Cute Innocence [CROSSOVER]

What Sin?

Tsuna and Hinata's POV

This headache....... Is different. Different from the sickness. It's like when someone recovers from. Ⓐ Ⓜ Ⓝ Ⓔ Ⓢ Ⓘ Ⓐ . We fell unconscious on the floor with eyes open then everything went black.

The three groups of seven rings(Trinisette) showed up. Each one being destroyed by someone scary. His image is blurry. The world's balance is also destroyed. Everyone is seen committing deadly sins. No matter how hard I tried to remember his face, my head will hurt more.

Daydream ended

My eyes are wide open. I am still scared from that headache or sickness and then I suddenly remembered-

No one POV

"Where is Kuroko/Kuroko-kun?!"the two woke up from their subconsciousness. Their voice filled with fear. The crowd looked at the two feeling relieved. They helped the two to stand up. The two held their foreheads.

"Wh-Where is Kuroko?"Hinata still feeling his pain asked. Reborn and the guardians looked at each other and looked at the strange behavior of the two.

"Ku-Kuroko? He is not yet here"Chrome stated.

"Kufufufu~Now that you have said it, maybe he is suspicious"Mukuro thought.

"Search for that teal boy~"Byakuran ordered. Everyone looked at Byakuran.

"Tch why do we need to search for him?!"Gokudera tched and opposed.

"Ahahaha, maybe he is doing something important!"Yamamoto grinned and his face turned to frown.

"LET'S SEARCH FOR HIM TO THE EXTREME!"Ryohei shouted/suggested.

"Lambo-sama is too tired~"Lambo drifted to sleep.

"Hn"Hibari walked out. Who knows maybe he will search for Kuroko.

"Mukuro-sama?"Chrome turned her head to Mukuro. Mukuro just giggled and nodded in response.

"What the?"Tsuna thought as he stood up.

"The pain is gone!"Hinata stood up quickly and checked his body.

"Woah, woah woah~you can't go yet"Byakuran stared at the two who are feeling healthy right now.

"What matters right now is Kuroko is missing"Hinata sighed.

"My intuition is acting up"Tsuna said to others.

"Then we must find Kuroko at any cost before it's too late"Reborn demanded.

"My guardians will find him too~"Byakuran signaled his guardians. His guardians left the room already.

"Let the Hide and Seek begin!"Reborn clicked his finger and everyone hurriedly left the room to find Kuroko. Hinata stopped in front of Byakuran.

"You are almost like Oikawa! Too weird!"Hinata pointed at Byakuran and left the room. Byakuran giggled at the clueless Hinata.

"These two must be related to something special that my parallel cannot tell to me~"Byakuran frowned. He remembered what his parallel worlds gave clue to him:

"The true sin cannot be erased easily, it is held by grudge and betrayal. No matter how much you erase it, it is always by your side"it made Byakuran angry. He doesn't know if they are talking about him or what happened when Byakuran committed many sinful acts in the past when he was in Millefiore.

Who are they?

Why are they here?

Is there a reason?

Are they related to mafia?

But they are still in highschool?

What sin?
