I do not own KHR!

The next day, Tsuna was sitting around, resting after his once again Spartan training when suddenly the automatic door slid open. Tsunayoshi looked up and widened his eyes as familiar dark eyes greeted him.

"Good afternoon, Tsunayoshi ji-san." Kazuya greeted.

"Good afternoon, ojii-chan." Rei said, peeking from Kazuya's back.

"K-Kazuya-kun! Rei-chan! Why are you here?" Tsuna said.

"I was told to come here by father, Tsunayoshi ji-san." Kazuya said, smiling casually at him.

'At least he's not as stiff as Hibari-san, I guess he got Sora-chan's smile then…' Tsuna thought.

"Onii-chan is gonna test oji-chan!" Rei said as she walked towards Fuuta.

"So Hibari planned all of this by himself?" Reborn said as Fuuta carried Rei in his arms.

"Yep, Papa just love testing people. Onii-chan loves them too!"

"W-What?" Tsuna said as he watched as Kazuya smirked and took out a box.

"Y-You have a vongola box?"

"This was given ever since the box was found, Gianinni-san made me my own box, as well as Rei's." Tsuna's eyes widened even more when Rei waved her own box at him while smiling.

"Let's get started, shall we, Tsunayoshi ji-san?" Kazuya said coldly as cloud flame lidded tonfas appeared out from the box.

"You have the cloud flame as well?"

"Family ties are the strongest, Tsuna. And he is not to be underestimated, being the son of the Cloud Guardian." Reborn said as Kazuya disappeared from Tsuna's sight.

"E-Eh?"

"Please concentrate, Tsunayoshi ji-san, or I'll bite you to death." Kazuya said, hitting Tsuna's side.

"H-He even got Hibari-san's personality!"

"Why thank you, it's an honour if you think I'm similar to father." Kazuya said, smiling.

'… I take my words back! Facing Hibari-san is a much better choice than facing his smiling son but also powerful and scary son!' Tsuna cried in his mind.

"Don't get distracted Tsunayoshi ji-san, or you will have your flame wiped out." Kazuya said, charging once more towards Tsunayoshi.

"H-Hiii!"

Few moments later, Tsuna lay all beaten up on the floor. Kazuya didn't give him a single moment to swallow his pills. Kazuya sighed and let the cloud flame died down and his tonfas disappeared back into the box.

"Tsunayoshi ji-san… as father said, I am disappointed, it seemed that you cannot even lay a single hit on me…" Kazuya said with his eyes cold staring to the shivering Tsuna.

"But I didn't even manage to eat the pills!" Tsuna yelled as Kazuya shook his head.

"Tsunayoshi ji-san… you cannot always rely on the pills, you have to think clearly first. You have to manage to slip the pills while you are trying to dodge everything that came to your way." Kazuya said.

'I can't believe I'm being lectured by someone younger than me… especially Hibari-san's son…' Tsuna thought.

"Onii-chan… are you done yet…?" Rei said sleepily from Fuuta's arms as Fuuta placed her down on the floor.

"Did I take too long, Rei?" Kazuya said, taking Rei's hand.

"Tsu oji-chan hasn't become stronger yet… it's not fun…" Rei pouted.

"A-Ah…"

"But Tsu ji-chan always got something, Mama said so! Tsu ji-chan is a man full of surprises!"

"You always believe what Mama said, don't you Rei?"

"Of course! Mama never lies to me… only that one time…" Rei said sadly as Kazuya kissed her forehead.

"Come on, let's go. We should go back home." Kazuya said as Rei nodded. Tsuna watch as Rei started to close her eyes before it snapped back open.

"Onii-chan! hurry hurry! It's time!" Rei said, smiling very widely Tsuna thought her little face would break because of it.

"Is it already? Come on, we better leave. Excuse us, Tsunayoshi ji-san." Kazuya said as he bowed and ran towards the elevator.

"See you later, Tsu ji-chan!" Rei waved as Tsuna waved back before the door closes on them.

Rei and Kazuya had stepped into a room. The room was filled with flowers, it was a special room, detached from the Vongola base. In the middle of the room, a coffin was placed; a white and beautifully decorated coffin with flowers decorated the inside. A woman with long brown hair was lying inside, her eyes were closed and her hands were placed together as if she was in a prayer.

"Mama, how are you today? Tsu ji-chan came; he looked funny. But he seemed really nice, like how you used to describe him when he was younger." Rei said, tip-toeing so she could peek inside the coffin. When Rei saw her mother's face, her eyes quickly moistened as droplets of tears fell into the coffin.

"Mother, Rei and I have been fine, we miss you so much. But father seemed to be in rage… when he saw the past Tsunayoshi ji-chan, he couldn't help but fell angry… please watch over us, mother. And please help father." Kazuya said, looking towards his mother's serene smile.

"Mama, will you come here too? I really want to see you… I miss you Mama, I want you to play with me again…" Rei sobbed as Kazuya placed his hand on Rei's shoulder.

"We all missed you mother. Father said that they are on the move, so he wants us to stay safe… please watch over him too, so he wouldn't get himself hurt. Father has been very lonely since you left, even if Rei and I stayed by his side, it's nothing like when you were alive… Father was much more lively back then, father has been putting distance between us, so I hope he wouldn't do anything that would put himself in danger…"

"I love you Mama…"

"I love you, mother."

"M-Mother?" Rei and Kazuya turned around and saw Tsuna standing with all of his guardians, even Chrome.

"T-Tsunayoshi ji-san! How did you get in here?" Kazuya said in shock.

"C-Chrome saw you coming here… I was curious when Rei-chan said 'it's time' so… I…" Kazuya looked towards the coffin and Rei then spread his arms.

"Please don't come over here!" Tsuna's heart was beating frantically when he saw Rei's red eyes as well as Kazuya's worried expression.

"W-Who's inside that coffin…?"

"Please! Tsunayoshi ji-san! Don't make me hurt you! Please don't come over!" Kazuya said as Rei pulled his arms.

"Onii-chan… mama might want to see him too… Tsu ji-chan has arrived here… we can't just put him away… Tsu ji-chan might get curious even more…" Kazuya then lowered his arms.

"… you're right, Rei… but Tsunayoshi oji-san… I wouldn't recommend you to come here…" Kazuya said as Tsuna took a step forward. When Tsuna had stood right in front of Kazuya, his eyes held determination Kazuya couldn't help but look away towards Rei.

"Rei…"

"Will Papa be mad…?"

"I'll help responsibility for this… don't worry." Kazuya then stepped aside from Tsuna's path. Tsuna then walked closer towards the coffin and gasped in shock.

"H-How could this be…? T-This is…" Tsuna couldn't finish his sentence as he watched the body inside the coffin.

A body lying on top of a coffin surrounded by flowers, a very familiar face greeted him and it hurts. It was his own cousin, his dearest cousin. A smile graced her face, the smile she used to give him when he was in a panic. Tsuna heard his guardians breath hitched as a sob escaped his Mist Guardian. Tsuna lowered his head and watched as a young girl and a boy stood looking at him with the girl still crying since he had entered the seemingly holy place. The boy was carrying the girl in his arms now; his eyes are also moistening.

"This is our mother, Hibari Soraoi." The boy said as Tsuna's heart skipped a beat. How could this be…?

"How could this happen…? Sora-chan…?" Tsuna said as his eyes were filled with tears.

"Mother was killed… she was ambushed, by Millefore."

"Millefore?" Gokudera yelled in anger.

"Goku ji-chan, please don't yell… Mama doesn't like people yelling in anger…" Rei said as Gokudera quickly composed himself. Rei then jumped down from Kazuya's arms and walked towards Chrome.

"Chrome oba-chan… don't cry…" Chrome saw Rei looking at her with red eyes and quickly enveloped her in a hug.

"Rei-chan…"

"Please don't cry… Mama doesn't like seeing people crying for her." Chrome nodded and patted her head.

"Mama was gathering information on Millefore alone… she was suddenly ambushed… she was discovered, Tsu oji-chan and the others went over to find her and Chrome ba-chan was the first to find her and father then brought her back here…"

"Her body is…"

"Bianchi ba-chan tried her best to fix Mama, but Bianchi ba-chan couldn't do anything… mama was told to have died before Papa and the others find her…" Rei said, sobbing in Chrome's arms.

"Then Hibari-san…"

"Father was very heart broken… Tsunayoshi ji-san must have known how much father loves mother… father changed greatly ever since." Tsuna remembered how serene and happy Hibari's eyes are when he was with her cousin in his time. Now he is in the future and they had gotten married, he could never understand the depth of their care towards each other since then so he couldn't have understand it now, but he knew Hibari must be the one who suffers the most.

"Father was angry with you since you let her go so easily, Tsunayoshi ji-san… and he is also angry towards himself because he wasn't able to prevent her from leaving…" Kazuya said. Tsuna looked towards Soraoi's smile and he tightened his fists.

"Sora-chan… why are you smiling…?"

"Mama was smiling ever since she was found, Bianchi ba-chan said… Fuuta nii-chan couldn't understand as well…" Rei said. Suddenly Kazuya and Rei's head looked towards the door and Tsuna knew he shouldn't turn around.

"Why are all of you crowding here?" Hibari said murderously.

"Father! Let me explain…!" Kazuya said before Hibari lifted his hand.

"Get out. Now." Hibari said, eyes blazing with rage and anger. Tsuna then quickly ushered his guardians out.

"Sawada Tsunayoshi, you disappointed me before, if you dare step into this room once more. I will not hesitate to bite you to death. Kazuya, you let your guard down." Kazuya looked down on the floor as Rei stood in front of him.

"Papa! Don't be angry to onii-chan! He didn't do anything wrong! We didn't notice that anyone saw us coming here! Mama was getting lonely! I'm sure she'd be happy is someone visited her…" Rei said as Hibari lowered his hand.

"Rei."

"No! Mama is sad because Papa is different! Mama is sad because Papa has been getting angrier and angrier!" Tsuna's eyes softened at Rei whose eyes bear flames like Soraoi's.

"Rei…" Kazuya said, trying to hold Rei back.

"If Papa keeps getting angry! Papa will only make Mama sad! Mama would never want Papa to be like this!" Hibari sighed. Tsuna took this chance to give the family some time alone as he pushed everyone out from the room.

"S-Sora-san is…" Gokudera said, fist trembling.

"Sora…"

"Soraoi-chan…" Chrome said, tears dropping onto the metal floor as Bianchi and Fuuta tried to cheer them up.

"There is no use crying over her, Tsuna. Imagine what she would say to you if she is alive right now." Reborn said as Tsuna let a tear dropped onto the floor.

"Soraoi nee died with a smile, whatever the reason, I am sure she's happy right now." Fuuta said.

"Last time we saw her, was when she debated with the future you when she wanted to leave to gather information on Millefore."

"So… her last memories of me were a bad one?"

"No, I think her last memories of you were of you worried for her safety. But I'm sure she is watching over us now, hoping for us to stop grieving for her and focus on what is happening now." Bianchi said.

"Aneki is right, if Sora-san is alive, she might get angry at us for doing unnecessary things." Gokudera said.

"Even if she died now, you can prevent the same thing from happening by defeating Millefore, right? If Millefore is defeated, Byakuran wouldn't target Soraoi-chan." Bianchi said.

"According to my information, Byakuran had seen Soraoi nee somewhere before in this time and was attracted to her. When Byakuran knew Soraoi nee is married to Hibari-san, he quickly sent soldiers to ambush her. Soraoi nee is a person who would know if she was being tailed, but I guess she didn't see this one…" Fuuta said.

"That's it! We should defeat Byakuran! I couldn't let anyone suffer anymore! Rei-chan and Kazuya-kun lost their mother! And Hibari-san is also suffering because of it! Byakuran should be defeated!"

"You're right, Tsuna. We couldn't let the same thing happen to Sora." Yamamoto said.

"I agree tenth! If we defeat Byakuran, we can make sure no one else suffers!" Gokudera said, eyes blazing.

"For Sora-chan." Chrome said.

"That's the spirit, Sawada-san." Tsuna then saw Kusakabe at the door and quickly walked over to him.

"How is Rei-chan and Kazuya-kun? Hibari-san didn't do anything to them, right?" Kusakabe laughed and patted Tsuna's shoulder.

"Kyo-san would never do such a thing to them. He might be angry yes, but he would never hurt them, ever. Rei and Kazuya are currently back in their room, being punished to sit the whole night away."

"T-That's… perfectly normal…"

"Kyo-san would dare to hurt his children. He never could. He's very admirable." Kuasakabe said as Tsuna sweat-dropped.

"Hibari-san… is a decent father after all…?"

"A very responsible one as well. He has soft spots for both Rei and Kazuya."

"I see…"

"Rather than standing here doing nothing, how about all of you train to prevent this from happening?" Reborn said.

"Yeah!"
