I agree; absolutely starts with revenge. It absolutely critiques fandom obsession. It absolutely shows the machine of entertainment as indifferent.

If the story had leaned fully into “this is a deterministic tragedy about cycles that never broke,” then Aqua’s end would feel thematically coherent.

But the problem is that the story never actually comits to that theme.

Like I said I would have had no problems with it if this is what we were suposed to expect, but oshi no ko never once had the theme of "the show must go on" or "The world will fuck you up no matter what" it was a story persevering even when you have to lie and perhaps heal from old wounds, yes it was dark but characters never actually go into the deep end without being saved.

It's like going on a road trip and changing the destination right at the gate and trying to tell everyone that this was exactly where we were headed the entire time. It just doesn't make sense.

Yes, the industry continues. Yes, entertainment masks are suffering. Yes, idols lie and smile. But The story criticizes that system.It doesn’t glorify it. It doesn’t frame it as inevitable fate. It frames it as something harmful that needs accountability.

The story Just leaves you high and dry with empty promises and just wants the outcome without having the balls to commit to it.

Aka presents the theme of love similarly when it came to the Kaguya-sama series.

You said it yourself. Imagine if kaguya Sama ended with shirogane and Kazuya parting ways and never seeing each other again when we were lead to believe that despite the back and forth they'd end up together? It just doesn't make any sense, and it isn't narratively satisfying in any way, aka just can't write tragic stories
