Dumb character names make it impossible to write fic for this game

why is the headmaster’s first name literally just the japanese word for headmaster. how are other characters supposed to refer to him. “mr.” sounds too western for a fic set in japan, shuyona-kouchou just sounds like his name, and kocho-kouchou is absolutely out of the question. google said that “sensei” isnt typically used for headmasters but i swear im about to brush that off and use it anyway 💀
