The June issue of Akita Publishing’s Monthly Shōnen Champion magazine announced on Wednesday that Dōma Oda will launch a spinoff series of Yura Urushibara’s Tougen Anki: Dark Demon of Paradise manga titled Tougen Anki Gaiden: Tsuki to Sakura no Kyōsō Kyoku (Tougen Anki Side Story: The Rhapsody of the Moon and Cherry Blossoms) in the July issue on June 6.
The story will focus on the untold past of Tsukuyomi Momoka and Ousuke Momokado.
The Tougen Anki anime will premiere in July 2025.
REMOW describes the anime’s story:
“You inherit the blood of an Oni (demon)…”
The bloodlines of “Oni” and “Momotaro” have been passed down among certain humans for generations. Long ago, the Oni, aware of their own ferocity, lived in seclusion. However, their peace was shattered by an invasion led by Momotaro. Over thousands of years, these two factions formed the “Momotaro Agency” and the “Oni Agency,” respectively, and have been locked in conflict ever since.
The protagonist, Shiki Ichinose, suddenly learns of his Oni lineage following an unexpected attack by Momotaro. This revelation sets Shiki on a path to discover the destiny that lies within his blood — a meeting with the Oni dwelling within him.
— A new generation of dark heroics begins here in this tale of demons!
The series is receiving a game adaptation for mobile devices and PC by game developer Com2uS in 2025.
Urushibara launched the manga in Akita Publishing’s Weekly Shōnen Champion magazine in June 2020. The 23rd compiled book volume shipped on April 8. Yen Press began publishing the manga in English in September 2024, and will ship its third volume on May 27.
The manga previously inspired a stage play that ran Tokyo and Osaka in February 2024, and a sequel stage play ran in January 2025.
