Phantom Mirage

Miria (the Organization's former No. 6) is the creator of this technique. The technique allows the user to briefly move at a frightening speed, thereby leaving after-images to confuse opponents, thus earning her the title "Phantom Miria."

Usage
The technique entails a split-second burst of yoki enhances the user's speed to the point that the user leaves an after-image. It confuses adversaries and is used primarily to dodge attacks or occasionally launch an attack.

Before the seven-year timeskip, the Phantom Mirage is limited to about 20-30 safe uses in a fight, due to intense strain on both the mind and body.

After the Northern Campaign, the Seven Ghosts are forced into completely suppressing their yoki auras. As such, Miria developed a "New Mirage" that relies on base agility. This New Mirage, though slightly slower than the original, allows for more precise movements and, most importantly, near-limitless use.

When combating Hysteria, Miria unveiled a new varient of the technique. Instead of bringing her yoki to her limits in a burst like the original Phantom, she would actually far surpass her limits in a Momentary Awakening, dispensing with precision entirely in favor of raw speed and violence. The technique carries great risks, putting even Miria's humanity on the line in exchange for speed that surpasses both the standard Phantom Mirage and the Elegant Technique.

Phantom Mirage and the Elegant Technique
The Elegant Technique is a technique developed by Hysteria the Elegant, one of the three warriors resurrected by Dae. Like the Phantom Mirage, it also utilizes a brief burst of yoki to allow for an immense boost in agility. The difference between the two techniques lies in the very nature of their usage—Miria uses her technique to get some distance from her opponent but Hysteria uses hers offensively. Miria also states that though the speed of both techniques are roughly the same, the precision of Hysteria's movements are on an entirely different level.
