Since Kireina's soul became Rank 5 and her soul mutated, she gained the power to control the residual souls that she had eaten.
In Genesis, the composition of the Soul is even more complex than on Earth, where it is only a single ethereal existence.
Thanks to the Soul Attribute, souls have different compositions, this is thanks to both Magic Energy and Life Energy, which after being absorbed by a Soul through their physical bodies, can create Soul Energy.
Soul Energy can be naturally generated by a Soul as their bodies keep living, and souls can naturally raise in their ranks as their physical bodies live for very long, but there are other methods to raise one's Soul Rank, that is by eating other Souls or nourishing one soul with different Psyche Nourishment Techniques.
However, most of these techniques require Aura, which also requires an advanced rank in Soul, so usually, the quickest way is by eating Souls. By consuming souls with one's soul, the Soul Energy will be instantly assimilated, while the residual soul will become part of one's soul, the memories may or may not transfer to the user's soul, but they usually just dissipate and become part of the soul that ate them.
This Residual Soul is a part of the soul that contains the being's mind, experiences, feelings, and a small quantity of low-quality Soul Energy. Through their experiences gained in their lives, if a soul is reincarnated with its memories from past lives, it will usually carry over skills as well, through Genesis's Skill and Classes System.
A Residual Soul can be torn apart as Kireina did previously, and whenever she eats the parts, the Residual Soul will naturally rearrange, but in a bizarre and grotesque form, all of its memories that made it one "Self" were torn into pieces and combined again, it will, of course, be greatly affected.
After obtaining the Skill [Inner Realm; Soul World], and leveling it up, Kireina had been slowly learning how to move these Residual Souls, and thanks to her Sin of Lust, an entity created by the System to represent a special power given to certain Epic Users, she can reincarnate Souls, albeit randomly, the Sin of Lust will mostly obey her, but it cannot discern her intentions.
Existences capable of reincarnating souls are very few. It's different than manipulating souls or eating them, reincarnation requires a whole different procedure, and it's usually related to the Divinity of Gods.
Only the most masterful of Necromancers were able to put souls into physical bodies, but they were usually Undead, so it would not count as real and true reincarnation into a living body.
And not every god was capable of such thing, but only the ones belonging to the Supreme Goddess of Souls and Reincarnation Pantheon, gods whose divinity is naturally of the Soul Attribute, but these existences are rare by itself, and most of the gods are just the Supreme Goddess descendants who inherited part of her powers.
The Supreme Goddess of Souls and Reincarnation oversees the reincarnation of all types of souls and manipulates them to maintain order. Usually, souls would be called to her Divine Realm after they drift around the Realm they died.
There is only one exception, being the Great Goddess of Death, Hel, and her pantheon… Hel does not have anything to do with the Supreme Goddess of Souls and Reincarnation but often interferes with her, taking souls to her Realm of Helheim, which she usually uses to raise her Undead or just play with them or collect them like toys. She often collects Souls that were blessed by Gods as her hobby.
The Supreme Goddess has tried to make her stop, but other Supreme Gods stopped her before things could go into a fight as if Hel were to die, her divinity related to Death would disappear, and dying would become something impossible for mortals unless they were completely erased from existence.
This is because the True Spirit that once ruled over Death was destroyed into pieces and the pieces were assimilated by Hel, obtaining its divinity, which she uses as an advantage to have a high position as an essential entity even amongst Supreme Gods.
Thanks to the System and the Gods petitions and their dungeons, the Supreme Goddess had managed to create inner reincarnation cycles inside dungeons, keeping the souls of the monsters constantly recycled, usually with their memories erased, however strong monsters such as bosses would remain with a part of their memories with each reincarnation.
And through the System created by the World's Will and the System Master help, she can reincarnate "Strong Individuals" into Summoning Spirits, Familiars, Dungeon Gacha Monsters, and more.
Such "Strong Individuals" are usually chosen by the System Master himself.
The Summon of Familiars and Spirits was not possible in the past, before the System, neither the summoning of the Gacha System in Dungeons.
These systems were solely created by the System Master, who took some suggestions from other worlds such as Earth for inspiration.
He saw that humans loved to summon historical figures, heroes, spirits, and monsters as their aides, and because the World's Will told the System Master that he needed to do anything he could come out to strengthen mortals, he came with the idea of giving selected individuals Summoning Skills.
However, Summoning Skills are often rare and are not given willingly to anyone. They would be usually connected with Destinies, Epic Skills, God Blessings, Artifacts in Dungeons, and so on.
Through History, Humans capable of summoning Spirits and Familiars are exceptional individuals, often seen as heralds of the gods. Thanks to the strength of their summoned spirits, they can fight and overcome obstacles. Summoning Spirits and Familiars are reincarnated individuals who were once powerful warriors who had naturally high strength, magic power, or intelligence.
Although they would be reincarnated in a weakened state, Summoned Spirits and Familiars are capable of quickly raising in strength as they recover their past life strength while remaining completely loyal to their summoners.
Due to this, there is a misconception, as it is believed that summoned Spirits are related with True Spirits, but this is false, Summoned Spirits are Artificial Spirits made with the souls of former mortals. They are usually referred to as Demi-Spirits by the Reincarnation Pantheon Gods and some humans.
And now, as the Supreme Goddess pondered this information, she began to analyze what has been recently happening in the Realm of Vida, where a certain individual has been draining the souls of her system to create summons crazily.
A being capable of using Summoning Skills multiple times, but not from soulless monsters, but Familiars that are given souls, and even Spirits, Dryads, and Gnomes.
And now this individual was not only still doing this very annoying thing for the Goddess but was also reincarnating Souls on its own, without even asking her permission.
Due to this, her Reincarnation System was going crazy, calculating the number of souls reincarnated while also canceling the reincarnation of certain souls.
To think that there is such a being that can annoy a Supreme God, it is almost something ridiculous to say or even think.
But her feelings were genuine, the Goddess was certainly, very annoyed. A feeling that hasn't run through her mind for thousands of years, the only time she could recall being annoyed was when the other Supreme Gods, in their stupidity and hunger for power, ended up destroying Genesis, their only home, which ended in the creation of the countless Realms that they now govern.
"Sigh… What should I do?" she sighed.
The Goddess of Reincarnation had the appearance of a young woman in her twenties, with long golden hair, so long that it resembled a sea made from liquid gold. Her irises were pale yellow, and her skin was pinkish white.
She had a large crown made from flowers of all colors over the top of her head, she was currently wearing a very normal-looking white dress and nothing else. Her Aura itself radiated an incredibly thick amount of Divine Energy as if her whole existence was just this power.
Unlike some of the other Ancient Gods who raised from mortals, the Goddess of Souls and Reincarnation was not someone constantly pursuing power and cunningly plotting against others.
She raised from a humble place hundreds of thousands of years ago and was instructed by a True Spirit that managed the Reincarnation System, when the War between gods broke out, this True Spirit was killed and she was given the task to manage the System by the World's Will.
Due to this, she grew rather simpleminded and a little bit lazy. She saw Kireina as an annoyance, but she wasn't as concerned.
"Well… it's just a mortal, it has to die someday, right? And whenever it dies, the problems will erase as well"
For gods, the entire life of a mortal was like some days, they had lived for so long and were tireless, so the perception of time for them was rather different.
Even if this mortal were to live a thousand years, it was nothing for her, so she just decided to leave these problems to resolve themselves… while leaving her children to assess the situation in the meantime.
The Supreme Goddess then lazily sat down in her large bed made out of countless flowers, opened a space in her Divine Realm and grabbed a strange and colorful plastic bag, opened it, and began to snack in some of Earth's Potato Chips, while drinking some Cola.
"Haah… Nothing is better than lazing around while eating snacks"
Some years ago, the Supreme God of Space and Creation alongside the System Master began to ask for her help and cooperation over reincarnating individuals from different worlds.
At first, the Goddess didn't like the idea as it would be too troublesome, but after getting convinced by the delicious food of worlds such as Earth, she happily obliged.
While other gods like Agatheina, the Goddess of Blood, only think about raising in power and owning the world, the Supreme Goddess of Reincarnation, who was at the peak of everything, was lazing around while eating junk food…
But junk food wasn't the only thing that came from Earth…
The Goddess opened another space in her Divine Realm, taking out a large TV, videogames, and several gaming consoles… And started to play her favorite game, Grim Souls.
"Alright, I'm going to beat it now, I've been leaving this game aside for hundreds of years after I lost and got a little bit angry… But now I have become a new woman, I know I can win!"
Yes, that is correct, this is the Supreme Goddess of Souls and Reincarnation, the one worshiped by millions of living beings across all Realms…
"WHAT?! I DIED!"
Meanwhile, Agatheina, the Goddess of Blood, grimaced what had just happened to her.
She was currently resting in her large bed while being attended by her descendants, who were feeding her with their blood.
"T-To think… that a mortal could damage me…! An Immortal Goddess!"
Agatheina glanced at her currently nude body, a large scar was present in the middle of her rosy breasts. It had already cicatrized, but it would not disappear no matter how much Divine Energy she poured into her Regeneration Abilities.
For a God who possessed limitless Vitality and Immortality, this was ridiculous, even more, when it was made by a mortal.
The powers of Kireina's Chaos-Attribute Magic coupled with the effects of Divinity Devour and her Aura and Soul managed to do an impressive amount of damage to the Goddess.
However, there was something in the effects of her attack that Kireina did not realize. By using coating Divine Devour into the Chaos Attribute Sphere, the Sphere initially only devoured the Divine Energy sent by Agatheina to the Vampires, but instead of just being eaten and erased, this Divine Energy was reused to attack back at Agatheina by using the small connection she had between the arc of crimson light that she sent.
It seemingly worked not only as a way to erase the Divine Energy but as a counter-attack, throwing back the energy at her but enhanced by the Chaos Attribute, which she was not able to suppress, ending in the scar she had in the middle of her chest.
"Just what kind of Skills does this mortal possess?! The ability to eat Divine Energy and then throw it back to me… And her attack wasn't of an Attribute I've seen in thousands of years… Chaos Attribute… To think that a user has been finally born!" She shouted, "Not even Gods have mastered this Attribute… There isn't a single God with Chaos Divinity, there may be a Supreme God of Law, but not of Chaos! T-This completely changes everything… S-Should I "curry flavor" this irregular? B-But how could a goddess do such a thing! I-I…"
As Agatheina struggled with her thoughts, which were between allying with Kireina or not, Kireina was currently waking up from her sleep inside of the Cilane Kingdom royal Castle, where she found some of her wives who had gone through slight changes.
"They evolved…"
