The Dance of the Shikigami is a technique used by Konan, which combines her talent for origami with ninjutsu.
By converting her chakra into paper, she can transform her entire body and clothing into numerous sheets of paper. She can then control and shape the paper into various things, such as spears for attack, butterflies for spying, and clones for supplementary purposes. She can create paper wings on her back to fly (though she can hover without them) and use them to fire paper in rapid succession. She can also wrap her target in paper, restricting their movements and asphyxiating them.
In this form, she is weak to oil-based techniques, which causes her paper to stick. However, she does not hold the same weakness to water. She is somewhat resistant to fire, as seen when Jiraiya's Fire Release: Flame Bullet barely damaged her. Her paper seems to be expendable, including paper converted from parts of her body.
Shikigami, when written as 式神, refers to a kind of spirit summoned to serve an onmyōji, a kind of sorcerer. These spirits are often depicted as changing into small pieces of paper once harmed or finished with their task. In the name of this technique, the kanji for "god" (神, kami) has been replaced with the kanji for "paper" (紙, kami), which is pronounced the same. This is likely done to emphasise the paper nature of Konan's shikigami and to point out the subtle difference between them and traditional shikigami.
Her ability to make wings out of paper mirrors her title as "God's Angel" in Amegakure.
