Even though I'm a sucker for WWII stuff, I think the coolest organization might be the Iscariots. All of their members are so unique in their own way, and I like how it depicts the intensity, so to say, of some roman catholics. Especially the whole "killing for god" thing. Very interesting!
Whats your favorite organization? Hellsing, Millenium or Iscariot? I promise I won't judge if you say Millenium. XP
