Sakura Megumi is a leading figure in Japanese manga "Isolated Island of College" and its derivative works. As a teacher of Takeya Yuki, Ebisuzawa Kurumi and Yuri of Wakayama. In fact, she died before Naoki Miki appeared, so Yuji has a regression phenomenon. In Yuji's eyes, Cijie still exists. Being called "Cijie" by the children, on the surface, she said "Call me Miss Shiori Sakura at school", but in fact she has accepted this title.
