If they stay in character forever their content is going to be kid oriented idol programming. If that's your thing fine but that's the same stuff that killed kizuna ai/mirai akari.
Shiori sperging in the big leagues is cool, she deserves it after so long.
Bijou is loli crap not interested.
narissa is the normie of the group a la mori/kronii which means shes the most functional probably but also the most e-thot-y
I don't watch EN regardless so I don't care. I'll listen to music they put out though.
Fuwamoco River City Girls sprite from HoloCure dev
Kay
Speaking of people finding success through years of work. Kay started out making mugen/game maker games like 15-20 years ago on two sites I cant currently show you cause the wayback machine is down, going by the name "StickOfDoom" (named after stick fight animations) before commiting 5 straight years to an
animation. Its basically just a recreation of the first episode of any shonen with terrible voice acting and embarassing writing. BUT, its got a amazingly well animated fight sequence half way through for a 1 man production. Having this on his portfolio got him his job at wayforward where he was the animation director for his first role in professional game development (river city girls) and he's worked on several real anime at this point (including naruto and SAO which he was already a huge fan of) as a result, holocure being his side project. Cool little success story there, I used to read/post on his forums and play his games/use his mugen characters so it's been neat seeing him find success doing what he enjoys rather than crying about it being too much work as a streamer like so many other animators.
Found one of his
sites. This isn't either of the two I was talking about though but it has working links to some of his games. He made at least 10 though theres only 3 here.
Also found this
video and
this one of people using one of his mugen characters and they perfectly embody early youtube.
