Seven key facts at a glance, covering the show’s core stats and original context.

What is Oshi no Ko about anime?

What is the story of Oshi no Ko?

The series begins when a small-town doctor, Gorou Amemiya, and his terminally ill patient Sarina are murdered and reincarnated as the twin children of pop idol Ai Hoshino. They are reborn as Aqua and Ruby Hoshino, respectively. The first episode – a feature-length 90-minute premiere – sets up this supernatural premise before jumping into the twins’ teenage years, where they begin navigating the entertainment industry while Aqua secretly investigates the true circumstances of their mother’s death (Wikipedia – plot summary).

Who are the main characters?

• Ai Hoshino – The idol mother whose murder sets the plot in motion. A rising star with a dark secret.
• Aqua Hoshino – The reincarnated doctor, driven by a need to uncover the truth about Ai’s death.
• Ruby Hoshino – The reincarnated patient, who wants to become a famous idol like her mother.
• Kana Arima – A child actress who becomes a rival and friend to Ruby.
• Akane Kurokawa – A seasoned talent who gets entangled with Aqua’s plans.

Each character reflects a different face of the entertainment world: the dreamer, the manipulator, the survivor (MyAnimeList – character list).

The takeaway: Oshi no Ko uses its reincarnation premise to give its characters a dual perspective – they live through the industry both as insiders and as outsiders shaped by past lives. That double view is what makes the story’s critique of fame so sharp.

Is Oshi no Ko anime worth watching?

Why do some people dislike Oshi no Ko?

The show has been praised for its writing, voice acting, and emotional weight. On MyAnimeList it holds a score of 8.4/10, and on IMDb it holds 8.4/10 as well (IMDb – user ratings). But it’s not for everyone. Some viewers find the first episode’s slow, methodical pacing a barrier, and the heavy themes – suicide, murder, exploitation – can be off-putting for those expecting a lighter idol story (MyAnimeList – user reviews). The tonal whiplash from the idol introduction to the revenge mystery is deliberate but polarizing.

A Reddit user on r/AnimeRecommendations described it as “a very different kind of anime … it is a mystery drama that talks about the darkness of entertainment.” That darkness is exactly why some people bounce off it.

The trade-off: You get one of the most original narrative premises in recent anime, but you have to sit through emotional weight and deliberate pacing. For viewers who enjoy mystery and character drama over action, the payoff is worth it.

Is Oshi no Ko a romance anime?

No. While there are romantic subplots – Aqua’s complicated feelings for Kana and Akane, and Ruby’s childhood crush – the core genre is drama/mystery. The show’s Wikipedia genre listing classifies it as drama, supernatural, and slice of life. Romance takes a back seat to the revenge plot and the exploration of idol culture.

Is Oshi no Ko LGBTQ?

There is no explicit LGBTQ representation in the anime or manga. Some fans have interpreted certain character relationships – particularly the intense bond between Ruby and Kana – as having romantic undertones, but the creators have not confirmed any queer subtext. The show focuses on professional dynamics and personal trauma rather than sexual identity. For viewers seeking clear LGBTQ themes, this is not that show.

Why this matters: Calling Oshi no Ko a romance would set the wrong expectations. The emotional core is familial love, betrayal, and the cost of ambition – not romantic tension.

Why is Oshi no Ko not popular?

It’s not that Oshi no Ko is unpopular – it has a dedicated fanbase and strong critical scores. But it never reached the mainstream visibility of shonen giants like Demon Slayer or Attack on Titan. Several factors explain this:

• Genre hybrid – It doesn’t fit neatly into any one category, making it harder for algorithms and recommendation engines to place it.
• Dark tone – The heavy themes (murder, suicide, exploitation) limit its appeal to younger or casual audiences.
• Slow pacing – The first episode is a 90-minute movie that spends time building the world before the plot kicks in. Many viewers drop out before the twist.
• Not a battle shonen – Without constant action, it lacks the viral clip potential that drives series like Jujutsu Kaisen.

Nevertheless, it has a strong presence on platforms like Reddit and MyAnimeList, and its Rotten Tomatoes audience score remains very positive. It’s a cult hit rather than a mass-market one.

Why don’t people like Oshi no Ko?

Criticism usually centers on two points: the slow first half of the season, and the emotional gut-punches that some viewers find manipulative. A Reddit user on r/AnimeReccomendations put it: “It is a mystery drama that talks about the darkness of entertainment” – and that darkness is not for everyone. Others find the reincarnation premise hard to swallow, feeling it undermines the realism the show otherwise strives for.

The pattern: Oshi no Ko is a niche series that asks for emotional investment up front. For viewers who click with its tone, it’s a masterpiece. For those who don’t, it’s a slow, depressing show that feels like a bait-and-switch from its idol-themed initial marketing.

Is Oshi no Ko a sad ending?

Without spoiling major twists, the ending of Season 1 is undeniably bittersweet. The season concludes with a significant emotional event that redefines the characters’ motivations going forward. The tone is not happy – it’s contemplative and tinged with loss. For the full impact, we recommend watching through the final episode. The MyAnimeList reviews describe the finale as “emotional” and “unexpected.” If you’re sensitive to character death or emotional manipulation, be prepared.

What this means: The show doesn’t offer easy resolutions. It commits to its emotional stakes, and the ending of Season 1 sets up a larger mystery that will continue in Season 2.

Editor’s note: The appeal of Oshi no Ko lies in its refusal to be one thing. It’s an idol story that hates the idol machine, a reincarnation tale that stays grounded in human emotion, and a mystery that doesn’t rush to resolve. For fans of smart, emotionally mature anime, this is one of the best series of 2023. For viewers who want light entertainment or pure romance, it’s better to look elsewhere. The choice is clear: if you’re ready for a story that will make you think and feel deeply, Oshi no Ko delivers.
