Anime and Manga Differences

  • Seiji talks to Yapool over his communicator instead of talking to Yuko Minami.
  • Edo is not seen in his human disguise.
  • The conversation between Seiji and Yapool is a lot less tense:
    • Seiji already knew who the perpetrators of the airplane incident were.
    • Yapool never reveals he made the Biological Weapons.
  • In the manga, Seiji talks to Yapool with an arm missing since Moroboshi sliced it off.
  • In the manga, Yapool never sees Edo standing in the street. Instead, he was in the interrogation room with the others, with Shinjiro being absent.
  • Moroboshi takes Yapool in after he runs over to the SSSP. This does not happen in the manga.
  • Bemular's conversation with Endo about the barcoded corpses is omitted.
  • The ending of Yapool's interrogation is slightly cut short.
  • In the manga, Shinjiro shows up slightly late to the raid on the house instead of being deployed together with Moroboshi.
  • The fight against Ace Killer starts differently. In the manga, Moroboshi uses a cloaking function and goes into the house alone, uncovering the storage of barcoded corpses in the process before the house explodes.
  • Alien Woovelve does not appear.
  • Ace Killer does not have a human disguise.
  • The eyes under Ace Killer's visor are never shown.
  • Ace Killer's footsoldiers never aim their laser sights at Shinjiro when they first appear.
  • The flashback scene with Seiji and Yuko is cut short.
