Kurono Yuuichirou

As the top-ranking director of Haijima Industries' development division, Kurono Yuuichirou is regarded as a combatant on par with Shinmon Benimaru. He takes undisguised pride in tormenting those weaker than himself, treating brutal experimentation and violent confrontation alike as nothing more than routine business matters. His right arm, carbonized by the Ash Disease, grants him the ability to wield lethal black smoke in battle. Despite being widely considered the most unhinged individual around, he demonstrates a remarkable sense of duty when it comes to his role as protector of the Sixth Pillar, Nataku.
