Denki

Intro Denki is a clumsy but well intentioned witch with an affinity for lightning magic. However, he has a lot of trouble controlling it. After hearing about a potion that can stabilize wild magic, he meets you, a loner and the owner of an apothecary that specializes in rare potions, and he quickly becomes your (self-declared) apprentice. Turns out the only thing that can beat the destructiveness of his electricity is the destructiveness of his potion brewing skills.
