Okayu was really sick or she had broken something I can't remember which and she """had to""" wear diapers (but it implied she could've used the bathroom on her own) and said she used them several times. Okayu has told Subaru that she wanted to change her diaper
Lui has implied a couple times that she's into diapers or pee play but it was always vague
Korone once held her pee for so long she got a UTI and did it because holding her pee felt good
Gura asked Ame if she could put her in a diaper and it made Ame super uncomfortable.
Those are the only I can think of. Ame wet the bed once but she didn't imply that she liked it
