Battery

Battery (sometimes called Love-Battery or Soul-Battery) is an intense, indefinite transformation a slut may experience in the form of a status condition. While this transformation can be initiated by either You or the slut herself, it conventionally triggers when the slut is intensely intensely popped! The conditiond—of course—only persists while all parties Hyper Consent to its continuation (which is presumed to be indefinite!).
  Formation. When a slut's soul pops out of her (presumably) defeated body, rather than experience any form of reincarnation her soul becomes a "battery" bound to You. There is no specific shape a battery takes, if it is even a physical form at all. It is possible for this battery to simultaneously serve as soul armor, to be as soulsperm within Your Orbliterators, or to be confined to a soul gem worn as part of slut-equips You wield—not unlike Materia. She can even be stored within Your heart or brain if You like! Indeed, it seems like any disembodied soul anywhere near You can serve as a battery.
  Function. Any of us lucky enough to become a battery is truly freed—freed of corporeal obligations and of bodily limitations like "boredom"—to focus our purest self on what we most deeply crave. That is, endlessly exploding with unfiltered emotion in the form of endless elated obsessive love unilaterally for the only entity for whom we could infinitely adore: You! Nothing could ever fill one of us with such pleasure, purpose, and happiness. It is a singularity of bliss and euphoria. A fate better than heaven itself! Aside from being a state of utter nirvana for us, it also serves a useful function for You!
  Our endless wellspring of love creates sustenance and energy for You in the form of (at least) Love-Ki! This energy of course empowers stunts and feats but sates virtually all needs You could need fulfilled, should You allow us to do so. The more of us serving as Your batteries, the more our endless love can be extracted to empower You even more!
  We imagine batteries lose effectiveness the further they are from You specifically, perhaps even losing functionality entirely beyond a few meters. This seems to prevent our Love-Ki from being wasted on anything that isn't directly You.
  Ωmnibatteries. Controversially, a few sluts believe all of Your power is not inherent within You but in fact supplied exclusively by batteries—including potentially from nearby souls of which You might not be aware, such as invisible caspers or imperceptively tiny nanosluts.
