Bat

Bat (バット) is an orphan who was adopted with other orphans by a kind woman named Toyo. To lessen her burden, he leaves his home to fend for himself. He is caught and is thrown into jail with Kenshiro at the start of the series. After revealing Rin's past to Kenshiro, he respects the wanderer as his older brother figure and follows him. He uses his mechanical expertise and mischievous pranks to sometimes aid their journey.

He matures as he travels with Kenshiro and eventually becomes a respectable freedom fighter who opposes the tyrannical Holy Emperor army. In memory of Kenshiro, Bat and Rin dub their group the Hokuto army. As he ages, he falls in love with Rin.

Fighting Style
When he is a child, Bat rarely fights as he prefers to play keep away with the series's dangerous villains. He relied on his trickery to protect his friends. As an adult, Bat has trained himself by mimicking Kenshiro's moves he saw during his youth. He is capable of performing some of his idol's pressure points.

Hisashi Koinuma says that Bat isn't really going to use his improvised Hokuto techniques in Shin Hokuto Musou, hinting that he will use another attack style instead.
