Heiwa no Kuni no Shimazaki e

After surviving a terrorist incident as a child, Shingo Shimazaki was forced to join the League for Economic Liberations' revolutionary army. Now, thirty years later, he's back in Japan and trying to assimilate to a normal life. His Japanese may be awkward, and his grasp of ordinary tasks a little weak, but he has all the combat and surveillance training of a green beret. There are many kindhearted souls who want to help him - and a few not so kind ones who will do anything to stop him. (Source: Kodansha USA)
