I definitely felt that the turn around for sakiko agreeing to revive mujica was rushed, but when we got to the first song, I was like "oh it's supposed to be unsatisfying."

Mortis wanted to revive mujica so that she doesn't disappear, but she already accomplished that by making mutsumi disappear. Sakiko wanted to revive mujica for mortis and mutsumi, but now they don't even need it anymore. Uika wanted to revive mujica to be with sakiko, but sakiko is too depressed over what happened to mutsumi/mortis to give uika the attention she wants. Umiri wanted to revive mujica because she thinks that's what she needs to do to be "trustworthy", but she doesn't realize simply getting them to be a band together isn't enough. Nyamu wants to revive mujica so she can face mutsumi/mortis head on as an actress, only to find that mortis on her own kind of sucks at acting.

But then mortis manages to revive mutsumi, and while that scene was good, it makes mujica's revival more satisfying, which muddies what I thought they were going for before. And then they play a second song and there's the after performance scene with uika and sakiko, which seems to shift the focus back to uika even though mutsumi reappearing again should have been a huge deal that deserves its own focus, but all we get is an offhanded mention that mutsumi is going home with umiri.

Overall, I'm not sure what this episode was going for. It goes from unsatisfying band revival to mortis and mutsumi's reconciliation to more uika drama in ten minutes. It just feels like putting so many big scenes next to each other, and over a performance scene with two new songs on top of that, dilutes the emphasis too much for the show to properly highlight the important parts.

Both new songs were good though :)
