BTOOOM!

Ryouta Sakamoto is an unemployed young man living with his mother, known mainly for being Japan’s top-ranked player of the online game Btooom! That quiet routine shatters when he wakes up on a remote island with no memory of how he arrived—only a small green crystal embedded in his left hand and the unsettling sense that the rules of his favorite game have followed him into reality.

Given a supply of specialized bombs called “BIM,” each participant is forced into a lethal contest: kill seven other players, collect their green crystals, and earn a chance to return home. Ryouta, who recoils from violence, is pushed into fighting as he learns many competitors are far more dangerous than they first appear. Joining forces with Himiko, another Btooom! player, he struggles to survive and escape while closing in on the truth behind the island’s deadly game.
