Hibiki and Kanade can not get their hearts in sync and soon drop out of their transformation, letting the Negatone run rampage. As Hummy inquires over why the two don't get along, Hibiki reveals that she was waiting for Kanade by a cherry blossom tree on the opening ceremony of school, but she never came. Kanade has a similar story, and when the two come across a child in the same situation, they realise the reason they didn't see each other was because they went to opposite sides of the school. With their confusion cleared up, the two manage to face off against the Negatone and defeat it, allowing Hummy to purify it back into a Note and keep it safe.
