Is it Gantz?
Sounds like Gantz, yup!
Thanks, that is the one =) I did not think anyone would answer so quick
Gantz is one of those truly great classic mangas that everyone should read if only to have a reaction to it! hehe
There is an anime of this too - but it's rather disturbing (I could only watch two before I quit watching)
Some time ago I was reading a horror in which the maincharacter against his wills gets pulled into saving a drunk man from being run over by a train, while the man is saved, our MC along withanother person seemingly dies (sort off??) as the two instead are transported into a room along with other characters who should have died.
So is there someone who can remember a manga like that?
