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. At some Gardens which are allied with or neutral towards GEHENA, such as Ambrosia and Kuramayama, Lilies who volunteer to be boosted are held in high esteem. However, it is common that Lilies are boosted without their consent.

Boosting appears to lead to a direct rise in a Lily's Skiller Value, as at some GEHENA-allied Gardens like Irma, it is a choice offered to girls who want to enroll but are not capable of being Lilies.

Side Effects
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. Lilies who have gone into lunacy can sometimes be temporarily returned to their right mind by being exhausted in battle or confronted by someone they felt strong affection for, but there is no indication that lunacy is permanently curable, and GEHENA is known to dispose of most Lilies who enter it.

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". Ando Tazusa has been mentioned as experiencing headaches, nausea, and paranoia due to having been boosted.

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
A few Boosted Lilies have been referred to as "Princesses of the Huge" (ヒュージの姫). The fundamental definition is that "the Princesses of the Huge are those who, despite being human, can compel the Huge to obey them," according to an unknown individual at Herensuge who was involved in the experiment that created Sasaki Ran. The term does not seem to be commonly known, even among Lily otaku; Futagawa Fumi mentioned at one point that she had never heard of them.

Some of the Princesses of the Huge also have unusual characteristics that are not considered to be Rare Skills or Boosted Skills. These include that they are often mistaken by the 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.

Several Princesses of the Huge are the result of experiments where unborn girls were boosted while still in their mothers' wombs, but according to Shiba Tomoshibi, it is possible to be made into a Princess of the Huge even following one's birth.

Known Princesses of the Huge are:
 * Kamigoori Marimo, and her 12 "sisters" created along with her at the Kuramayama GEHENA lab (most of who have been killed or gone missing.)
 * Kishimoto Lucia Raimu
 * Luise Ingels (who has not been referred to as a Princess of the Huge, but was boosted prenatally like Raimu and Ran were.)
 * Sasaki Ran
 * Shiba Tomoshibi
 * Possibly Gozen, who has demonstrated similar powers.
