Kei Kusunoki’s historical dark fantasy manga, The Legend of Onikirimaru, is slated to end with its 23rd volume. This marks the end of a significant chapter in Kusunoki’s career, revisiting and expanding upon the themes of their earlier work, Onikirimaru (also known as Ogre Slayer). The final volume is scheduled to be released on June 24, 2025.
A Samurai’s Tale of Demons and Destiny
The Legend of Onikirimaru (Onikirimaru-den) is a manga series written and illustrated by Kei Kusunoki. It’s a sequel to Kusunoki’s earlier manga, Onikirimaru, and it’s set in the Sengoku era (the age of warring states) in Japan. The story follows a demon boy who, unlike other demons, lacks horns. He wields the cursed blade “Onikirimaru,” the only weapon capable of slaying demons, and is locked in a never-ending battle against the demonic forces that plague Japan during this tumultuous period.
Premise
Here’s a breakdown of the key elements:
- Setting: The Sengoku era, a period of intense internal conflict and political upheaval in Japanese history, serves as the backdrop. This era is known for its powerful samurai warlords, constant battles, and intricate political machinations.
- Protagonist: The main character is a demon boy born without horns, a symbol of his unique position between the human and demonic worlds.
- The Sword: Onikirimaru, the cursed blade, is not just a weapon but a symbol of the protagonist’s destiny. It’s the only thing that can kill demons, forcing him into a life of constant battle.
- Conflict: The manga explores the clash between the human world and the supernatural, with demons lurking behind the historical events and figures of the Sengoku era.
Echoes of History
The story weaves through the lives of famous historical figures such as Oda Nobunaga, Toyotomi Hidetsugu, and Ishida Mitsunari. The manga suggests that behind the well-known stories of these powerful generals lie secrets and demonic influences.
Unveiling the Past
The Legend of Onikirimaru also delves into the protagonist’s origins, exploring the secrets of his birth and the hidden aspects of his past. This adds a layer of mystery and personal stakes to the overarching conflict.

Kei Kusunoki launched The Legend of Onikirimaru in LEED Publishing’s Sengoku Bushou Retsuden magazine in 2013. The series later moved to Comic Ran Twins in 2016 after Sengoku Bushou Retsuden ceased publication. In 2018, the manga found a new home on the Pixiv Comic website. Crunchyroll Manga had previously published the manga digitally in English, but the service ended in December 2023.
