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. There, the sphere gives them special suits and weapons, and sends them out on a mission to kill aliens here on Earth. While these missions take place, the rest of the world is largely oblivious to them. These missions are lethal - few participants survive them. The sphere calls the shots, and it\'s not the slightest bit nice. Its name... Gantz.
Prequel to 2004 coming-of-age live-action film Hana & Alice. After her parents separate, 14 year-old Tetsuko (who will soon be nick-named Alice) moves with her mother to a new town in what she calls \"The Boonies\" and must enroll as a transfer student in a new middle school. She immediately finds herself bullied due being assigned the seat of \"Judas\" who is said to have been murdered over a year before. She is told that if anybody knows his fate it would be Hana, the recluse in the house next door, who has been unable to bring herself to attend class since \"Judas\" disappeared.
