[Crossing Star Academy, I relied on knowledge to become a forbidden curse mage] —— Raphael was transported to the magical world and became a gentle and polite new student at Star Academy. He just wants to hang out in the library and study the nature of magic, and has no interest in fighting for hegemony or falling in love.
