>>295162I don't think there is much of a story. She used to post on /a/ and /jp/ looking to expand to english speaking audiences. Her kind of humor and content also fit well with 4chan so I think she was somewhat popular.
She's also got some historical worth for being one of the first Vtubers out there since before the term Vtuber was even coined.
She's now the producer/manager of a few other vtubers, Natsumi Moe being the only English-speaking one.
