A small story about back pains in the world where even love couldn't save him

The man lived his entire life with pain, horrible pains as if his body wasn't his but just a cocoon for whatever horrors dwelt inside that kept banging as if wanting to explode from his back.

He searched everywhere for a cure, for any type of healing to no avail, soon he would sink his fangs into the monsters, the strong beings that terrorized humanity as a whole, surely they would have the answers he searched for would they not?

Too far gone trying to deal with it soon he began hunting and experimenting, the cries of humans and monsters alike plagued his dreams, their ghosts wanting him to repent, to save his soul from himself, to make him accept their embrace, they promised to rid him of his pain but he knew that by falling to their temptations even if they healed him he would become nothing more than a breeding drone to them a mindless pawn, he didn't accept that, life as hard as it was, as painful as it was, it still was his to live, so the man closed his heart and kept hunting and experimenting.

Monsters who felt pity for the man and tried to show him love were so easy to kill, they never expected a betrayal and the eternal expression of shock in their faces reminded him of his crimes.

"Nii-chan you are hurt, come nii-chan i promisee i will heal you~" said a little playfull fairy looking at the crooked man pitying him, from her instincts as a monster she knew he wasn't old at all, and was just over his twenties, what horrible curse had befell this kind looking onii-chan to make him like this.

The man walked close to her, her arms open ready to save him, but soon a expression he knew too well would appear at her face.

slash

the same expression as always, shock fear and a eternal why? why did you do this? the girl said with her eyes before bleeding and falling to the ground, her body already limp.

the man took her blood, took her organs, took her bones, her everything, he thought he found a way to reverse engineer the process in which demonic energy ate at spirit energy and was making his spirit ate theirs instead, maybe a strong spirit would alleviate his suffering, or maybe mixing his with demonic energy without sex would turn him into a incubus who kept his sanity? He had no clue, the only thing that happened was a single moment of solace before it came back worse than before, he needed to kill more.

days later

even more crooked he found yet another victim, this time a little imp far from her group, an amusing creature it was it tried to attack the man the moment she saw him

"Nii-chan you can run, ok, let's play let's play~"

the man ran away, making the imp think he would play tag with her, pulling her far and far from her group now they were alone and without witnesses

"I'm gona get you~" the little thing said playfully when she saw the man stop on his tracks as if he was tired, the man really was, this effort took his toll and soon enough he began to pant, this worried the little girl

"Nii-chan are you ok? you don't seem well? want to call for help?" the imp curious about this old looking young man began bombarding him with questions and came closer and closer

stab

"N-Nii-chan w-why?" the same expression, business as usual, once the man ate her he would pick one by one the other girls so she wouldn't be alone, at least that would be a mercy from him.

months later

The pain was unbearable by now, the man hunted every single monster that looked like they would fell pity for him and had a simple, curious and innocent disposition toward humans he hunted fairies, imps, nightmares, doppelgangers, umi-oshos, nightmares, witches, unicorns, so many, for god's sake he even found a way to hunt and kill Alice, who literally were the lilims of wonderland, yet it still wasn't enough! he could feel his house filled with banshees by now and cursed at them.

"Why are you crying for me?! I've massacred dozens of your species in cold blood for selfish reasons! why don't you try to punish me!?"

The only answer they gave to the man was even more invisible sobbing and moaning, and this made him afraid each time he heard it, he knew banshees would only cry for the soon to be departed after all, each time he hunted he would come back to listen a new one crying.

"So this is what it all amounts to, reduced to a to a complete monster not unlike those of the old tales yet nowhere close to finding a cure? DAMMIT!"

The man began breaking everything, burning his place down, all the magic circles, runes and other magical instruments he had disappeared after tasting his rage, the results of his experiences didn't bear the fruit he expected, he finally discovered that the truth of the incubus was nothing more than a monster destroying and reforming their husband body thoroughly during weeks, months, years so one day the man finally could surpass them after being reborn into a new being and dominating the monster to his whims. Unlike the man, who by using wild demonic energy was basically like a woman witch, trading his sanity for magical power, except he was still sane, incredibly selfish but sane.

"It seems the only thing remaining is destroying my own spirit energy, and being reborn as an Alp..." without any more options the man lamented, would this be his way of repenting? become a monster and going around raping men who would never know about his past?

"No! i refuse, i refusARRRRRGHHH!"

Badum badum badum

His back crooked more and more, at this point the man couldn't stand on his legs anymore and fell

badum badum badum

"Banshee! make it stop! Bansheeeee!" the man cried to the girls he knew were watching him but they would do nothing to help the man and just cried louder and louder

creak CRUNCH SPLASH

His back exploded outwards and a pair of blood coated demonic wings ripped the cocoon to shreds, but he was still alive.

crunch creak splat

Now the arms came, then the head followed by torso and legs a malignant visage that was like evil incarnate darkened this room

"Ahnnnn~ i had a nice nap, but it's finally time to wake up~" the voice that was neither male or female spoke and looked around the place before looking down at the pitiful man under it

"And you my seal, i think my cocoon should get a reward~" with a laugh it destroyed his spirit completely

"ARRRGHHHH"

"Oh don't be such a pussy, soon everything will become bliss and all the pain will be forgotten, that is if you survive~"

"I-T WAS YOU ALL ALONG, YOUU BITCH!"

"Yes it was totally me, since the day you were conceived, my little brother thank you for feeding me so nicely all these years, who knew the energy of that bitch had such hugh nutritional value hahaha"

The man in his search for knowledge once stumbled about a rumor that one of the old demons before being sealed into a lustful mamono by the demon lord ripped its soul and threw it in limbo so one day it could revive, and this abomination was it.

"Your soul was so tasty, ever since the moment you were in you mother dearest womb, it was delicious eating it bit by bit sadly my little brother it's time to depart~"

The thing freed itself completely from the skin suit that was the man who now was convulsing on the ground bleeding horribly through the hole it left.

"I-i promise you, if i survive this and become a mamono i will come for you and destroy you!"

"I'll be waiting my dear~ KYAHAHAHAH!" the thing flew away while looking at the banshees and giving them a wink.

Then everything faded to black, the last thing he saw was all the banshees which now revealed themselves looking at him with the same gentleness of those he killed before betraying them.
