Personality[]
Mafuyu has the behavior of a stereotypical teenager, particularly those from Generation Z. He is a very vocal germaphobe, going to extreme lengths to avoid dirty things and reacting with incredible disgust whenever he gets dirty. He won't even use his hands in battle due to not wanting them to get filthy, opting to use blades hidden inside his shoes to fight.
Unlike Shin, he isn’t much of a cinephile and doesn’t have the patience for watching movies, preferring to see the reviews about them from Vtubers, earning him the ire of Kanaguri.
Despite his quirks, Mafuyu can remain incredibly calm in the heat of battle and even when faced with death. He is also shown to be timid and appears to see other people like Shin as influences quite easily, despite insulting him with names like 'old man' at first.
