Fifteen-year-old Sawada Tsunayoshi was replaced. His companions, his family, his glory, everything about him was replaced by 'her'. Who still remembers who is their tenth generation, the leader of the Vongola family.
Eighteen-year-old Sawada Tsunayoshi lives an ordinary life as an ordinary college student. But one day he was sent to the future by Garcafis, which was a twisted ten years later.
Ten years later, the future was distorted by Mary Sue and was about to collapse. Gakafis could only send Sawada Tsunayoshi to save the world again.
All27, everyone in the future dotes on Tsuna very much and won't let him touch him at all. Everyone has a dark side and they don't dare to show it in front of Tsuna.
The author has something to say: The characters in the novel are seriously OOC and cannot be tolerated. I like everyone in Tutoring, so I am writing a novel. I hope you won't say you hate anyone when the time comes. After all, Tutor Killer is a good anime.
