Kana is a magician who escaped the laboratory with Kuroha and is her roommate. Kana is paralyzed and cannot talk without her keyboard and has good intentions though she can be quite mouthy and rude. She has the ability to predict how and when people are going to die.
It is revealed later that if the third button on her neck is pressed, she will be able to move freely, but she will lose her power to predict death. The reason why she was able to endure all kinds of inconveniences brought by paralyzation was because Kuroha saved her life once, and she would devote her power to help Kuroha whenever possible.
When Kuroha was facing Valkyria, Kana predicted Kuroha's death and got her third button pressed to help Kuroha in person. She successfully killed Valkyria with a surprise attack, but Valkyria regenerated immediately. Ever since Valkyria's been defeated, Kana remains her current state and is able to move freely.
