Name: Kingusuri Hitsujikai
Age: 16
Personality: Fairly calm, good at giving advice, extremely patient, dark on both outside and inside, fairly blunt, usually quiet, and if you somehow manage to break his patience than he'll be filled with homicidal rage and use his explosive magic on you.
Appearance: Shaggy, white hair that goes halfway down his neck. Bright, fiery, orange, catlike eyes. Pale skin. Skinny, tall form. A somewhat demanding presence comes from him at all times except when he's giving advice, with a loved one, or trying (and succeeding) to blast your face off. And a long, thin scar going from just below his left eye to about 5 inches below the collar bone. Always wears a long white lab coat, black athletic pants, a black t-shirt, and some adidas shoes. Also wears a pair of golden knuckles with knife-like points at the tips. Several concealed knives with golden handles and solid steel blades thinner than 2,000 picometers (100 picometers is about the length of a hydrogen atom). Wears solid steel platings just below the surface of the skin so they're undetectable and they're also what causes his skin to be so pale. Fingernails are pointed just enough to draw blood but are relatively short.
Scientist or test subject: Famous aspiring scientist born in Japan. (Not actually Japanese)
