Kinako works at the Yumihariyu public bath house in the 24th Ward. Her deep respect for Ran Akagi led her to join the artist collective DoRed, assisting their operations and participating in their graffiti-based artistic expressions. During the SARG raid on DoRed's base, Kinako's absence meant she avoided public identification and subsequent arrest or targeting. To protect her, the rest of DoRed deliberately withheld their new hiding place, placing her safety above her involvement in their activities at that time.
