>>23586701As far as I learned from Shiki's advice video and my observations, the agency isn't really responsible what their talents decide to produce. Of course there are some duties and expectations, but if you look at Ayame or Sana there's a lot freedom how often and what they publish. The opposite is probably Koyori from Holox who is a real content machine and collects money en masse. It's important to know, that the talents are not employed and are responsible to organize their content. The agency is providing some stuff they can ask for such as licenses, a studio, artists and so on. I guess it's a huge investment to produce an original song. I know from Baelz that she was deeply involved in writing the lyrics. It's probably not really paying off to have another original song. I guess the first one is subsidized by Cover, so their talents have a minimum standard. The same goes for Fubuki's costumes. I think she's just not investing much into more, because she thinks, she doesn't need more and now she's investing into a modernization of one of her designs. Of course, this is just speculation of how things could work and how decisions are made.
But doesn't Wakuwaku Everyday count? It's an original song by Fubuki and Mio. It was released in end of 2021. But it's somehow unclear to me why it cannot be found on their channels. What's the reason for that? Fubuki uses the song in her outro, it's catchy but it's not really promoted.
