I think maybe the app could be good? Chie's great at fighting, but writing fight scenes has never been my forte tbh.

And... hm. Chie's just coming to terms with her romantic feelings for her bff Yukiko, so maybe something about feelings for people who aren't there? Another thing she's having to deal with is guilt for doing so much Anime Comedy Violence at her friend Yosuke in her canon which she's been realizing was pretty shitty to do, so something about hurting people could also be cool?
