I smiled while reading in your comment that you feel "feminization" is the stage just before "infantilization" and, if I dare say, "animalization"! Well, if we speak of the most conventional feminity, it's not completely wrong. And it's probably the reason why I loathe almost anything specifically feminine (but to say the truth I loathe as well a large part of what is supposed to be specifically masculine).

But this process is the topic; so, you have to accept it with the story. Personally, I don't see IK as feminine at all (actually I'd rather say he's totally alien to the feminine side of the world), while I could detect some feminine aspects in NS. And yet, I guess the choice of Napoleon for the victim wouldn't have worked here. And Illya is the ever suffering character in the show too. I don't think it's because he was set as the sidekick at the beginning. There is something else.
