Hanamori is the Koibuchi family's chauffeur and a childhood friend of Shu Koibuchi. He is a Mercedes-Benz enthusiast and easily caves under pressure, bribery, or requests from people with an afro. A smooth-talker who loves to flirt, he's more self-centered than not despite a solid streak of decency. He bears the distinction of being the only male allowed freely in and out of Amamizukan.
