(Shiunji-ke no Kodomo-tachi) is a romantic comedy anime centered around Arata Shiunji and his six siblings — Banri, Seiha, Ouka, Minami, Shion, and Kotono — who live together in a prestigious household in Tokyo’s Seijō neighborhood.
The story takes a dramatic turn when their father reveals that none of the siblings are biologically related. This revelation shatters their understanding of family and opens the door to unexpected emotional shifts. While the siblings initially promise to maintain their familial bonds, romantic tensions begin to surface — especially as several sisters start expressing feelings for Arata that go beyond sibling affection.
Arata, who values their connection and wants to preserve the family dynamic, must navigate this complicated new reality while protecting the unity of the Shiunji household. The series blends humor, awkward romance, and heartfelt moments, exploring themes of identity, love, and what truly defines a family.
Want help turning this into a character breakdown or adapting the dynamic into a community roleplay concept for Respawn Otaku? I’ve got ideas ready to go.
There is a Season 2 in the works I will update when it releases
