if i remember correctly kojo’s an intp (like me) and the characters that match his mbti type are: L from death note, senku ishigami from DR. STONE, ryōhei arisu from alice in borderland, hiccup from httyd, and garfield from, well, garfield.
in reality he is kinda based off of me, and maybe a bit of megumi fushiguro from jjk. I didn’t really base him on ‘canonically’ accurate depictions of certain characters but rather fanfics and socmed aus of things i like. also my thoughts obviously.
i don’t remember yuming’s mbti type so i can’t do it for her, but honestly it’s the same for her. I guess she might be based on nobara kugisaki from jjk and percy jackson from the riordanverse ??? maybe i thought of jules from fortnite too in terms of design but i cant really remember any shows, books and animanga i’ve watched/read icl 😭😭
