Demonic Mirroring Ice Crystals

Using his kekkei genkai, Haku can create a dome of twenty-one mirrors made out of ice to trap an opponent. Twelve remain at ground level, eight are placed 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. 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 imbued with enough chakra to resist fire almost completely (Sasuke's Fire Release: Great Fireball Technique was barely able to make the rim frost melt).
