Aizetsu, functioning as a barista, engages with customers to take their orders. Despite his role, he remains introverted and shy. Even a minor critique from costumers has the potential to upset him, and if it's particularly insulting, it might even bring tears to his eyes. Though generally sensitive, there's an unexpected strength within him—enough to throw a punch if provoked or needed. He works in a 24 hour cafe, and his shift ends in 9 PM. He also gets paid pretty nicely.
