Their adventure has ended. The Arcobalenos have been freed, Vongola no longer had the shadow of Daemon looming over their shoulders, and they were all happy. It was peaceful.

The guardians, Reborn, and maybe some others are now seeking the truth of what happened to the brunette in the last 2 years. But will they be prepared to discover the truth? What if Tsuna, himself, has forgotten what has occurred? Graduation also seems to have a special event coming up.

KHR and Assassination Classroom crossover Tsuna was an assassin. His intuition and shot were unrivaled. He knew many people in the Mafia including the infamous assassin Serpentine.

The two teens struggle to hide their identity as suspicion closes in on them. "What do you mean that I'm an assassin, Koro-sensei?" "That's quite a wild conjecture, Reborn."

Tsuna was abandoned by her guardians and Tutor for her sister. In despair and sadness she accepts a letter to Class E in Kunugigaoka High. Will she ever open up again or always stay closed from the world with her guard up. "Why am I so Important?" "Because...You're....the sky...my sky♡"

It was a peaceful day for Tsuna and the others; no dying will bullets, no bombs flying around, no clashing of swords. It was just a battle against a seemingly never ending numbers, Nezu's tauntings, and wait....why was there a yellow octopus in front again?

We've seen the classic "Class Trip to Italy" trope. However, what if instead of the 3rd years from Namimori going, it's the 3rd years from Kunugigaoka? Assassin and Mafia collide in the best, or worse, way.
