Jiro Hotta

Jiro Hotta is an adult man with an average constitution. Physically, he is very similar to his brother Ichiro, with dark hair, sharp eyes with small pupils, a goatee, and a small bump in the middle of his forehead. In addition to clothing, Jiro differs from his brother in that his face is a bit more slim square, and has a mustache.

When he makes use of his Quirk, normally after injecting Trigger, Jiro transforms into a humanoid grasshopper. His muscle mass increases and some parts are protected by insect-like quinine exoskeletons. His head resembles that of a grasshopper, with jaws, antennae, and compound eyes. Under this appearance, he is indistinguishable from his brother.

One way to differentiate him from his brother Ichiro is in the clothes he wears. Jiro wears a white hoodie and dark pants. Both brothers wear an apron with the name of their store written on it, and a yellow bandanna tied around their neck. The bandanna is the only garment that doesn't tear apart every time they transform.
