Even though he had told them not to tattoo his fucking name on themselves, the two of them had bent the rules and got the first letter of his name tattooed instead.

The girl on the right, Kati, was wearing a bubble gum pink shirt and chocolate brown boots, the cuffs made of a softer material, her strawberry pink hair past her waist and in pigtails. She wore a red tank top, with the right shoulder cut off and replaced with a t-shirt sleeve, black under armor, the right sleeve also missing, making the two of them adorably cute in anyone else's eyes, but deadly in Rin's. The two of them could kick his ass if he pissed them off, which he wasn't planning on doing today.

Rin looked over the rest of his Royal Guard.

His twelve-year-old half-demon doctor, Drew, gave him a disappointed look. His Caribbean blue eyes glowed bright in comparison to his short brown hair and slightly tanned skin. The guy was wearing a traditional lab coat, grey V-neck, and light washed skinny jeans; he wore a pair of traditional dress shoes on his feet.

Rin's older sister, Lina, was standing next to him, her pink hair cut short and her blue eyes waiting for him to make a decision. A pair of baggy jeans and a cream hoodie hung loose on her figure, a pale pink tank top under the hoodie, black shoes, and a nine year old guy in front of her.

That same nine-year-old, Kira, had his left eye covered in bandages, leaving his one brown eye visible, and had his black hair pulled back in a ponytail. The boy was wearing a brown long sleeve shirt with the shoulders cut off, and a black tank top over top of it; on his lower half were a pair of Capri's and black tennis shoes.

Then there were the dreaded twins, Treavor and Trey, right up front. The both of them were wearing identical clothes, but the sizes were way off. Treavor wore a grey sweater that would've fit Trey, an oversized pale purple shirt, and black jeans. Trey was obviously wearing Treavor's oversized grey sweater, his own pale purple t-shirt, and black skinny jeans; the both of them dressed in dark purple tennis shoes. Their dark purple hair was cut short and spiked, their grey eyes watching him.

Finally, Rin gave in, sighing.

"Fine, but only this once," Rin muttered, before adding, "and if one human bothers the hell out of me we're coming right back!"

Trey, being the idiot he is, let out a cheer and picked up the Prince, carrying him out of the house and to Lina's old SUV, before opening the door and setting him in the middle of the back seat, the rest of his Royal Guard scrambling after him. Kimi and Kati sat on either side of him, Trey in the passenger's seat, Lina in the driver's, Drew sitting on the floor, and Kira and Treavor in the seats in front of him, as the demon let out an irritated huff and leaned back in the seat. Lina started the car and headed for the border of Ghenna's territory.

"Humor me, and remind me why I have all of you to protect me," Rin asked with a frown, "and where the whole Royal Guard thing came from."

"The Royal Guard concept was created by your father when your first brother was attacked and almost killed by an exorcist," Drew explained, turning to look at him. "He gave him an assorted group of demons to protect them and named the group the Royal Guard since your brothers are practically royalty here. Every Prince has had a Royal Guard, but a few choose not use them."

"So why do I need you guys?" Rin asked, frowning.

"Because your temper outweighs your ability to control your flames, you need protection, and you are the youngest Prince, and successor of your father," Drew said, giving the Prince a frown in return. "You're Ghenna's most prized possession."

"Then why am I leaving to walk around Assiah's territory with a bunch of humans?" Rin pressed.

"Because you haven't left that damn house in six years, Rin," Lina said as she turned a corner. "You need some fresh air and a nice atmosphere to walk around in."

"Just open a window, I'll get plenty of air."

"You need more air than that, Prince Rin." Kimi spoke sweetly, smiling at him.

"And some sun, Prince Rin," Kati added.

"What did I tell you people about calling me Prince?" Rin growled. "I can understand Trey trying to piss me off with it, but I hate being called a Prince."

"It's customs, Rin," Treavor said, looking back at him, "but don't worry, we won't call you 'Prince' in Assiah's territory. It's too risky and dangerous."

"Whatever," Rin muttered.

"We're nearing the territory line!" Lina announced.

"Princey's got forty seconds!" Trey said, looking at his watch. "Slow it down a bit, Lina!"

"I'm going twenty! If you don't like it, shoot me!"

"We'll smash the car, thanks to the barrier, if you don't slow it down to at least fifteen, Lina." Treavor warned.

"Fine!" Lina growled, easing off the gas. "I hate driving slow."

"We can drive at forty on the way home if it'll make ya happy," Trey sated her, grinning back at everyone. "Give tah kiddies a taste of your expert driving."

"Deal!" Line gave Trey a high-five and grinned.

"Five seconds!" Trey called out, a huge grin on his face. "Four, three, two, one!"

Rin does not belong to me. These characters belong to Kazue Kato.

The Royal Guard Chracters belong to me. Ask if you want to use them and do not steal.

Vocabulary I Made up and Use:

Royal Guard: A group of assorted demons that are given to a Prince to protect him from potental enemies. Not every Pirnce uses their Royal Guard.
