Shin Ikki Tousen began in the fall of 2015 in Young King Ours magazine and has four volumes released so far in print.
Shonen Gahosha revealed in July 2021 that Yuji Shiozaki’s long-running overall project with the current incarnation of Shin Ikki Tousen will be getting a new anime adaptation on AT-X in Japan.
When they do, however, it’ll be for audiences in North America, Central America, South America, Europe, Africa, Oceania, the Middle East, and CIS.
