>>12154083We haven't really seen selen's niche preyed on yet but we'd see her losing viewers if another girl debuted with many of the same appealing traits about her, which is what I think happened to Finana.
Enna and Millie were also cute small girls that sometimes have no filter and talk about sexual topics or jokes with gross shit.
Inna also makes funny voices like Finana. They're very different but they share some appeal as a demographic with members of the audience.
These girls have the advantage of being great singers too.
It's just hard competition for a similar niche.
