A pair of high school students, Kei Kurono and Masaru Kato, are hit by a subway train in an attempt to save the life of a homeless drunk who had fallen onto the tracks. Following their deaths, Kurono and Kato find themselves transported to the interior of an unfurnished Tokyo apartment. The pair soon realize others are present and find that they are not able to leave the apartment. At one end of the room there is a featureless black sphere known as "Gantz".

After some time in the room, the Gantz sphere opens up, revealing a bald naked man with a breathing mask and wires attached to his head, and three racks protruding from it, that offer various items for them to use. These include the custom fitting black suits Gantz makes for each of them, giving them super-human abilities, a controller which acts as a radar and stealth unit, and three types of guns.

Kei Kurono has not been a contender in any CBUB matches.
