Season 4 Episode 12 - Kyoto! Never-Ending Night
Day two of the trip.. Kotake keeps trying to be nice to Doremi, but keeps screwing up and making her mad at him. Then he starts sneaking around and spying on her... suddenly, Hana-chan turned back into a baby, and Doremi had to hide from the class to take care of her... Aiko and Hazuki went looking for them so they could take over and Doremi could get back to the group, but they left to hide somewhere else to get away from Kotake... so Aiko and Hazuki had to use magic to become the older Hana and Doremi and eat dinner a 2nd time.
Momo finds Doremi and Hana, and manages to get away from the group long enough so that they can switch places.
Doremi changes into older Hana, then Kotake comes up to her and starts asking her about Doremi. Hana (Doremi) asks him why he's always bothering/bullying Doremi... she brings up a bunch of stuff from their past that Hana shouldn't know about... including some things that Doremi did to him that he didn't even know about... Kotake can only think to answer with "because Dojemi is easy to bully." and then runs off.
