Ep. 11: Yui and Iori revert to younger ages before Heartseed tasks Taichi with secrecy

On the eve of winter break, Yui and Iori temporarily revert to a younger age between 12pm and 5pm. They lose memory of the event but retain feelings from that time. That night, a second Heartseed appears through Taichi’s sister, instructing him to watch over the group and keep its existence secret. The following day, Taichi finds Yui arguing with old karate rival Chinatsu Mihashi over a forgotten promise. Later, Himeko and Yoshifumi shrink at an abandoned building. Ten-year-old Yoshifumi compares Yui to Nana Nishio, a former date, causing internal conflict regarding his feelings for both girls. After reverting to normal age, Yoshifumi explains Nana moved away. The next day, Taichi and Himeko watch over a 14-year-old Iori while Himeko expresses her concerns about the situation.
