As Madoka and Ichika continue their battle. Tatenashi fights Squall on top of a tower at full combat. On a malfunctioning monorail that Chifuyu and the following students are trapped in, they deduce a time-bomb is attached to it, so Kanzashi quickly calculates the bomb’s whereabouts. As Ichika fights Madoka while reaching the train, Houki and Cecilia are attacked by Autumn and eventually rejoin Ichika, to see the train's explosion. Madoka kills Ichika by stabbing him, leaving Houki to save him and cries for his awakening. Luckily, Charlotte, Laura, Lingyin, and Kanzashi disarmed the bomb just in time. In a vision, Ichika is seized by Madoka, but then a mysterious girl in white hair gives Ichika a helping hand. Squall has the other IS pilots vulnerable, until Tatenashi diverts her with a weapon of hers and signals for Ichika to attack in White Knight form. Madoka intercepts Ichika. Ichika manages to strike her down. Phantom Task retreats for now and states they have collected enough data. Ichika is welcomed by everyone else alive and well. A scene is shown with Tabane sitting beside the white girl. In a hot spring, Ichika relaxes while thinking about Madoka's pendant that had Chifuyu's picture. Just before Ichika leaves the bath, the girls suddenly start coming in because a person accidentally changed the sign from male to female. This leaves all the girls embarrassed after seeing what is supposed to be Ichika, exhausted from the hot spring.
