Two men crawl out of Cambodia's killing fields with one promise to each other: build a sanctuary, no matter what it takes. They return to Japan and split into opposite worlds, one climbing through politics, one through yakuza syndicates, but they're not playing by anyone else's rules. Sanctuary is about what friendship costs when you've already lost everything, and how two people can stay loyal to each other while becoming unrecognizable to the rest of the world.

Two Japanese men survive the Khmer Rouge massacres in Cambodia and swear to find a sanctuary, building one themselves if they must. Back in Japan, Asami and Hojo choose paths that look like opposites: one works toward a career in politics, the other joins the yakuza. Moving through the connected worlds of government and crime, they will do whatever it takes to hold their ground and keep their vow, loyal to nobody but each other. As both climb higher, their friendship comes under growing strain. The single OVA is a tense action drama and thriller.
