Is Oshi no Ko Overrated? An 11-Episode Prestige Package That Rides a 90-Minute Premiere and a YOASOBI Single to Numbers It Doesn't Earn

Oshi no Ko posts a Codex 7.70 against MyAnimeList's 8.53 — a 0.83-point gap explained by a crowd rewarding the premiere and the OP, not the eight episodes in between.

The best 90 minutes of Oshi no Ko are its first 90 minutes, and the show has been living off that credit ever since. Doga Kobo's 2023 adaptation of Aka Akasaka's manga scores 7.70 on the Codex rubric against 8.53 on MyAnimeList — a 0.83 gap that is not a rounding error and not a taste dispute. It is the sound of a crowd scoring a premiere event and a Billboard chart entry as if they were an eleven-episode season.

The Consensus Is Scoring a Trailer

The question "is Oshi no Ko overrated" reads, on MyAnimeList's 8.53, as heresy. That number puts the show in the neighborhood of series with tighter plotting, deeper casts, and finales that exist. It is a score built on two events: the feature-length premiere, which was screened theatrically in Japan in March 2023 before the TV broadcast, and "Idol" by YOASOBI, which topped Billboard Global Excluding US and became the show's de facto ambassador to viewers who never watched episode two.

The Codex rubric departs from the crowd not by disputing that the premiere is excellent — it is — but by refusing to let a 90-minute opener and an OP absorb the pacing collapse of episodes two through eleven. This is the same structural problem the rubric flagged on Your Lie in April, where animation and themes carried a story the crowd was already emotionally pre-committed to. Oshi no Ko is doing the same trick, in seinen drag.

The Premiere Is a Trap

The 90-minute first episode is a masterclass in setup. Ai Hoshino's murder pivots a reincarnation-into-idol-world premise into a revenge thriller, and everything preceding the pivot is retroactively reframed. Ai's monologue on the meaning of "love" — the thesis that fabricated affection can become real — is the single strongest piece of writing in the season, and Doga Kobo stages her concert sequences and the tonal drop into her death with the kind of restraint the studio rarely gets credit for. The story criterion sits at 7.5 largely because this episode drags the average up.

Then the show has to be a show. The reality dating segment and the 2.5D stage play adaptation that follow are competent industry exposés — the mechanics of reality TV editing, the pipeline from manga to stage, the manipulation of narrative persona — but they are not the revenge thriller the premiere promised. Aqua's investigation into the twins' father stalls. The mystery hook is deliberately withheld across an eleven-episode runtime that cannot afford the delay. What the crowd rewards as "slow-burn pacing," the rubric reads as a season built to sell a second season.

Aqua and Ruby Are Functions, Not People

Character scores 7.0, and the number is generous to two of the three leads. Ai Hoshino is the standout despite dying in the premiere — her limited screen time is loaded with more interiority than Aqua and Ruby accumulate across the remaining ten episodes combined. Aquamarine Hoshino is cold-revenge machinery, emotionally opaque in a way the show mistakes for depth. Ruby Hoshino's idol aspiration is a thematic mirror to Ai rather than a lived arc. Both twins operate as instruments the plot needs, not as people the plot happens to.

The exception is Akane, whose reality-show arc — the deconstruction and rebuild of a persona to survive an online mob — is the season's strongest sustained piece of character writing. It is also the arc most clearly informed by real-world tragedy in the Japanese entertainment industry, and it is where the show's parasocial thesis lands with actual weight rather than gestured intent. That Akane, a supporting character, produces the season's best writing while Aqua stays a revenge automaton is not a compliment to the ensemble structure. It is a diagnosis.

The World-Building Is Doing the Work the Story Won't

World scores 8.5, and this is where the show genuinely earns its reputation. Grafting a reincarnation revenge thriller onto an insider view of the Japanese entertainment industry is a legitimately original seinen premise, and the setting depth — idol production economics, reality TV editing as fiction, 2.5D stage adaptation logistics, the manga-to-anime pipeline — is rendered with a specificity most shows in the genre don't attempt. The star-pupil reincarnation conceit is aesthetic rather than systemic, but it functions as a visual shorthand for performance authenticity that Doga Kobo uses cleverly throughout.

The problem is that world-building at 8.5 and themes at 8.0 are propping up story at 7.5 and character at 7.0. A show whose setting is more developed than its protagonist is a show the rubric can identify by profile alone.

Animation Is Solid; the OP Is Doing Overtime

Doga Kobo delivers the polished, expressive character animation the studio is known for, and the star-pupil motif is a real piece of visual language. But animation scores 8.0, not higher, because the premiere is the technical high point and later episodes settle into competent, conventional staging. The show leans on "Idol" — its opening, not its direction — to carry stylistic identity across weeks when the storyboards aren't doing distinctive work. When the OP is your most-cited visual, animation is not what's carrying you; a single song is.

The Cultural Score Is the Rubric's Concession

Cultural scores 9.0, and this is where the Codex meets the crowd. "Idol" was a global chart phenomenon. The premiere event screenings were treated as a major theatrical release. Oshi no Ko drove a legitimate mainstream conversation about parasocial fandom and idol-industry ethics — reach that exceeds typical seinen ceilings. The rubric credits this fully. What it will not do is let a 9.0 on cultural weight and an 8.5 on world drag story and character above what the writing supports.

The Steelman

The strongest defense of the 8.53 is that Oshi no Ko is a first cour, that the manga's payoff comes later, and that judging eleven episodes against a completed narrative is unfair. This is a real argument. It is also the argument that props up half of MyAnimeList's top 100 — the assumption that future material will retroactively vindicate current pacing. The rubric doesn't grade on projected potential. It grades what aired. Eleven episodes that stall a revenge plot after a stunning premiere, resolve one supporting character's arc well, and end on withheld information are what the Codex is scoring. If season two closes the gap, season two gets scored. This one is 7.70.

Verdict

Oshi no Ko is a genuinely original premise executed brilliantly for 90 minutes and competently for eight more, wrapped in a cultural moment its writing does not sustain. The 0.83-point gap between crowd and rubric is not the crowd being wrong about the premiere or the OP — those are as good as advertised. It is the crowd refusing to notice what happens between them.
