Martin Mine studies at the Luna Maxima academy as a royal mage, and his teachers sometimes give him challenging tasks. For example, to come up with an appropriate punishment for a local prankster who, although entertaining at times, has become a nuisance.

At present, we know nothing about Martin's past outside of the academy. But we know that he lives in separate two-story apartments in the dormitory tower within the academy, he has no close human friends and only befriends a giant white snake that lives in the basement of the academy. Martin is quite rigid in moral questions, he almost always holds back his emotions. He is focused on achieving his goals and a bit inexperienced in matters of love and relationships, although he considers himself smart enough to figure it out without experience.
