If your'e into BL, Mother's Spirit is still one of my favourites.

Mermaid's Egg also has a good POC but the uke is trash and pretty racist (intentionally). It's enough to make me uncomfortable and I'm latina. Interesting world-building though.

Wish I could recommend some straight or GL manga. But the only straight manga I read is isekai and I have trouble finding GL that suits my tastes.
Fr!
All the GL I've remotely liked so far is on my GL Vetted By A Lesbian With A Weak Heart List. There's like...5.

If I read more I'm sure I'd find more to like, but we don't have something like Bara to isolate the lesbian-targeted stuff from the male-targeted stuff and I got zero patience for that. Would rather just trip and fall into the occasional GL
Dark skin, hair and eyes.
So when they gave her the symbol of light they chose to change her skin color instead of her hair or eyes. And nobody thought this was going to be a gross thing to do?
Lol.
I see what other people saying that it's what her skin color would have been without the blessing of darkness. But if the blessing of darkness changed her DNA then you have a 3rd parent in the gene pool. She was never white any way you swing it.
And keep in mind they could have changed her hair or eyes and the point would have been made.
I was so happy to see a dark-skinned isekai protagonist too. So sad.
