It is as per profile provided by Kisa-sensei in his latest art work.
Hm. Didn't know that one, but looks interesting. I didn't expect the purple color on her bangs, but royal blue on her twintails is pretty much what I expected going by her given name. Also the black based color theme fits her family name. Though I have to say that how she's depicted there makes me wonder about her character.
When I look at this artwork, I'm quite intrigued so see Ruri making that kind of grimace and gesture. Speaking of those, it's kinda nice how the hand gestures are aligned with their respective ranks. Miku looks adorable and that gesture seems as if she wants to remind us who is the boss at the academy. And Miss Number 2? Whoa... that's a cheerful Aya if she ever made one. Quite refreshing when you think about her usual poker face. And then Ruri. She seems to have a naturally hollow gaze and those dark bags under her eyes make her look a bit, well unhealthy. At least she doesn't appear like an honor student at all (Aya called her that)... I have to say, Number 4 gives off a rather strange vibe there.
I hope she will be an entertaining character.
