He was abandoned when he was a child because he didn't have a mark, meaning that he is unable to use magic. Regro Burnedead found him and raised him like a father outside the big city, hiding Mash from society and teaching him auto-defense. They lived a peaceful life until one day Mash goes to the city and a policeman discovers him. After that event, Brad Coleman notices that Mash doesn't have a mark and goes to Mash's house to find him. Once there, Brad hurts Regro and after an "intense" fight with Mash, they accord that Mash will go to the magic school in order to maintain their peaceful life. Mash agrees and, in that process, Mash set his goal to become a Divine Visionary.
Mash is of average height and has got a muscular build. He has black bowl-cut hair and a fake mark made by Brad Coleman. When at Easton, he wears the standard white shirt, black trousers, red tie, brown shoes and black cape. When away from school, he often wears white shorts, and black under armor.
Mash is generally quiet and kind. 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 almost every situation.
He is also very blunt and says things that would be rude to others, without a care in the world. He also firmly believes in his abilities so much so he downright told the headmaster he would "knock the stuffing out of [him]" with his fist.
Iron Wand: Mash's "wand" is an extremely heavy rod. According to a wand shop owner, not in a thousand years has anyone with strength or Magic, been able to lift it. Mash is able to forcibly change the shape of his wand with his incredible strength. The wand is sturdy enough to withstand Mash's inhuman strength and its mass seems to increase depending on the shape it takes.
Wrist Weights: Mash is constantly wearing magic wrist weights to limit his strength. According to his foster father Regro, Mash's muscles went out of control, which is why he told him to never take them off.
Cream Puffs: Mash always carries cream puffs, his favorite food, on his person.
