Soul
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.
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.

Reincarnation
The process of reincarnation varies between worlds and presumably between universes. Generally a slut 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.
The slut's essence, the core of her personality, is always retained in the soul itself. We are still researching how much is truly core and how much can change from one life to the next; nature versus nurture, as it were. Some theories suggest the core itself can change at least slightly with each new reincarnation. For example a slut's personal color is almost always retained between lives, but even this is not concrete. Perhaps a Ship of Theseus situation? As souls are not physical objects and exceptionally few sluts can even see souls, ongoing research is quite difficult!
Respawn. On some worlds reincarnation 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.
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.
