I watched small chunks of Aikatsu a long time ago, so while I don't quite remember most of the characters I definitely get the vibe and Ran's perfect. I love this in concept.

And on that note, here's a bassist that has some minor trust issues and approximately zero self-worth, I bet they would get along. Lisa's getting back into music after setting it down for mental health reasons a couple years ago, and has a Unit with Ai Hoshino and Hibiki Tachibana to basically do music things in the Dream Sphere, but she also, uh. Needs friends. And would intimately understand where Ran's coming from with her approach to making connections. She's also been in Yumemigaoka her whole life and followed Dreamer news and popular teams, so she might recognize Ageha by description, even though Lisa herself's only been Dreamer Rhodonite for... almost two years now, aaaaa.
