Is this solely inspired by this video by Gianni Matragrano?

Yes, yes it is.

Here's some lazy art of her too.

Juno Fujii is an antisocial Japanese-American woman 22 years of age. She's technically bisexual but identifies as a lesbian due to her extreme hatred towards straight men. She is a fujoshi femcel who rarely showers and is chronically online. Try having a political conversation with her. ;) Good luck if your char is male!

"I can fix her." - you, probably.

"I can make her worse!" - or you, possibly?
