第 11 集: 真誤解了絲的告白並遇見與他兄弟有關的怪物
Makoto misunderstands Silk's confession, thinking she is only cosplaying, and he asks if he can tak her picture when she's in costume. Tsubomi takes the opportunity to get the other girls to cosplay with her as the Ultimate Girls. Makoto finds out that Okamura is a dōjinshi collector who has collected a very large number of Ultimate Girl books and has a table reserved for the final day of Comike to sell a book of his own. Makoto is inspired by him and decided to become the ultimate Ultimate Girls collector. Suddenly, a new monster appears and defeats Tsubomi in one punch, but not before she notices that her brother, Makoto, is the core of the monster. Vivienne goes to fight the monster, but starts losing to it, too. Tsubomi tells Silk that the monster is her brother. (Source: Wikipedia)
