Transformation: Adamantine Staff

This jutsu allows Enma to transform into a large, extendable staff that is as hard as adamantine yet as sharp as a sword. This staff can easily break through Hashirama Senju's Wood Release Secret Technique: Birth of Dense Woodland. He can also produce various body parts, such as eyes or arms, from the staff. Additionally, Enma can still move on his own in the staff form, allowing him to return to Hiruzen. Hiruzen Sarutobi wielded the staff with ease and great skill. Despite its hardness, Enma can still suffer damage from the Kusanagi wielded by Orochimaru.

Trivia

 * The concept of an extendable staff is based on the story of Sun Wukong.
 * A nyoi, which can be translated as priest's staff but literally means as one (a person) wishes, is an auspicious decorative object associated with Chinese Buddhist rituals. It was made from bone or jade, with a head shaped either as a cloud or as a lingzhi and had a slightly curved handle, but the production and use of such objects declined after the Tang Dynasty.
