Oshi no Ko arrived with a 90-minute premiere that shocked viewers: reincarnation, idol industry darkness, and murder mystery all in one episode. What followed maintained that ambition, delivering one of 2023’s most talked-about anime.
The Premise
A doctor reincarnates as the son of his favorite idol, Ai. His twin sister is a fellow reincarnate—a dying girl who loved the same idol. When Ai is murdered, both children enter the entertainment industry to find her killer. It’s simultaneously absurd and gripping.
The Idol Industry Critique
Oshi no Ko dissects entertainment industry toxicity: manufactured personas, parasocial relationships, exploitation of young talent, and the public’s entitlement to celebrities’ private lives. This critique has bite because Aka Akasaka clearly understands the industry.
Ai’s Tragedy
Ai’s story—an idol who couldn’t experience genuine love but desperately wanted to—grounds the critique emotionally. Her death isn’t just plot device; it’s the industry’s victim made specific.
Animation Excellence
Doga Kobo delivered career-best work. The premiere’s emotional devastation required precise acting animation. Performance sequences showcase idol choreography while maintaining character focus. The studio elevated already-strong material.
Music
YOASOBI’s “Idol” became a global phenomenon—one of the most streamed songs of 2023. It’s not just catchy; its lyrics capture Ai’s duality perfectly. The song represents anime music’s commercial potential.
Character Work
Aqua
The revenge-driven protagonist hiding behind entertainer facade. His adult mind in child’s body creates unique perspective, but his obsession threatens to consume him.
Ruby
The genuine idol aspirant who inherited Ai’s talent and curse. Her optimism contrasts Aqua’s darkness, creating sibling tension that drives emotional stakes.
Kana
The child actress whose career peaked early. Her insecurity about relevance in Ruby’s shadow adds industry realism—success is temporary, and falling hurts.
Verdict
9/10 – Oshi no Ko succeeds through ambition and execution. It tackles difficult themes without exploitation, entertains while critiquing entertainment, and features top-tier production. The ongoing mystery maintains tension while character work provides emotional investment.
