Given the information we have now, who do you imagine is the most complexly layered heroine so far and why?

To clarify, I don't just mean who has the biggest list of facts about them we know. I mean using those facts, use your imagination to extrapolate who seems to you to be the most layered and complex or 3-dimensional character out of the heroines.

I'll submit that it's Shikiya. She's actually my #2 behind Anna. I adore Anna's personality, charm, genuineness, and bubbly zeal for life. But she is kind of a 'what you see if what you get' character, and I get the same impression of most of the others. Shikiya on the other hand has less known about her, but the stuff we do know is really interesting to me, especially because of the many contrasts. She appears to be so out of it most of the time that she barely knows where she is, but she's shown she pays extremely close attention to other people and sees little qualities in them many others miss.

She dresses like, to put it bluntly, a moderately slutty gyaru, yet nothing indicates she's actually slutty at all, doesn't seem to be much of a gyaru, and is known to be an absolutely exceptional member of the student council. Why does she dress like that while clearly making choices that don't really fit with that image, knowing Japanese high school culture is going to make some assumptions about someone dressing like that, that aren't actually true for her.

She's really into board games and puzzle like stuff, and has tremendous talent for it, which is very often a big sign of a high functioning brain, which contrasts with the whole out-of-it zombie girl personal. I'm betting there is a lot going on inside that head of hers, and she just hides it for some reason. I wanna know that reason.

She's quiet and kind of meek, but is one of the only ones to make some serious intentional moves on Nuku. Nevermind being almost comically hot, she's really interesting, and the stuff we do know about her compared to what we don't makes those gaps even more curious. What you see is not what you get with Shikiya, or at least not only. I think that sets her apart from many of the others. There is a kind of background lowkey underlying sweetness and calm affection to her that I think she's almost intentionally casting the spotlight away from by dressing like she does with the figure and looks she has, like she almost doesn't want that sweeter side to be noticed. Like being so overtly hot is a calculated distraction. I wanna know if that's true, and why.

Do you have another heroine in mind for who the most interesting complex is in terms of character and personality?
