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

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.

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?

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.

A Femboy To Rember by Animestorywriting

Izuku Midoriya is a boy that has gone through hell and back. He was bullied for not having a quirk all through middle school by his "best friend" Katsuki Bakugo. Then out of the blue, he gained a quirk. His quirk is called "Emotional Damage". It isn't as bad as it sounds. It just means that when someone is faced with torture or something similar to it you will gain a quirk. It's pretty rare so he doesn't use it much. This quirk allows the owner to have a certain thing happen to him based on his emotions. Deku had gone through a Femboy phase so he just goes with it now, no matter what people say or think and somehow got a harem along the way. He has grown mentally and physically tough so it's hard to get to his heart. Will his harem the consist of his classmates be able to break down the layers to this badass femboy's heart or not. We will see~ ⚠️CONTAINS⚠️ mentions of suicide,cursing and Femboy/Badass Deku cause why not 😗💅 ꕥᵈⁱˢᶜᵒⁿᵗⁱⁿᵘᵉᵈꕥ P . S : Please if you do not like the very heavy usage of misspelling, cursing , talk of suicide , Femboy Deku please exit this story . I wish to remind all that this book was created when I was younger and so I did not have much knowledge on the topic of story writing . The layout of the book changes from a stage play to heavy paragraphs so beware of that. But please enjoy my other recent books made with better writing and less spelling errors.

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)

Unsung Hero: Corruption by LycanPerez

I grew up wanting to be a hero... A hero that could save everyone. A hero, smiling to reassure others, like All-Might! The greatest hero! This world took that away. This world is pain. This world is scary. This world is sorrow. This world is wrong... Is a villain allowed to protect what he loves? Because I'm tired of losing everything... Phoenix quirk, anti-hero/villain Izuku.

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.

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.
