Souichirou Mishima

The owner of a famous restaurant chain and Miyabi used to work in one of his restaurants. At the beginning of the story, he was a businessman focusing on maximizing profits, such as instructing his managers to reduce stocks of wine in the restaurants and buy from nearby liquor stores when customers place orders instead. Mishima is a good friend to Shizuku and Miyabi, lending them a hand from time-to-time and serves as another confidant to them, and they also helps him in return. (Source: Wikipedia)
