Working!!

Synopsis

One of Souta's older sisters collapsed in front of Wagnaria, but he tries to keep the fact they are related from everyone else. Inami and Souma find out however, and Inami also finds out that Souta used to be dressed like a girl as a child. Souta pleads with her to keep both this and his sister from everyone else. Souta wonders what kind of person Souma is, and quickly realizes that he uses people's secrets to blackmail them to do his work for him, despite appearing to be cheerful. Due to a comment from Souma, Yachiyo asks Satou if he likes Kyouko, much to his annoyance. Souta later finds out that Souma is afraid of Inami and that he used to get punched a lot more before Souta started working at Wagnaria.
