Demonic Mirroring Ice Crystals

Using his kekkei genkai, Haku can create a dome of twenty-one floating mirrors made out of ice to trap an opponent. Twelve remain at ground level, eight float above the first twelve and angled toward the ground, and the final mirror is above the rest and facing the ground. Haku can then enter one of the mirrors and instantly transport to another mirror. While moving about he bombards the opponent with attacks at very high speeds, such that the rest of the world appear to be moving in slow motion compared to him. Also, all the mirrors show a reflection of Haku, so it is difficult for the opponent to discern which mirror he is in.

If the mirror Haku is in is broken, he can leap out of one of the fragments and continue his attack or move to another mirror. The technique requires a large amount of chakra to maintain, so Haku's movement becomes progressively slower the longer he maintains the mirrors.

Though they are made from ice, the mirrors are resistant to at least low level fire techniques (Sasuke's Fire Release: Great Fireball Technique was barely able to make the rim frost melt). The cold which emanates from the mirrors is enough to cause snow to fall.

Haku has also often been seen forming individual mirrors, not restricted to the twenty-one-mirror formation. Haku has also shown the ability to attack people far in the sky with his Ice Mirrors, as shown when he attacked Sai's team when they were flying in their bird drawing constructs.

Trivia

 * In the manga and anime, Haku calls this technique by its full name, . The databook entry for this technique drops the "Secret Technique" part.
