📖 SYNOPSIS
Gorou is a rural gynecologist with one guilty pleasure: he's a devoted fan of teenage pop idol Ai Hoshino. When fate puts him in charge of secretly delivering Ai's twins, things take a sharp turn: Gorou is murdered by a stalker, only to wake up reincarnated as one of Ai's newborn children, Aquamarine, with all his adult memories intact. His twin sister Ruby, it turns out, has her own past life and connection to his previous one. That's the setup, and it all unfolds in a jaw-dropping first episode that runs feature-length at 90 minutes.
From there, Oshi no Ko peels back the glossy surface of Japan's entertainment industry — idol culture, reality TV, social media pile-ons, the machinery that chews people up behind the scenes. Doga Kobo's animation nails the contrast between the sparkle of stage performances and the quiet ugliness lurking underneath. The tone shifts between genuine warmth and something much colder without warning, and that tension is what makes it stick with you.
If you liked the psychological unraveling of fame in Perfect Blue, or the way Re:Zero uses reincarnation as more than just a gimmick, this hits similar nerves but from a completely different angle. There's also a melancholy running through it that fans of Your Lie in April will recognize. It's an 11-episode TV series adapted from a seinen manga, and that first episode alone is worth your evening.
