And You Thought There is Never a Girl Online?: Ako is strictly Rusian-sexual. He shows no interest in women who do not have these parts. The manga Ai Kora appears to be this series' main plot, as the main character Hachibei Maeda only finds attraction in women who have his "Ideal Parts". All of the other Elites are asexual except for him who develops lust and then love for Riki. However, Iason is quite literally Riki-sexual. Guy and Iason from Ai no Kusabi are this for Riki. Especially applicable in that Keiichi was once gender-flipped into a woman, and Belldandy didn't care a whit (except caring in that Keichii himself was somewhat dismayed). Belldandy of Ah!

Not even porn can do it for Alice unless Bob is in the porn. She can only be attracted to/aroused by him not even other men, or, for that matter, women. Alice has never really been in love with anyone else but Bob.
