星野 市香

She's a rookie cop who's been on the job for half a year, and works in the Special Regions Crime Prevention Office, more commonly known as SRCPO, in Shinjuku.

She's a strong-willed woman who tries to protect the citizens around her, and will always put the needs of others before her own. She's investigating the X-Day incidents because she believes it is key to unlocking the poison collar that was placed around her neck.
