Hemo is the protagonist of takataka's Dragon With Horns series. He is a short wild boar alchemist and Takataka's self-insert, who suspiciously resembles the Pokémon pignite. He is an alchemist who specializes in concocting potions. He wears a black suit, a grey cape, and a black stetson hat with goggles on the brim. He carries a breathing mask, dagger, and utility belt.

Unlike most characters in the series, he does not quickly jump at the opportunity or try to solve all of his problems with sex. He also tends to be disturbed by the lewd antics of his partner in crime Arthur Draco
