Kōyū Shiki’s action, horror, and mystery manga series, Grand Metal Organs, has officially concluded its serialization. The final chapter brings an end to the dark, sci-fi narrative that began its run with Kodansha’s Comic Days in 2024.
The Story of Grand Metal Organs
Grand Metal Organs plunges readers into a world where electrical abilities define power and status. The protagonist, Enlil, is an outcast born without these powers, yet he dreams of joining the elite Electrical Police Department (EPD). His journey takes a dark turn when he uncovers a horrifying truth: those without power are not merely ignored, but actively “erased.”
Betrayed by a hero he once admired, Enlil is struck down. However, his story doesn’t end there. He awakens with a mysterious, dark power, returning not as a hero but as a “Dark Walker”—a nightmare figure seeking to save the world by destroying the corrupt system that rejected him. The manga has been praised for its quick pacing, compelling creature designs, and body horror themes.
Publication and English Release
The manga, originally titled Guran Metaruo Ruganzu (グランメタルオルガンズ) in Japan, was serialized in Kodansha’s Comic Days. Seven Seas Entertainment licensed the series for English publication, with the first volume slated for release in November 2025. This English release will be available in single volume editions, with ebook versions also provided on digital platforms.
The series has been listed with “Ongoing” status on several manga tracking sites up until recently, indicating its relatively recent conclusion. The final chapters were released over the past year, with the most recent being “c.3b” approximately seven months ago and “c.3a” eleven months ago, suggesting a gradual wrap-up to the story.
Kōyū Shiki’s Previous Works
Kōyū Shiki is known for his distinctive artistic style and contributions to the manga world. While Grand Metal Organs marks a recent conclusion, Shiki has other notable works. He is the artist for the manga adaptation of Fuyumi Ono’s horror novel Shiki, which was serialized in Shueisha’s Jump Square from December 2007 to June 2011. The Shiki manga also received an anime television series adaptation.
Fans of Kōyū Shiki’s work can look forward to completing their collection of Grand Metal Organs as the final volume becomes available, closing a chapter on this intense sci-fi horror narrative.
