Aoi Matsumoto

Matsumuto Aoi is the owner of the Warring States Themed Bar. Matsumuto Aoi usually has an indifferent look on his face. When he is working at the Warring States Themed Bar, he ties the front part of his hair out so that his side bangs come out more. Matsumuto Aoi lied to Daiki about an available part time job was tutoring, but it was actually a part time job as Hall Kitchen Staff at the Warring States Themed Bar. Aoi wanted Daiki to work at the bar because he wanted a "tall commander". Matsumuto Aoi was able to get Daiki to work at the bar. (Source: Taiyou no Ie Wiki)
