>>13703075I remeber reading an interview to one of the animators who stated that, yes, the female companions were in the anime for the sole purpose of being eye candy (you can dress them differently for more varied reasons, and you can put them in skimpy dresses and swimsuits.
But I think this factor wasn't fully used with Iris. Oh, what I would give to see her with her hair down in the anime, or with a swimsuit that had a bare belly.
