The world is riddled with evil, stretching far and wide, into the hearts of many. But,
Pure evil... unadulterated, cataclysmic evil hides in the shadows, away from society's eyes, just waiting to peak their ugly heads from the darkness to strike. Strike without mercy and without restraint. It is up to the good, up to those willing to combat this mysterious evil to truly make a difference.

This is Book 1 of my Demon Slayer Deku trilogy. I do not own any of the My Hero Academia or Demon Slayer characters that may show up in this story. However, this story is my original work. Several OC's will have major roles within the story as well as minor MHA characters that didn't have much time to shine on the canon show. Cover art is AI generated.

Warning: If you are sensitive to domestic violence, child abuse, gruesome depictions of death, discrimination, bullying, depression, emotional instability, suicidal thoughts, cannibalism, murder & mass murder, etc. Then this is likely not the story for you, as these topics will be explored through the various characters throughout the book.(CC) Attribution-NoDerivs

Deku's descent into madness (MHA AU [oc insert]) by Djpon3cool

All of Izuku Midoriya's Life, he has wanted nothing more to become a hero just like his Idol, Allmight! Getting a Quirk from Allmight made it so he could get into U.A. and achieve this dream! So far he has made many friends, enemies, and is well on his way to be a hero! However when a suspect of many mysterious and unexplainable disappearances is interrogated by class 1A, Deku's faith in hero society fades as he discovers what happened to this female. So many questions, so little answers. In this story we see Izuku "Deku" Midoriya descend from a caring heroic fanboy, to a violent, villianous, mastermind that brings chaos to all of Japan. (Warning!: this story is NOT for the faint of heart, there will be many MANY disturbing scenes of gore, probably nsfw stuff idk yet, suicidal tendencies, mature language, and a lot more. So if you're here for 100% fluff, this ain't the fanfic for you) (This is an AU on Boku No Hero Academia by Kōhei Horikoshi, I only have rights to the plot, art, and my oc)

Who I am and Who you were - Villain!Izuku x Reader by Yell0wCa1

You have always admired heroes who made the world lighten up just because they were there but in order to shine there needed to be darkness. This darkness always seemed to be so far off, almost cornered by the light of the heroes. You soon had to learn that the darkness lurked closer than anticipated. And maybe, just maybe, the darkness was a lot more comfortable than the light. Disclaimer: Boku No Hero Academia and its characters don't belong to me.

The World is Yours - Cold-Hearted Demon (HIATUS) by FadedRonin

NOTE: This is the first story of my first-ever: Demon Deku trilogy, each story is different from the other, meaning Izuku's powers are different. EVERYBODY WANTS TO RULE THE WORLD. Izuku Midoriya lived a life of lies, betrayal, and deceit. As a child, he was diagnosed quirkless and got mistreated very quickly by his friends and family. Every day at school, he gets bullied by the other students and the teachers couldn't care less about him, since he was quirkless. Izuku gets beaten up every day by his friends and family, all because of one pathetic reason: quirkless. Izuku had enough of it, so, he took matters into his own hands.

Azrael (Vigilante Deku) by Chimera_Regarion

Izuku Midoriya had everything a 4-year-old child could wish for. He had a family, a home and a quirk that was like no other. Thanks to a tragic and very bloody night, he was left with nothing then his own memories of a happy past and his quirk to protect himself. He quickly found out that people are looking at him because of his quirk. All the people ever wanted was his quirk and not him. Years pass, and the little green bean learned to trust no one but himself. If one was to ask him what was his quirk, he would say he was quirkless. It was only a protection measurement he found out to be necessary. After all, a quirkless life was better than a life in a laboratory. One day he was fortunately enough to meet the number 1 hero and could finally ask him the question of his life. What will however happen if the symbol of peace gives him an answer he has never though he would hear? More importantly, what will he do once he finds out he still has family out there? Will Izuku be able to find them? And what will poor Izuku think about his new family? Will they be able to save him from himself? Let's find out! A/N: This is a mha fanstory and I have no idea where this is gonna go ... hope you enjoy! Please also feel free to correct my bad writing. Rights on the pictures go to the artist. I do not own mha, rights to the owner.

Satan Gravity [Discontinued] by LuluShinazugawa

New name: To Be A Hero (BNHA X KNY Male Reader) What happens when you put a kid who finds being a hero troublesome, but still somewhat finds himself enjoying it most of the time in the Hero course? Absolute chaos, I mean class 1-A was already a classroom filled with chaos. I mean they get attack by villains every 2.5 seconds, not to mention them plotting to kill villains. "What a fun class." Y/n smiled while holding a bloody knife. "This isn't what I sighed up for...." "I already have enough problems kids, but you just had to come along...." "Awww I love you too, Sensei!" ~ ~ ~ ~ ~ This is my second time doing a book like this and I hope I can live up to your expectations. This is a crossover between (just a little) KNY/DEMON SLAYER and MHA aka BNHA. This is also boyxboy because I suck at writing boyxgirl nor was I planning on writing one anytime soon. If you don't like it then don't read it. - - - - - Started: July 26 Ended: 10/10/21

A funeral... A Wedding... One Church by Chimera_Regarion

One jump, one adive, was it really the answer to the problem? Sure it was worth giving a try but would god really answer the prayers? Izuku Midoriya, couldn't stand it anymore. Each passing day he would get yelled at, beaten, burned and used as a personal punching bag. There was nothing he didn't experience. His heart was already beaten yellow, black and blue. He didn't know what it meant to be loved, to be cared to be just him! So in a desperate attempt, this young child went to a rooftop and did the only thing left to do and jumped.... only that as done with life as he was, life was not done giving up on him. A/N: This is a mha fanstory hope you enjoy! Please also feel free to correct my bad writing. Rights on the pictures go to the artist. I do not own mha, rights to the owner.
