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. Nagisa was an assassin. He had a natural talent to kill. It was just simply that. Not to mention the fact that he was good friends with one of the most dangerous assassins ever, 27. 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." I DO NOT OWN KHR AND ASSASSINATION CLASSROOM.

Tsuna got send to Class 3-E. He has to inevestigate on them and decide, if the Vongola-Famiglia will try to kill Koro-sensei too. Its my first real english-story (the others are only short stories with 120 words in my english classes). Please don't mind grammar or spelling mistakes and if you want you can help me with my grammar and my spelling, so I can get better for the story. Thanks to all readers. I do NOT own KHR or AssassinationClassroom. I just own the idea behind this crossover.

Tsuna gets sent to class 3-E! Let's see how his presence helps them on their mission! Will Koro-Sensei die or will he live on? Will the class discover Tsuna's position? And let's not forget the Vongola and all their craziness! "Hiiiieee!! Reborn! What do you mean I'm transferring to another school?!" ( Set after Arcobaleno Battles and at the start of Assassination Classroom) Disclaimer: I do not own Katekyo Hitman Reborn or Assassination Classroom *Please go easy on me since this is the first fanfiction I've ever written. Comments are welcome. Arigato! NOTICE: I sincerely thank all of you readers for supporting this story but I have bad news. This story shall henceforth be on hiatus. I may come back to this story someday, but it's looking unlikely. My utmost apologies.

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.

Warning: Cursing, Yaoi, all things you call sexual, and...Reborn. A cliché story of a class trip to Italy? Not quite! Sawada Tsunayoshi, soon to be the official head of Vongola, faces something that may be the cause of him backing down on taking such an 'honorable' job. Don't worry! He has a list...a looooong one. What does it take to be a mafia boss? Well, perhaps coping with fangirls, his insane and spartan tutor that still wants to make his life miserable, a genius stalker, a yellow octopus...and his certain red-haired student can possibly let him be at peace? This'll probably take more than his dying will.

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?

Right after the moon incident: Tsuna was transferred to Kunugigaoka with the help of his father and Reborn, his brother's (Giotto) tutor because they want him to get better. That's what they said, but the truth is, they just don't want him getting in the way of their work. Tsuna knew they were lying so he just followed them. [FULL SUMMARY INSIDE]

Sawada Tsunayoshi after 2 years of in a comatose state, finally awake. It seems that this Tsunayoshi is having a amnesia. Tsuna is in Class 3-E, because he is falling 2 grades. E for End. At Kunugigaoka Junior High School. When Tsuna came back, it is the same time as the new teacher arrives, replacing the death former 3-E teacher, Yukimura-sensei. But no one knows that she is dead. Tsuna's guardian, Yamamoto Takeshi, Gokudera Hayato, and Chrome Dokuro suddenly transfer to 3-E and exclaim that they are Tsuna's friend. Tsuna remember their names and face, but only that. The other guardians are transfered too, but not as a student. As a fellow assassin. What will happen? Will Tsuna remember everything? Or Tsuna only remember them, his power, and everything from his body? *** I do not OWN KHR and Assassination Classroom Warning! Beware of grammartical error!
