Wow Ayane as I-No...I honestly have to agree that it's a real out there choice.
But honestly, while Christie and I-No do have similar personalities, don't use Christie's DOA4 ending without context:
Christie's ending had her doing her job as an assassin, and female assassins DO use their feminine charms to make it easier for unsuspecting male targets to get killed easier by having them drop their guard.
Behind I-No's fanservicey actions is a pure bitch that would pretty much make her the proto-Terumi. She pretty much wrecked the True Timeline of Guilty Gear for shits and giggles(by having Ky go out of his way to save her...only to leave him hanging and let him die while talking shit), terrorized Dizzy to the point in a bad ending, she utterly snaps and kills her straight the fuck out among other things.
Hilariously enough, I-No's bitch levels actually does work with Ayane to that point.
