Ryouta Sakamoto is unemployed and lives with his mother, his only real achievement being that he is Japan's top player of the popular online video game Btooom! However, his peaceful life is about to change when he finds himself stranded on an island in the middle of nowhere, with a small green crystal embedded in his left hand and no memory of how he got there.

Armed with a bag full of unique bombs known as BIM, the players are tasked with killing seven of their fellow participants and taking their green crystals in order to return home.

Teaming up with Himiko, a fellow Btooom! player, they attempt to get off of the island together, coming closer and closer to the truth behind this contest of death.

They were supposed to be able to live forever—until the one called Luna died and the Ruin started. Their bodies will rust, and there is nothing that can be done to fix it. Now the robots are left only to contemplate their deaths, kept going only by the rumor that if they eat the one called Casshern, they will gain immortality. Casshern knows nothing about his past, why he exists, or what he is, but he must find out, or he will face the constant torment of being hunted by robots who don't want to die. Casshern leaves death wherever he goes, but he must face it if he is to find out the truth of this world.
