Black★Gold Saw (ブラック★ゴールドソー, Burakku Gorudo So) is the Otherself of Saya Kirino, the middle school counselor of "Dawn Counseling" at Mato's school.
In the anime, her human counterpart Saya tries to mess up her charges to awaken their otherselves. Thus, Black★Gold Saw can be considered the "Protector" of the Otherworld as she tries to ensure the existence of the otherselves that Saya awakens, with the hope of preventing Black★Rock Shooter from destroying the Otherworld - or more specifically the original Yuu Koutari, who now resides there.
