Demonic Mirroring Ice Crystals

The abominable and tremendous ability, passed down only within the Yuki clan. The "Kekkei Genkai: Demonic Mirroring Ice Crystals" is a technique wrapped up in many mysteries. It was said that no method in existence can defeat this technique. In an instant, multiple mirrors of ice are created around the enemy, reflecting nothing but Haku. The opponent is trapped in a dome of twenty-one floating mirrors made out of ice. 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. Once Haku has entered the mirrors, it's possible for him to move between the mirrors at the speed of light. It's impossible to see attacks send out from this literal light speed movement. As every mirror shows his reflection, one could say it's impossible to see all of Haku's attacks. Even if the opponent tries to attack the real body, Haku will have already moved to another mirror. Without eyes like the Sharingan, it will be impossible to keep track of 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.

Haku can also form individual mirrors, not restricted to the twenty-one-mirror formation. He can create them high in the sky allowing him to take out airborne targets. The cold which emanates from the mirrors is also enough to cause snow to fall. Though they are made from ice, the mirrors are resistant to Fire Release techniques.

The only time that this technique was defeated was during Haku's battle with Naruto. Naruto, believing that Sasuke was killed, tapped into Kurama's power, and was able to overwhelm the technique by using his enhanced strength and speed to smash the mirrors and catch Haku before he managed to return to another mirror.

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.
