The Daily Life of a Legendary Assassin in the Academy

A legendary phantom assassin in the mainland accidentally encountered a miracle while defecting from the organization. He was reborn when he was ten years old. From then on, he began a happy daily story of practicing magic in a magic school while participating in the surging undercurrents on the mainland, and teasing and teasing his senior sisters in his spare time. (I also hope that this book will pay tribute to the eternal classic "Hidden Killing" in my heart)
