Bleach's representation has always been one of its strong points. It was one of the first mainstream anime to really lean into positive POC representation via characters like Yoruichi, Tousen and Zommari. (Using Spanish for a lot of the hollow stuff definitely helped its popularity in LATAM countries as well.)

Speaking of Zommari - a lot of people forget that queer and POC villains can still be positive representation if they're (a) not exclusively villains and (b) simply allowed to be cool and menacing, both in terms of abilities and just interesting character design. And if there's one thing Kubo can do in his sleep, it's great character design.
