Naoto Shirogame

We first meet Naoto shortly after we meet Kanji. Kanji is being investigated and Naoto causes Kanji to question his sexuality. Kanji dosen't need to worry though, because Naoto, despite looking exactly like Kou, is a girl. Naoto struggles with the fact that she is a detective, a 16-year-old, and a girl in an occupation full of men. This is probably best represented by her shadow boss, a half-human half-cyborg toy to represent how they "take her out of the toy box" to let her work a case, and she does well, but as soon as it's over, she goes back in the toybox. Back to being just a child who can't be trusetd to do police work (despite being the best in the area, and Yu would know, he has three detective social links.)
