This is a bit different from the previous challenge in that we know that the one to be eliminated will be one of the four (technically five) that we're being introduced to here will be eliminated. So I wonder who it will be? Like, Junna's obviously not going to be cut this round. (Even if that was Abi's plan) So the other choices are Mellow, Nei, Kasane, and Abi.
As much as I want it to be her and as hilarious as it would be if it was her, Abi's probably not going to be the one to be eliminated. The showcase of Nei's singing ability makes me think that she's probably not going to be eliminated, either, as this small group will give her a pretty good chance to show that off. And Mellow was in Junna's previous group, (as mentioned) so it feels a bit odd to shunt her permanently right after bringing her back.
So, via process of elimination... I guess Kasane's my bit for who'll be eliminated at the moment. Though at the moment I do think that it could be any of them. Things'll probably become more clear in the following chapters, though.
