Gantz: Rebirth

What happens when you die? Do you go to Heaven? Maybe Hell? Does your spirit wander the earth? Are you reincarnated? Is it just darkness?

For former best friends Cole Everett and Donnie Ayers it was Gantz.

Cole and Donnie hadn't seen each other since grade school, but are reunited when they both start attending the same college. However, their reunion is shortly lived when they are caught in the middle of a convenience store robbery and killed, only to find themselves in an apartment with a group of strangers and a large mysterious black sphere at the end of the room, called Gantz.

What happens next... is up to him.
