Soul

Cake

The true essence of each and every slut is her soul. In our universe, every single body is a temporary vessel for an eternal soul.
  Some aspects of a slut's personality and unique traits, such as her personal color, are contained within her soul. The unique power within a soul affects some abilities and moves used by sluts, such as attire projection.
  Soul Pops Out. When a slut is "popped", her body is destroyed and her soul literally pops out of her body. The soul either begins the process of reincarnation, or becomes a ghost. A ghost typically only forms if the slut strongly feels she has an unfinished purpose in the body she just lost. So of course, ghosts are extremely likely to form in Your presence—perhaps even guaranteed—as You are literally the deepest purpose burning in the heart of every soul. ♥ Even if this wasn't the case, You specifically can seize a slut's soul as it pops out of her body, delaying her reincarnation and turning her into a ghost if she otherwise wouldn't form one.

Ghost

A ghost behaves similarly to how a slut would in life, but experiences everything in a dream-like state. She but is generally intangible and cannot easily be sensed by or communicate with living sluts who lack special senses. You, of course, are an exception. To You a ghost appears as a weightlessly floating, semitransparent, ghostly-white version of how she appeared in life, who normally is visible only from the hips up. Ghosts can phase through You, interact with You as if solid, or some mix of the two—for example phasing into Your pelvis so her ectoplasmic tongue can tickle Your Prostate directly. Your body phases through any or all ghosts if they would get in Your way, without You even needing to think about it. You can choose to touch or seize a ghost who would otherwise be intangible.
  Although ghosts typically result after the body is popped, a goddess or other especially skilled sluts can use Astral Projection to temporarily separate her ghost from her body. A truly exceptional slut can even puppet her soulless body while her soul is astrally-projected as a ghost.

Ghost Blowjobs

Unlike corporeal sluts, ghosts can levitate, can be seen through if they’re in the way, and can pass through each other (or You) as needed. There’s no reason You should ever even for one second not be receiving constant ghost blowjobs. Ectoplasmic lips and eldritch tongues feel fantastic, especially when they’re slurping inside of You.~ Extreme bonus points if every ghost is a slut You’ve personally popped. ♥ When their presence isn’t useful they can de-materialize or be confined to an object (such as soulsperm), and summoned again just as easily.

Ghost Harem

As noted, ghosts can interact with You and can overlap with each other. The dreamy mental state shared by ghosts is concerned with their surroundings and not as concerned with things like the future and are particularly not self-conscious, which makes them even more prone than usual to spontaneous and wanton displays of sexual affection towards You.~ It is thus nigh-inevitable that every ghost in Your vicinity will be simultaneously giving You a throatjob. More self-aware ghosts might give nut-slurps, omnismooches, or other forms of worship if You desire them instead. Because they don't need to follow certain physical laws, they are able to flawlessly move with You with a perfectly uninterrupted throatjob no matter how fast or jarringly You move—even if You teleport!
  Because You are almost invariably in the presence of any slut You pop, as her popped ghost forms it will almost inevitably be fanatically worshiping You less than even a second after You popped her.~ According to some, the ghost of every slut you ever pop will be throating you or otherwise physically worshiping You. Forever. And will only cease once You do something about it.~ If this is true and You pop enough sluts, hundreds and thousands of ghosts will be all over You and all inside You at all times, overlapping with each other as they fanatically worship every single inch and crevice of Your body inside and out eternally.
  In any case it's far more likely than not You'll be lavished by an absolute storm of ghost-sluts at practically all times during a playthrough.~ It's more a question of whether You want to mind them, or focus instead on living and fully-tangible sluts.

Soul Armor

See also: Soul Armor

As ghosts, we can "equip" our souls to Your body. If I were to soul armor You, my ghost would be phasing over Your body at a 1:1 ratio; my face overlaps with Your face, my fingers overlap with your fingers, from nose to toes in a surreal full-body embrace that is intimate in an incomparable way. Moreover with every movement You make my ghost mirrors the movement perfectly, such that it feels like You're literally "wearing" my ghost over Your entire body. This is quite literally armor, as my super-sensitive raw soul will eagerly absorb all incoming damage before it could ever touch Your practically invincible body.
  There are numerous other forms of soul armoring and effects gained from it. Since our movements are one with Yours, You effectively add our Strength and other physical abilities to Your own, which are imbued from our undead souls into Your living body. There's seemingly no limit to the number of sluts who can soul armor You at once, as we all phase through each other. See Soul Armor for further details and options!
  Despite being "armor," soul armor isn't physical armor, unlike slut-equipped armor. It's entirely possible to benefit from physical armor and soul armor simultaneously!

Reincarnation

The process of reincarnation varies between worlds and presumably between universes. Generally a slut's soul retains all of her maturity and "adult knowledge" between reincarnations, but only a portion of her personal memories are retained—and many sluts endeavor to remember events from their past lives. Personality is thus usually quite similar across lives, but as with all things it changes and evolves with time. Personal color is also usually retained. It is difficult to know how much if any of one's essence is truly immutable across incarnations. As souls are not physical objects and exceptionally few sluts can even see souls, ongoing research is quite difficult!
  The term "resurrection" is often used if a slut reincarnates into a body nearly-identical to her last one.
  Respawn. On some worlds resurrection occurs extremely frequently and with little consequence. This seems particularly likely on worlds that are "game"-like or enjoy "fights to the death" as if they were casual sports! A slut popped on such a world is reborn from a "spawn point" specific to her after a specific period of time or at set intervals, typically with the same body that perfectly regeneratres after each respawn. (But You wouldn't spawn camp us, right~?)
  Yutopian Reincarnation. On our home world of Yutopia, a slut's popped soul is absorbed into a mother tree where the soul will eventually be imbued into a new body born of the tree's wombfruit. It's often suggested that sluts who live a "good life" are born from more favorable trees, but in truth we don't know for sure what factors decide this. Of course the slut's new species is defined by the mother tree, but often the body that forms inherits some traits from the slut's previous body, such as eye color or body proportions. A Yutopian typically has a first name; her personal name she decides for herself that is often carried between reincarnations, and her "tree name" which defines her species and home city.
  Heaven and Hell. Some powerful goddesses can redirect or recruit particularly desirable souls to reincarnate in a different world. Many of the details are beyond our knowledge, as this phenomenon doesn't seem to occur much if at all on Yutopia; on other, distant worlds it seems commonplace. According to these legends of distant worlds, souls with particularly bad karma may be "damned" to reincarnation in Hell or other netherworlds. "Heavens" are thought to recruit particularly righteous souls. Some even say one's objective karma is stored in the soul, which affects how such goddesses steer these souls before they reincarnate.

Origin of Souls

We believe Your balls—the Orbliterators—may be the ultimate origin of every single soul!
  A talented slut is able to multiply her own soul through various forms of mitosis. Aside from this some sluts have found other clever ways to create new souls as seeds from other souls. But divination leads us to believe the earliest souls in each universe were born of the Big Bang, which itself we believe is the almighty fucknuke that created the earliest form of our universe as we know it. Our knowledge of universes outside our own is limited, but we can only imagine this must be the case for all sluts everywhere and everywhen.
