The March 2018 issue of Shonengahosha’s Young King Ours GH magazine has published the last chapter of Isutoshi’s Aiki-S manga. The manga’s ninth and final compiled book volume is scheduled to be released in Japan in April 2018. The manga is a sequel to Isutoshi’s earlier Aiki manga.
Isutoshi published the original Aiki manga from 2004 to 2013, and then relaunched the manga under the title Aiki-S after ending the Eastern Europe arc. Shonengahosha published 14 compiled volumes of the original series, and published the eighth compiled book volume of Aiki-S in October 2017.
