Assuming the form of a young woman named Zu (ズー, Zū), her true form is the Bee Woman (ハチ女, Hachi Onna), armed with the ability to fly with the wings on her head and shoot needles from her hands. She was the one who kidnapped Kana for the sacrifice. Upon news of Agito's death, Zu was sent to avenge her brother. She used her crimson ribbons to trap Kouji and drop him from the skies after shedding her human form. But he assumed Rider form and overpowered her on his bike and on foot.She shot Kamen Rider J in the arm with one of her needle attacks, grabbing him and taking him into the air. She was mortally wounded upon collision with the Fog Mother's ship, seeing Garai one final time before she died and faded into the mist.
