Seriously? North Korean bands? *Laughs in Cake* North Korea only really has National songs that propagate the nation's agenda. Girl's Generation which you linked is from a band in South Korea. My favorite GG song too. Also the girl doesn't look anime like at all. Edit: Damn Defry edited his post!
Did I edit it? I don't think so. Anyways, it was obvious that I was referring as SK when saying Koreans. I doubt NK has anything related to that... poor souls, they are struggling to survive.
So you found a cosplay girl who also sings but that has nothing to do with anime. Pretty sure there are tons of cosplay girls. Belle Delphine, she's not the only one. https://www.instagram.com/just_ahega0/
yeah, there are others but their ahegao quality is low, mostly it looks like they are making derpy faces or they hit their toes Is like, ahegao requires charm, not only sluttiness
There's a dozen good ones, you just have to scroll, scroll, scroll... but then the older the posts get the more likely those accounts were deactivated(coz instagram is shit and blocks ero pics even when they're not porn). You could still search those deactivated accounts to see if they made new ones with similar names. There's mytivationcosplay,hana.mei.cosplay, kinechan 3.0, yanderejutsu,hheadshhot and more
