>>6404184It's unclear. There's presumably either 12 or 13 Spheres, each of which embeds itself in a person and/or their mech. The Sphere starts out in a dormant state, and "grows" by feeding off the pilot.
Sphere of the Crying Maiden (Virgo): Reacts to intense sadness. Drains the user of the ability to see, hear, smell, touch, and taste, in order to isolate them further in their sadness. Embedded in the Gunnery Carver of Virgola Unit-1, which evolved into the Virgola Glory.
Sphere of the Wounded Lion (Leo): Reacts to physical pain. Traps the user in a smaller body which is more vulnerable to harm. Embedded in Mail, copilot of the Gunleon, and empowers it with the ability to transform into its Magna Mode. Unique in that it desired not to fight in the Holy War, and so hid in the repair-oriented Gunleon so that it would be able to avoid awakening.
Sphere of the Swaying Scales (Libra): Reaction to and effect on user unclear - seems to be hesitation or deliberation, like a scale being balanced. Embedded in the Brasta.
Sphere of the Lying Black Goat (Aries): Reacts to deceit - in order to keep itself fueled, the user is rendered unable to tell the truth once the Sphere awakens, like a ram charging in one direction. Embedded in Im, pilot of the Arietis - effect on machine unknown.
