Crunchyroll’s Supernatural Mystery Keeps Getting Darker Every Episode

by

Season 3 of the series started streaming on Crunchyroll in January 2026, covering the Mainstay and Scandal story arcs. From this point forward, the manga by Aka Akasaka and Mengo Yokoyari explores much more serious themes as Aqua Hoshino pursues her revenge and Ruby Hoshino strives for success as an idol, marking a shift in tone from the first two seasons.

The series Oshi no Ko begins with a unique premise: a doctor and his patient are reborn as the twin children of a popular singer. However, the story quickly becomes darker as these children grapple with the adult memories and trauma trapped inside their young bodies, impacting their relationships and choices. If you haven’t started watching yet, now is the perfect time – things are about to get intensely difficult for them.

Oshi no Ko’s Reincarnation Premise Fuels a Revenge Thriller That Escalates Every Arc

Aka Akasaka intentionally developed the reincarnation idea in Oshi no Ko to be a core element of the story, not just a temporary plot device. Aqua Hoshino’s memories from his previous life as Dr. Gorou Amamiya provide him with the mental strength to skillfully control the entertainment world. This allows his plan to get revenge on Hikaru Kamiki to be carefully calculated and deliberate, rather than a rash reaction to his mother’s death.

Ruby, formerly known as Sarina Tendoji, is determined to rebuild the idol group B-Komachi—the group her sister Ai used to be a part of—instead of seeking revenge. Ai had always encouraged Ruby to dance, even when she was very young and struggling. However, Ruby’s hopeful attitude clashes with Aqua’s desire for revenge, creating tension between them. Things become even more complicated when Ruby discovers the same person was responsible for the deaths of both her mother and her doctor from her past life, giving her and Aqua a shared goal but increasing the conflict.

The first episode of Oshi no Ko opens with the shocking murder of Ai Hoshino by a stalker who felt ignored by her. This 90-minute premiere earned a high rating of 9.38/10 on MyAnimeList. As the story unfolds, the pain of her death only intensifies, as it becomes clear that Hikaru Kamiki was secretly pulling the strings behind the entire tragedy.

Watching this series, it became clear it wasn’t just a revenge story – it was constantly building to something bigger. The reveal that Hikaru Kamiki wasn’t focused only on Ai, but was a long-term predator who targeted young actresses – marking them with white flowers before committing murders, including poor Yura Katayose – was shocking. Then, when Aqua discovered his own father had orchestrated Ai Hoshino’s death, the whole world of the entertainment industry became the backdrop for a dark and twisted crime. It really shifted the focus to the industry itself being the crime scene.

Oshi no Ko Season 3 Breaks Its Own Characters in Ways Earlier Seasons Only Hinted At

In Season 3 of Oshi no Ko, Aqua Hoshino’s deep emotional distance becomes a major issue, leading to a confrontation with MEM-cho about his avoidance of Kana Arima. She reveals his fear that loving someone will ultimately lead to their destruction. The season also dramatically impacts Kana, undoing the progress she made in the previous seasons as both her feelings for Aqua and her career with B-Komachi fall apart at the same time.

Kana’s emotional breakdown is especially impactful because she’s already overcome huge setbacks – she was a child actress who lost her career, fought her way back, and then lost it all again. During the scandal storyline, Aqua reveals Ai’s secret to save Kana, essentially exchanging one scandal for another and prioritizing Kana’s life. However, Ruby disagrees with Aqua’s methods, causing a rift between the two siblings.

Season 3 of Oshi no Ko marks a significant and darker shift for Ruby Hoshino, especially following her confrontation with Aqua about Ai’s scandal. She stops being the heart of the B-Komachi group and starts using deception – just like her mother did – to succeed in the entertainment world, all while she tries to uncover a hidden truth.

The doctor who treated her was also Aqua’s former identity, a discovery that will significantly increase the tension as it’s revealed. As Ruby’s condition worsens, she starts behaving in ways that even Aqua, a character known for making difficult choices, finds troubling.

Oshi no Ko Turns Japan’s Idol Industry Into a Horror Story With Real-World Parallels

I’m completely fascinated by how Oshi no Ko connects everything! The show brilliantly reveals how the ‘no dating’ rule actually caused Ai to hide her pregnancy as a teen, and that secrecy was the perfect setup for Hikaru Kamiki to manipulate and ultimately harm her. And it’s not just dramatic storytelling – Akane’s storyline, with her near-suicide after being cyberbullied on LoveForReal, feels incredibly real because it’s sadly based on actual events within the Japanese entertainment world. It’s powerful because the show builds its intense drama on documented social issues, not just made-up melodrama.

MEM-cho gave up her dream of becoming an idol to care for her mother and brothers. To continue working in the industry, which often favors younger women, she had to pretend to be younger than she actually was. Her captivating, star-shaped eyes were a key part of her appeal, allowing her to convincingly portray emotions on stage – a talent that fueled her success but also contributed to her downfall.

Both Aqua and Ruby Hoshino received a piece of their mother’s talent, and the story of Oshi no Ko follows how they slowly learn to use lies as a tool, just like their mother Ai did. The series shows that the entertainment industry is deeply flawed, and even someone like Akane can be affected by this corruption, as demonstrated when she briefly gained a similar ability to Ai by perfectly imitating her.

Aka Akasaka and Doga Kobo Engineered Oshi no Ko’s Escalating Darkness by Design

Initially, Aka Akasaka hadn’t intended for Ai to die. However, as he was writing Oshi no Ko, he realized Ai Hoshino was outshining the twin protagonists. This led him to make the difficult decision to kill her off, turning it into a central, intentional plot point. Given that Oshi no Ko and Akasaka’s other work, Kaguya-sama: Love Is War, exist in the same fictional universe, the entertainment world of Oshi no Ko is a darker, more cynical reflection of the brighter world he created in Kaguya-sama.

Mengo Yokoyari, known for creating Scum’s Wish, brings a similar artistic style to Oshi no Ko, focusing on how people manipulate each other and unhealthy close relationships. The anime seemed destined for popularity from the start, evidenced by its opening theme, “Idol” by Yoasobi, which topped the Billboard Japan Hot 100 for three weeks. The song’s cheerful sound hides darker hints of what’s to come, just like the show itself, which often lures viewers in with one expectation before surprising them with something else.
