So I don't know how you'd feel about slice of life or journal-based games but if you're okay with those I've got route_29 as an offer for Tsubaki or Blair. Yes there's power loss but in exchange you get Pokemon and a medium-paced game that is incredibly backtag friendly and has fun plots (like right now there's going to be a prom and the last event was a swarm of Goomies [though nobody knows that they're Goomies yet so they're some ~mystery~ new Pokemon]). It is NOT a huge game despite what its reputation apparently is and there's a ton of wiggle room to do whatever you want as long as the mods don't think the boundaries are crossed.

Also not being up to date on the Pokemon or even not knowing about Pokemon doesn't matter that much tbh since all the characters in-game are more than happy to exposition dump about what they know so far.

We've only got Maka (played by me) and Kirikou there right now so, um, yes thanks for your time bye
