Cure Muse +1

Cure Diamond -1

It was a tough choice between Cure Diamond and Cure Selene for the downvote, but I ultimately chose Cure Diamond because she doesn't really have a character arc. Every focus episode with her has a different thing she has to deal with instead of consistently dealing with one problem. Her debut episode has her feeling inferior to Cure Heart, but this isn't brought up again. Then, she's really into karuta, but she isn't seen being geeky again. Then, we have her relationship with Ira. The only consistent thing about her is her role as comic relief, and that isn't anything unique to Diamond.
