i don't wanna be a killjoy but if you're playing pokemon arceus please take the time to learn about the ainu people, their ongoing struggle to keep their culture alive, and the colonisation of hokkaido (the area the sinnoh region is based on)
the game itself has a good bit of colonialist themes and indigenous erasure, which means it's up to fans to educate themselves and be mindful of what things they internalise. this isn't a call out or guilt trip, i'm just asking people to be aware of the context behind the media they consume.
additionally, consider boosting ainu voices (especially about the game itself), donating to ainu individuals, and spreading awareness on the subject as allies.
