What is Playing Sister?
Playing Sister is a supernatural thriller that unfolds across three episodes as an original net animation, launching on January 31, 2026. The story centers on Akane Higure, a middle school student in the isolated Kagami Village, who becomes caught between a cryptic folk legend about Doubles and a disturbing revelation about the person who has just returned home claiming to be her sister. The series blends mystery and psychological tension as it explores what happens when familiar figures become strangers, grounded in the eerie atmosphere of a remote community disconnected from the modern world's rapid technological advancement.
The ONA format allows the story to unfold in a condensed narrative experience rather than spread across a traditional seasonal run. With only three episodes comprising the complete story, Playing Sister delivers a contained thriller that prioritizes atmosphere and psychological unease over extended plot development. This winter 2026 release suits viewers seeking short-form anime that combine supernatural horror with genuine mystery rather than relying on jump scares or gore.
In the distant future, on the outskirts left behind by the rapid concentration of advanced science and technology in urban areas, lies a remote mountain village known as Kagami Village. “Behave yourself, or a Double will come for you.” Such old folklore still lingers in this village. Akane Higure, a middle school student living in Kagami Village, has been eagerly awaiting the return of her older sister, Sui Higure, who is finally being discharged from the hospital after a year. However, not long after her sister comes home, Akane receives a single phone call. “The girl at home with you… isn’t your sister.”
