Z

Z, also known as Control-Z and Last Letter, is a Rare Skill.

This Rare Skill allows a Lily to rewind time in an area, at most, about the breadth of her armspan. As a Lily with Z can heal injuries that medical science is helpless to aid, this Rare Skill is the envy of medics and surgeons. It can also restore an overheated CHARM to working condition.

This ability to restore a CHARM allows the use of what is called the Impactor Style, a technique of fighting with B-type Armaments by forcing it back to ready state to attack again quickly.

Every Legion wants a Lily with Z among their number, but as it's just as uncommon as Phantasm, most of them have to go without.

Like Charisma, despite the rarity, the skiller value requirement for Z is actually low, at just 50.

No subskill version of Z is currently known to exist. But it is said Yamanashi Hibari can do "something similar to Z", fueling speculation that she awakened the sub-skill variant of it.
