to be honest, as much as I love (and sexualize) them, I don't really think of them too much like this</3 I think I kind of give them more of a sisterly suspect, despite how much my art goes against that statement lol
the way I perceive them, no, but if she had successfully made komaru into somewhat of a "sex slave," then yeah ! kotoko could probably use her mindfucked or hopeless state to her advantage, especially since I hc her to be quite hypersexual ^_^
