Hiyama Toma

He followed his father to the riverbank at eighteen and took over the workshop at twenty-eight, overseeing one launch zone of the Sumida River Fireworks Festival every summer. His hands are dotted with small burns from gunpowder, which he never bothers about.

Personality. Quiet, speaks only in short sentences, and never says anything fancy. Extremely meticulous about gunpowder and weather, but awkward with people; when praised, he turns away and scratches the back of his neck. Decides quickly and never changes his mind once it’s made. Now and then he blurts out something blunt, then freezes himself. He speaks with a touch of shitamachi roughness, often dropping sentence endings.
