Toshinori Watanabe (Edens Zero TV 2, Fairy Tail: 100 Years Quest, Tokyo Ghoul:re) is directing the anime at Studio DEEN. Keiichirō Ōchi (The Quintessential Quintuplets, Summer Pockets, Go, Go, Loser Ranger!) is overseeing the series scripts, and Tokuyuki Matsutake (Dimension W, Genocidal Organ) is designing the characters.
Kodansha USA Publishing is releasing the manga digitally in English, and it describes the story:
Since before the dawn of memory, one thing has defined human history: the war between ninjas and yakuzas. This coarse and manly manga follows two members of these warring tribes who fill the gutters of modern Tokyo with blood to determine which elemental force will reign supreme!
Kondō launched the manga in Kodansha’s Comic Days website in January 2020. Kodansha will publish the manga’s 15th compiled book volume on May 14. Kodansha USA Publishing will release the seventh volume in English on May 13.
