Chief Lion/History

Background
His history is unknown, but he was already the boss of the Shishigumi when Ibuki joined the group at age 18.

Meteor Festival arc
Chief Lion appears and stops the Shishigumi members from touching Haru, then tells them to leave the room. He apologizes to Haru for the members' behavior and asks her to strip all of her clothes to see if she's pure white, or he will strip her by force. When she's done, Chief approaches her and observes very closely all parts of her body, making her terrified and embarrassed. He claims that shaming the herbivores will be creating a deeper and richer flavor in the meat.

However, Haru suddenly stood up and kicked his walking stick, surprising Chief. She tells him that while he was bragging, she was writing her will in her head. And that he will have the worst dinner, as she is extremely calm and the meat won't taste good. Annoyed, Chief then says he was too soft on her, and that he will tenderize her now. As he was about to devour her, he got attacked and stopped by Legoshi.

Both of them started to fight, and at some point Chief dodged the wolf's punch and bit Legoshi's wrist. Later, Legoshi claims to end the fight already, which he agrees. Legoshi then dodged all of his attacks, jumped on him and bit Chief's nape and ripped it off, making him unconscious.

After Legoshi and Haru leave, Chief wakes up and went to the balcony and sees both of them leaving from behind. He noticed Legoshi missed his vitals on purpose and says that will teach him a lesson that "naive kindness will get you killed." He then aims the gun at him. But he got stopped by getting his arm shot from behind. He looks behind thinking it was Gohin, but it was actually Louis, who then aimed his gun into Chief's mouth.

Louis says he won't let Chief touch Haru ever again and ordered him to beg for his life, to show the face of a carnivore that is scared and to beg for forgiveness. As Chief was about to say it, Louis fired the gun in his mouth, killing him instantly.
