I just checked Kirsches Twitter page, and one of the first things I saw was her posting links to download some hentai of herself. IMO, she's not really helping her case here considering the fact that in the past she has complained about people seeing Vtubers purely as coomerbait and those people having the opinion that most Vtuber fans are just porn addicts who want to jerk off to the avatar. She also said multiple times that she doesn't really like coomers and porn in general, but then proceeds to post links to literal porn of herself. Maybe I'm retarded for having this opinion, but saying you don't like coomers and porn but at the same time pandering to coomers by posting this shit is kinda retarded.
Edit: Also, a Josh and Kirsche collab would never happen in the first place, but when Josh sees this shit I don't think this will have a positive impact on his opinion about her.
