A dudebro anime, that's Oshi no ko. No depth, no premise, just a bunch of bug eyed teenage girls with no personality.
Though the first episode was interesting, the rest was a free fall to garbage land. We were promised a story of revenge, a chase to uncover the truth, but all we got instead was superficial teenage melodrama. No offense to anyone who enjoys that, however it is decidedly not my cup of tea.
The characters were super boring. Noting but generic and cliche sob stories narrated again and again with the hope that repetition would make them sympathetic.
Not worth watching, I'd like to get back the few hours spent on this dumpster fire of an anime. Alas, lost time is never found again.
If you're looking for a brainless eye candy anime then this is definitely for you, though that's all it amounts to.
