I'm Chinese American and proud of my heritage even though I'm out of touch with it as an adult living away from family. Still, I always try to slip in some Cantonese rep when I find the right spots in my stories!
My stories with Asian protagonists
Tula who is Filipina
Ian who is Chinese
Jeff, also Chinese
Helen is half Korean
Then while not a main character, Billy is pretty important in Sarota Springs. He's Japanese.
And then you can find side characters that are Asian in my stories Heavy Horns and Secunda.
LOL I've basically listed all my stories, but there's one more that I have on Tapas. No Asian rep there but then again it's just a short zine about Greek monsters.
