On the anniversary of Tsumugi's mother Tae's death, Kōhei and Tsumugi try eating at an okonomiyaki restaurant, but Tsumugi gets upset when she doesn't get to do the mixing herself and has a tantrum. The gang gets together to make okonomiyaki that Tsumugi can enjoy, but Kotori is upset that her mother cancelled on her yet again. Tsumugi gets upset again after Yagi scolds her, though Kōhei talks to her and gets her to apologise. Kotori's mother, Megumi, shows up just in time, apologizing and introducing herself to everyone, and they have a happy dinner.
