A teen raised in the Netherlands by her single mother travels to their native Bosnia to visit the father who left them, as he’s been admitted to a rural hospital. Joined by her cousin and his best friend, they hit the road.

Somewhere in Tokyo, there is a room. In that room is a black sphere. Periodically, people who should otherwise have died are transferred to the room.

The sphere calls the shots, and it’s not the slightest bit nice. Its name… Gantz.
