After a sudden accident, Chishu Lian transmigrated to an unfamiliar world, returning to the body of a seven-year-old. He had lost every memory except his name, and was adopted by Celestia. He grew up in this world and eventually enrolled at Canterlot High School, run by Celestia. He thought his life would carry on like that, until the appearance of a girl beneath a statue and a little purple dog. Chishu Lian once again felt the call of the light and recovered his memories. Now he would fight to save this world.
