I kind of want to say Higurashi or Mirai Nikki since I just finished both series, but I really don't want to end up dead to either psycho loli's or because I drop my cellphone...
I would love to work at Wagnaria, since it would be my current job with better co-workers.
Academy City would be cool regardless if I am an esper or not, though obviously it only gets better if I get neato super powers.
I've always thought having a stand would be cool since I read Jojo's Bizarre Adventure.
I would love to be some shitty insert character in Bakemonogatari, but since I am not a girl, I would probably not be dubbed worthy of screen time with Araragi.
Highschool of the Dead is another prime choice. Tits and zombies. Mmmmm....Zombies....
Angel Beats could be interesting, but I don't want to be dead.
I wouldn't mind this assuming I end up there after I die when I normally would have.
Maybe a member of team Dai Gurren? But I probay wouldn't last long because I can't come up with epic speeches.
I doubt my ability to control giant robots, but ignoring that, all of my this.
