Kyouhei Tachibana is a dedicated culinary student with expertise in French, Chinese, Italian, and Japanese cuisine. Often seen in his chef uniform and riding a small motor scooter—though it's destroyed by Jo on two separate occasions—Kyouhei is hired by Sei to cook for the girls after their previous cook leaves. Despite the chaos that surrounds him, he remains focused on his goal of saving enough money to travel to France and fulfill his dream of becoming a pastry chef.
