The Summer Hikaru Died is approaching its planned conclusion, with creator Mokumokuren confirming that only two chapters remain. Chapter 50 is scheduled for 13 October, followed by Chapter 51 on 20 October.
The ending is not entirely unexpected. Mokumokuren had previously indicated an intention to complete the series across 10 volumes, a plan that now appears to be reaching its final stage.
A rural friendship at the centre of a supernatural mystery
The queer horror story follows Yoshiki Tsujinaka and Hikaru Indo, two boys living in rural Japan. Although their personalities differ, they are exceptionally close. That relationship changes after Yoshiki discovers that the Hikaru beside him is not truly his friend.
Hikaru died in a freak accident, and an unknowable entity from the mountain has taken control of his body. Yoshiki and the being wearing Hikaru’s face must then navigate an uneasy bond while investigating the disturbing secrets surrounding their isolated town.

Publication history and final volume outlook
Mokumokuren both writes and illustrates the manga. Serialization began on Young Ace Up on 31 August 2021, after the publication’s editorial department discovered the artist’s early concept drawings on Twitter.
Nine collected volumes have been released so far, covering the story through chapter 46.5. The five chapters still to come are expected to form the tenth and final volume. Yen Press has localised and distributed the series in North America, with the first seven volumes already available there. Volume eight is scheduled for release on 27 October.
As of June, the manga had reached 5 million copies in circulation. It has also received several award nominations, including recognition at the 2026 American Manga Awards.
What the Netflix anime adapted
The first anime season ran for 12 episodes on Netflix from 6 July 2025 to 28 September 2025. Cypic, the studio behind Umamusume: Cinderella Gray and Apocalypse Hotel, adapted the opening half of the manga.
The adaptation was praised for preserving the oppressive summer atmosphere and the story’s carefully observed relationships. Its horror is matched by a bittersweet emotional core, with themes of queer isolation and confronting stigma woven into the supernatural drama.
Cypic has already announced a second season. With the manga now nearing its conclusion, that follow-up is expected to adapt the remaining material, although the precise coverage has not been confirmed.
A series with a clear ending in sight
For readers and anime viewers who value horror built around character relationships, the final chapters will decide whether the story’s ambitious setup receives a satisfying conclusion. The manga’s planned 10-volume structure gives the ending a defined shape, while the anime still has the rest of the narrative to bring to the screen.
