When our beloved mafia family had to transfer to another school, Tsuna thought he can live a peaceful life for a while . He was so wrong and he would never have his peaceful life even if he transfer to another school. Things get more complicated when Yamamoto decided to join the famous Karasuno High school volleyball club because the greatest hitman , Reborn would totally join the chaos and ruin his highschool life in Karasuno. Neither KHR nor Haikyuu are owned by me.

I know there is a lot of stories... or rather fanfic about Tsuna's class going to Italy during their class trip or being chose to go to visit there... But their reaction is priceless and funny to not write. It is interesting too! I wanna give it a try too. This is my first story so I'm sorry if there is too much spelling or grammer mistakes. English isn't one of my best subjects.. There is no pairings! And sorry if the characters are too OOC! You can comment it if you want about it, I might change it if I have time. The pictures are not mine! I do not own KHR too! I own the story plot only :3 Sorry if my description is bad! Reborn and friends are planning to get revenge for Tsuna. What could go wrong? But what if an enemy attacks when the students are in the Vongola Mansion?
