Hiruma Gohei (比留間 伍兵衛) and his older brother, Hiruma Kihei, plot to take over Kamiya Kaoru's dojo. After her father died, Kihei collapsed in front of her dojo and she took him in. Kihei became kind of a live-in apprentice and kept asking her to sell her dojo. Gohei, a former samurai, became a murderer under the false name of Hitokiri Battōsai. When Kaoru begins to discover the truth, Kihei and Gohei try to kill her but Himura Kenshin saves Kaoru, beats Gohei and scares Kihei to unconsciousness.

Gohei requires a slightly raspy manly voice, try to be intimidating.
