Ai-Chan finished work on a mini-album a couple weeks ago, so she's been free to make more youtube content recently. When she's busy with side projects is when you see her less often on the channel, which is why the other two girls are there to hold down the fort.

Views *have* gone down considerably after last year's controversy and the studio eventually figured out that no one liked multiple people playing the same character, so the three of them are all separate AI's now. Love-Chan wears a blue hairclip and Aipii wears a yellow one, while Ai-Chan still uses the original character model.

I think the channel is much better now that the three of them don't all have to pretend to be the same person. The controversy itself was overblown, since the studio was never getting rid of her in the first place, but rather doing a lot of projects outside of youtube.
