Gantz/1

The start of probably one of the weirdest mangas/animes I've ever read/watched. The premise is that a couple of recently-dead people got sent to a room with a large black ball, which then proceeded to give them a mission that they must complete. The protagonists appear to be two highschool boys with contrasting personalities. They are both annoying annoying at times and flawed, but quite realistic - unlikely heroes in a way. Not particularly taken by the characters, but they are interesting enough. Gratuitous T&A and associated crude jokes/humour abound, so not recommended for people who don't like them. It's the premise that draws me in, though it's so outlandishly weird, it feels like it was purposefully so.
