I probably wanted to write a story where the main character is a Chinese boy who amuses himself by traveling around various schools in order to escape from the pink robe of a Japanese magic institute.
Protagonist: Male
Non-wizarding, Muggle
Enrolled in the only magic academy in Asia - Japan Magic Institute
I have a grandfather who cultivates immortality, and his dream is to become a handsome magical boy.
(Grandpa: We have a traitor among us)
Note:
Poor writing
I only watched the movies and never read the novels
The settings are all determined by checking the wiki, there may be errors.
