She is a magician who escaped with the other magic users and found a place to live with another Magic User named Chie. Due to running out of medicine and wanting Kotori to expierence her own birthday, Chie sacrificed her life so that Kotori could survive.
She first joins the astronomy club where her actions seem to be very hostile. However it is later proven that she is in fact a very kind and timid girl who always tries to put on a smile despite the situations in memory of her friend Chie.
Though timid and easily embarrassed, she is also friendly and willing to help others and her friends when she needs to. Much like Neko Kuroha, she is even willing to sacrifice her own life if it meant she could protect the life of someone else such as against her battle with Kikako and subsequently trying to hide herself away so that she could die and not risk using the medicine that others could have. It is only through the motivations of Neko and Ryouta that she allows herself the will to live again and continue on.
Kotori had a desire for drawing, often doodling during school work and drawing vague love scenes, something that Kazumi embarrassing called her out on.
It is later discovered that Vingulf is after her, apparently being a person of incredible danger that could potentially destroy the world if she isn't caught.
