2. Sakura Kyoko (Sakura Kyoko): In "Battle of the Date", Sakura Kyoko was a very green tea girl who always used other people's feelings to satisfy her own needs. Her actions and words were very annoying.
3. Sanjiu Nakano (Sanjiu Nakano): In <<Full Time Master>>, Sanjiu Nakano is a very selfish and arrogant girl who always thinks that she is taller and better than others. Her actions and words often made people feel disgusted.
