Syoh's childhood friend and co-worker. She is 22 years old. She is a kind of partner who has always been involved in Syoh's resolution of the case. She sees the show as a reason, and she fights together to keep her promise with Syoh as a child. She likes sweets like cakes and fruzparpets and dislikes spicy kimchi.

She wore a ninja uniform and body stockings, and although she was short in height, she wore geta, so her judgment and reach were much larger than her actual height.
