Riki-Oh

力王

In the late 1990s, a decaying society on the brink of ecological collapse and totalitarianism serves as the backdrop. Saiga Riki-Oh, a 21-year-old man, finds himself incarcerated at the privately-owned Tokyo State Prison, serving a three-year sentence for assault.

Inside the brutal facility, control is held by a group known as The Four Emperors, powerful inmates who rule over the other prisoners. Marked by a mysterious six-pointed star on his fist, Riki-Oh becomes an immediate and open challenger to their oppressive regime, setting the stage for a violent and relentless conflict within the prison walls.
