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. Mafuyu can remain incredibly calm in the heat of battle and even when faced with death.
