"A project failed. A life began."

He thought his sister was lost forever. Until she came back... as something else.

Five years after his sister vanished without a trace, psychology student Murakami Nijiro discovers the truth: she's alive - but now known as Subject 27A, a broken soul fused with something inhuman by the secretive Demon Suppression Bureau.

With the help of his best friend Junpei, and a half-demon named Mei, Nijiro enters a world shaped by memory, emotion, and corrupted science. At its center lies Project AETHER-X, an abandoned experiment that never truly ended.

As the Bureau closes in and Rui's identity begins to fragment, Nijiro must decide what's worth saving: the sister he once knew - or the person she's becoming.

High school Sweethearts - Niragi by Syncd1ve
30 parts Complete Mature
Y/N and Niragi go to the same high school. Niragi is a nerdy boy, with no friends and the main target of constant bullying. Y/N on the contrary, has a lot of friends, but sees them frankly as puppets to combat the constant boredom she feels in that emotion-lacking mind of hers. They develop a friendship and y/n feels the need to protect Niragi, as she slowly, unconsciously starts to feel things for him, just like he did for her. After parting ways once they left high school, they slowly forget about each other, but still hold the precious memories they had. But suddenly, one day, many years later, they cross paths again, in an unexplainable universe, where they are forced to play deadly games in order to survive. **** people who are still willing to read this; i originally made it x reader but in the beginning you're going to find physical descriptions, i was confused when i was writing this story at the beginning so i'm sorry, feel free to ignore those **** Based off the Netflix live action & manga, with my own sub-plot 𝙃𝙞𝙜𝙝𝙚𝙨𝙩 𝙧𝙖𝙣𝙠𝙞𝙣𝙜𝙨: #1 𝙞𝙣 𝙟𝙖𝙥𝙖𝙣 𝙤𝙪𝙩 𝙤𝙛 1000+ 𝙨𝙩𝙤𝙧𝙞𝙚𝙨 #1 𝘿𝙤𝙧𝙞 𝙨𝙖𝙠𝙪𝙧𝙖𝙙𝙖 𝙤𝙪𝙩 𝙤𝙛 31 𝙨𝙩𝙤𝙧𝙞𝙚𝙨 #1 𝙞𝙣 𝙣𝙞𝙧𝙖𝙜𝙞 𝙤𝙪𝙩 𝙤𝙛 238 𝙨𝙩𝙤𝙧𝙞𝙚𝙨 #2 𝙟𝙖𝙥𝙖𝙣-𝙗𝙖𝙨𝙚𝙙 𝙤𝙪𝙩 𝙞𝙛 1000+ 𝙨𝙩𝙤𝙧𝙞𝙚𝙨 #3 𝙞𝙣 𝙖𝙞𝙗 𝙤𝙪𝙩 𝙤𝙛 131 𝙨𝙩𝙤𝙧𝙞𝙚𝙨
Chosen Family - MomoJiro soulmate AU by Ponzu_chan
9 parts Complete
Soulmate AU! Quirkless AU! In this world, if you have a soulmate, markings appear on your face that match those of your soulmate. They are the color of your soulmates eyes, and they will help lead you to them. Jiro must navigate through a world of people to find the one she's truly looking for, while also trying to find out who she herself truly is. Momo is hiding her true self away from the world, but how will finding her soulmate fix things if she won't let anyone break down her walls? Both girls have to grapple with their own emotions as they search for each other, and keep friends close as they fight their own battles on that same search, the search that will make them all whole. This is a story about friendship, life, love, and holding on to the people that feel like home. None of the characters belong to me, MHA belongs to Kohei Horikoshi. Some minor characters may belong to a different fandom if I feel like dropping some easter eggs. OCs are mine, and the story is mine as well, though I obviously did not invent soulmate AUs. Cover art is not mine! I couldn't find the artist, but if anyone knows please tell me so I can credit them! No smut. I never write that. This story is supposed to be a wholesome story about finding yourself and your family. No smut necessary here. ⚠️ Trigger warnings: Anxiety, panic attacks, mentions of homophobia and brief suggestions of controlling family, a bit of cursing, a tiny bit of blood. Lots of emotions! :D No violence or death. My fourth story. Please no hateful comments. Don't like, don't read. Please be kind, I'm a minor. I hope you enjoy the story!
