It's been 13 years since Reborn arrived to train Tsuna to become Vongola Decimo. Tsuna has settled into the position and has finally fulfilled Primo's wish of returning the Vongola to the way it was before Secendo took over. So when a small, weak famiglia comes to attack, Tsuna and his guardians think this will be a quick and easy battle. However, when Byakuran and the arcobaleno come to visit they are shocked to find the Vongola mansion destroyed and Tsuna and his guardians dying. What happened? Will Tsuna and the others survive? Read to find out I don't own KHR, it belongs to its rightful owner. This is my first fanfiction so if you have any pointers please tell me.
