Amagami SS EP23 - Ayatsuji Tsukasa Arc, Chapter 3: Pride

With the festival behind schedule and Tsukasa's health worrying her, Miss Takahashi suggests they cancel some events, but Tsukasa assures her the festival will be ready unchanged. Knowing that the festival committee is short of manpower, Junichi manages to convince Tsukasa to get their class to help. However, a trio of girls complain and accuses Junichi and Tsukasa's flirting with each other as the root of the festival’s problems. When she fails to end the argument nicely, Tsukasa switches to her real personality and cites the trio’s hypocrisy, silencing and shocking everyone. Later, Tsukasa brings Junichi to the shrine again where she burns her notebook, makes him promise to be hers and seals the deal with a kiss. The next day at PE class, Tsukasa is ganged up by the trio again in dodgeball but the rest of class sides with her, forcing the trio to give up. However at noon, only Masayoshi, Keiko, and Kaoru remains to help Junichi and Tsukasa.
