shark girl is genuinely a great mix of being cute, shitpost gremlin, and mixing up stuff like karaoke singing with her other stuff, so I can see why she's popular,
I think you'd appreciate Mori (the shinigami's) personality but she is the MOST focused on her non-gaming stuff (well, okay, Ina is equally focused on art)
I might drop Hana Macchia, her collab stuff with Pikamee was great but she spends a lot of time like fishing and playing genshin impact and doing Indonesian-language free talk streams
Allow me to advocate for eldritch tentacle god - she's a pro artist and super chill, her streams all have a very calming aura, she does gesture drawing streams so viewers who are inspired to work on their own art can practice along
She reminds people to stretch and hydrate, she makes many terrible puns, she has one brain cell (Amelia is the only one who claims to have multiple, hence being a genius detective) so uses her tentacles and chat as backups
shinigami girl's vocie is.... very good.... /swoon etc
-phoenix girl and shinigami girl are yeah what he just said dammit
