Boosted Lily

Boosted Lilies (ブーステッドリリィ), also known as Enhanced Lilies (強化リリィ), are Lilies that have had Huge cells implanted into their bodies by GEHENA, granting them special Boosted Skills that Lilies do not naturally have, as well as enhancing their Magi capacity and causing it to deteriorate more slowly. The various branches of GEHENA may do this to make the Lily stronger, purely as an experiment, or to save her life if she is mortally wounded.

The boosting process has severe side effects. Lilies who are boosted to an excessive degree, or who were unable to mentally endure the strain of it, can be driven into a state called "lunacy" in which they attack other life forms indiscriminately, similar to how the Huge do. Additionally, the bodies of some Lilies may reject the Huge cells, which places their lives at risk. Should this occur, the boosting process can be reversed or partially reversed to stabilize the Lily, but only during a short period after it is performed.

Even outside these extreme consequences, the physical and mental side effects are unpleasant enough that many Lilies profoundly regret having been boosted. One example is Takamatsu Shiera, chairwoman of Yurigaoka and a Boosted Lily herself, who made it Yurigaoka's policy to oppose GEHENA because of her wish that "no one should have to go through what I did".

Resurrection
It is possible to boost Lilies who are already dead and to resurrect them by doing this. This normally drives them into an immediate state of lunacy, with only one known exception.

Princesses of the Huge
GEHENA has experimented with boosting unborn girls still in their mothers' wombs. These girls, when they become Lilies, have characteristics that other Boosted Lilies do not: they are mistaken by most Huge as fellow Huge and are never attacked by them, can sense the presence of nearby Huge, and have a strange reaction to being near other Boosted Lilies of their type that mutually increases their power. Lilies boosted prior to their birth are referred to as "Princesses of the Huge" (ヒュージの姫).

The two known Princesses of the Huge are Kishimoto Lucia Raimu and Sasaki Ran.
