Sign in to edit

The Summer Hikaru Died (光が死んだ夏, Hikaru ga Shinda Natsu) is a 2025 anime series based on the 2021 manga of the same name created by Mokumokuren. It was serialized and published in Kadokawa Shoten's Young Ace Up magazine on August 31, 2021.

It was produced by the studio CygamesPictures, directed by Ryōhei Takeshita, with scripts by Ryōhei Takeshita and music by Taro Umebayashi. The series premiered on July 6, 2025 and ran until September 28, 2025, consisting of 12 episodes.

On September 28, following the release of episode 12, a second season was announced.

The English dub of the first season was eventually released on Netflix on October 31, 2025.

Synopsis

Yoshiki and Hikaru have been together for as long as they can remember — their bond so deep it seems to have neither beginning nor end. In a small village surrounded by mountains, they shared laughter, routines, and quiet moments, as if nothing could ever break their connection. But beneath that calm, Yoshiki hides a secret: feelings that transcend friendship, desires silenced by fear and taboo.

Everything changes when a storm takes everything away. Hikaru returns, but something about him is no longer the same. To everyone else, nothing has happened; yet to Yoshiki, the truth is unbearable — the person before him is no longer entirely human.

Even so, clinging to that illusion becomes his only way not to lose him, even if it means deceiving himself, awakening shadows in the village, and facing truths that could shatter everything.

Will Yoshiki accept what he has lost... or will he sink into lies just to hold on to the one he loves, even if that being is no longer truly Hikaru?
