Mash is generally a quiet and kind boy who studies at Easton Magic Academy belonging to house Adler. However, if he sees someone hurting his family or friends, he gets incredibly angry.

He is also extremely innocent and obedient, making people abuse those qualities, but thanks to his strength he can twist out of almost every situation. Aside from his outright innocent thought process, he is incredibly blunt as he says things that would be considered rude to others, without a care in the world.
