Kana Kimishima

Kana is a disobedient "bad girl" who develops a crush on Shinichi. She is attracted to him because of his sensitive personality, and because she can sense something "different" about him.

~!In reality, Kana has an unexplained psychic ability to sense parasites. However, her senses are not as fine-tuned as those of the parasites themselves, and she cannot tell whether she is sensing the presence of Shinichi or of a normal parasite, putting her in considerable danger.!~
