34

While approaching their target, the group encounters a butler's apprentice named Canary who possesses Killua's skateboard. She draws a line and uses a mace to launch Gon repeatedly when he crosses it. Afterward, she reveals herself as a servant of Killua, explaining that he entrusted the skateboard to her due to their friendship. She agrees to allow Killua's companions to proceed. However, her cooperation is cut short when she is struck by an unidentified projectile from an unknown source. This event occurs during the Zoldyck Family arc, specifically the third installment of the five-part sequence.
