Don't understand why DBZ characters are showing up, if it's supposed to be 200 years later. I mean, I can understand Piccolo, and maybe Goku (though that's a bit of a stretch--at the end of GT, when Pan was like 120 years old, Goku appeared just as he does throughout his adulthood--but GT is not mangabased), but Trunks?
Ah well. Continuity isn't important. Fanservice rocks.
Then again, the Player Character's name is 'HFIMM', perhaps that's an allusion to 'HFIL'. So maybe they're all in 'HFIL'. Then it would make sense...sort of.
