Zero's staff

Zero's staff (ゼロのスタッフ) was a long thin rod/scepter that Zero primarily used as a weapon or way of communication over a vast distance. She sometimes uses it as a walking stick when feigning weakness to catch her victim off guard.

History
Zero's staff was first seen when she disguised her as Otsuyu. She didn't use it to fight, but did use it as a walking stick. Later, Zero used it to fend off the attacks of Moroha and Towa Higurashi. When Moroha, Towa, and Setsuna attacked Zero at the sight of Tōga's death, Zero used her staff to fight them until she was killed by Setsuna's Blood Blade and revived by Sesshōmaru. Zero used her staff to break the blade of Sesshōmaru's Tenseiga in anger. Kirinmaru arrives and infuriates Zero by separating the Rainbow Pearls, and Zero shoots s strand of web out of her staff to retreat.

Later, Zero takes her staff with her when traveling to see Nanahoshi. Like before, she uses her staff as a walking stick until she reveals her true identity. Zero then uses her staff to send the Rainbow Pearls to surround and trap Nanahoshi in a force field. After reabsorbing the Rainbow Pearls, Zero fought Towa with her full demomic power, channeled through her staff. Zero tried to goad Towa into fighting her, and when Setsuna arrived and calmed her twin sister down, Towa later refused to kill Zero.

Furious, Zero raised her staff above her head, and sent the pointed end towards her neck. Just before the staff could impale Zero's neck, Setsuna cut the that linked Zero to Tōga's spirit by her Yukari no Tachikiri. The staff stopped at Zero's neck and fell harmlessly to the ground. After Zero asked Riku to put her to rest and was fatally stabbed by him, she used her staff to show the half-demons twins why Kirinmaru hated half-demons. Zero also used the staff to telepathically communicate with Kirinmaru before dying. Her staff fell to the floor and restored the flowers around Nanahoshi's mansion.

Rion later picked up the staff and held it like Zero previously did as she and Riku journeyed to Mount Musubi.

Physical description
Zero's staff is grey and has a black spider emblem and details. The legs of the spider emblems form a diamond.
