32 years old. Pastry chef at the bakery "Antique". Former high school classmates with Tachibana. Tachibana was the object of Ono's first confession of love, as well as his first rejection. When the two next meet again, Ono has overcome this painful past and blossomed into a "gay of demonic charm" who is able to seduce any man he wants. Although he possesses impeccable taste and technique as a pastry chef of genius, his personal allure is always the cause of romantic trouble in the workplace, and he is fired from store after store until he finally settles in at the bakery "Antique".
