Taigai

An assassin serving under Takeru Shinoyama. He belongs to the assassin clan known as Black Thunder. When he encountered Koyū Azuma, who had been exiled from the clan, he mocked him, which led the enraged Bao to steal all of his savings and transfer them into Koyū Azuma’s account. He is a battle maniac, described by Bao as having less reason than a beast, and is solely interested in fighting strong opponents.
