If they don't, then it'll be subject to terrible editing, no matter where it airs. I mean, it's not really suitable for normal Toonami, unless they edit the fanservicy things out (like Viletta's boobs D:), and they'd take out some of the explosions and shit, due to 'terrorism' scaring people and people being too sensitive to things like this.

Adult Swim is really the only place it wouldn't be completely butchered, really, though it still isn't the best place, either. Cartoon Network is really the only network that shows anime anymore, so it's either Adult Swim or Toonami, and I'd much rather have Adult Swim air it unedited than Toonami butcher it.
