Hi I’m Asian (50%Japanese 25% Korean, and 25%Kazakh), and it’s not “cultural appropriation” and saying it is is pretty stupid. People with DID can’t pick their alters so 1: If they form an fictive alter from an anime they didn’t choose to have that fictive so therefore the name isn’t their fault. If you’re actually an introject you should know that and 2: People don’t pick their names. I know. Crazy. I lived in Japan for most of my life (I don’t now) and there used to be a white American transfer student in my class. Her real name was an American name but it was too hard to annunciate it, so everybody called her Sakura because her skin was kind of pink like a Sakura petal. You gonna say that’s cultural appropriation?
Plus, yeah that person will never be Japanese on the outside but just because they have a Japanese fictive doesn’t mean they are claiming to be Japanese. And 3: As a half Japanese person I’m happy people like our culture! I think that should be celebrated not bashed on.
Have a lovely day!
