Ikaros because she is the most beautiful angeloid/girl and also she is innocent and also learning to have free will. No matter what, its what she is, not about what she looks like. She is a good,gentle girl always preferring to end it peacefully. If she is violent, I doubt nymph would still be alive. Sorry to the nymph fan but it is true. Tomoki has done a good job teaching her and the result of that I support Ikaros.
Nymph, lol she has eyes and hair are blue, witch is my favorit color. that and she my be stubborn and have an attitude some times but damn!! she is cutie as hell. I so would ask her out if diberikan a chance.
