Yoshiki and Hikaru have been inseparable since childhood in their quiet rural town, until one winter Hikaru disappears and returns—only not quite himself. An otherworldly entity has taken Hikaru’s form, memory, and mannerisms, leaving Yoshiki trapped between grief and an unsettling new reality. As strange supernatural events unfold and others grow suspicious, Yoshiki must confront his fear and longing while confronting truths about identity and loss. The anime adaptation brings a chilling blend of coming‑of‑age drama and cosmic horror, directed by Ryōhei Takeshita at CygamesPictures. Premiering on July 6, 2025, and streaming exclusively on Netflix, this series explores what it means to hold on when the person you knew is gone.
