A lion wearing glasses, one of the three who first discovered the previous boss's death. Male, 35 years old. He is the one who suggested making Louis the boss. Feeling responsible for Louis becoming the boss because of his suggestion, he is the subordinate who treats and cares for Louis most like a true leader. Noticing that Louis is overexerting himself by insisting on a meat-only diet and refusing vegetables, he secretly buys salads and hands them to him away from other members. When another member mocked Louis, saying, "Once the Shishigumi stabilizes, we won't need him. How should we cook him at the end?", Ibuki got angry and said, "If you touch the boss, you'll be the one on the dinner table." He is said to be the top fighter within the Shishigumi. In Season 1, he stopped Haru's escape attempt with a precise dagger throw.
