The official X (Twitter) account of the supernatural horror manga The Summer Hikaru Died (Hikaru ga Shinda Natsu) has announced that the series by Mokumokuren will officially end after just 2 more chapters.
Release schedule for the final two chapters
According to the official announcement, chapter 50 will be released on October 13, 2026, and chapter 51, the final chapter of the entire series, will arrive exactly one week later, on October 20, 2026.
Five years on Young Ace Up
The Summer Hikaru Died began serialization on Kadokawa Shoten's Young Ace Up platform in August 2021. As of June 2026 it has been collected into 9 tankobon volumes, building a loyal following thanks to its suffocating horror atmosphere set in rural Japan and the story of the friendship between Yoshiki and the "thing" that took the place of his late best friend Hikaru.
Why is it so highly regarded among horror manga? Most horror manga rely on jump scares or grotesque monsters, but The Summer Hikaru Died takes a psychological route: the dread comes from the protagonist continuing to stay with the "thing" wearing his friend's form even though he knows the truth, raising questions about the line between affection, loneliness and the fear of loss. This slow, suffocating approach is often hard to translate fully to animation, so having season 2 handled by the same studio that made season 1 helps keep the work's distinctive atmosphere consistent.
Anime season 2 confirmed, no air date yet
On the anime side, season 2 was confirmed on September 27, 2025, right after episode 12 of the first season aired, with CygamesPictures continuing production. As of now, however, neither the official air date nor the episode count for season 2 has been announced.
- Chapter 50: October 13, 2026
- Chapter 51 (final chapter): October 20, 2026
- Author: Mokumokuren
- Serialization: Young Ace Up (Kadokawa Shoten)
- Volumes released: 9 tankobon (as of June 2026)
- Anime season 2: confirmed, studio CygamesPictures, no air date yet
OtaHub's take
Wrapping up the whole storyline in just 2 chapters is fairly surprising for a long-running psychological horror series like this, especially while the second anime season hasn't aired yet. It may be a deliberate decision by Mokumokuren to keep the story tight and not stretch it longer than necessary, a problem many other psychological horror manga have run into when trying to sustain tension over too many chapters. With anime season 2 confirmed but not yet scheduled, viewers will likely read the manga's complete ending before the adaptation catches up with the story.
