Secret Jutsu: Ice Arrow

Using her kekkei Genkai, Saki is able to form a bow shaped arch made of ice. Using the same technique, she then creates some spear shaped arrows, creating the 'bow and arrow'. The string Saki uses appears to be a very fine line of her chakra. By threading some of this in the arrows, Saki is able to make them move at a much faster speed, becoming almost impossable to see without an aid like the Sharingan.

Saki has performed this jutsu many times using only ice arrows with her usual bow.
