Summary
He watches as Saika Takao roams inside the Metaverse, stealing treasures alongside the other Phantom Thieves.
She was gifted with the power of demon summoning, yet she had no Persona of her own.
She had no will of rebellion, that's why she's the perfect pawn.
One day, law and chaos will come to clash.
Under his guidance, Saika will have no choice but to bathe in the blood of her friends and recreate the world through the Conception.
A world free of all crimes, just like what he intended.Or,
What if SMT demons replaced Persona shadows? What if more mythological figures participated in the 'game'? What if a law-aligned OC joined the Phantom Thieves? What if there are various SMT elements and characters in P5R? Basically, a bunch of 'what if' inside a single fic.
It could be read fandom blind (or at least, you can read it without the context of one fandom)

Summary
“They sleep with a light on. Never in pitch black darkness, like they should as adults. They keep a source of light, always. A small night light, one of those made for little children, that sit on their drawer and bathe the room in a faint, soft green glow.
It doesn’t keep the nightmares away, but it makes them a little more comfortable - As much as recurrent nightmares can be. At least, when one of them wakes up screaming in terror, they’re not lost in an endless abyss and the silhouette of their bedroom – drawer, closet, mirror, tv, the landscape painting hanging on the wall - drawing itself in the low-light grounds them in reality a bit faster.”Even after Naoki restored the world the way it was, their time in the Vortex still hovers above their minds like heavy thunderclouds.

Summary
Naoki wondered why everyone assumed he was a demon when he still looked like a human. The only big difference he could see were the weird tattoos... Was it the pattern? He half turned in front of the hospital’s bathroom mirror trying to get a better look at his back and the...horn? Spinal growth? He tapped it with his finger, it felt like some kind of stone. Were all his bones like that now?
“Didn't take you for someone who liked to admire themselves,” Pixie chirped getting kinda bored waiting for him to finish.
He glanced at her, mumbling “I look human...”
Scenes that illustrate some of the conflict and confusion a new half demon might experience, meaning that Pixie has a big role as the one who explains a lot of demon stuff to the demi-fiend.
A lot of this is me projecting my own morality and thoughts about the Nocturne world, but with a nice helping of Pixie being a good partner through the vortex world. It'll probably touch on every major event and/or character in the game. -

Summary
"It's not crazy to want to kill everyone responsible for the state of the world, Niijima. It's crazy when you don't."
On April 22, 2016, a high school coach leaps off the top of a building, after confessing to the physical and sexual abuse of multiple students under his watch. Makoto Niijima is sent out to investigate the circumstances behind his sudden suicide attempt, only to come face-to-face with a bespectacled black-haired delinquent transfer student with the hateful eyes of a corpse.
From there she becomes embroiled in a nationwide conspiracy involving an alternate reality born of the collective unconscious. If she is to survive this world where only demons and fiends thrive, she must unlearn everything she has learned about justice and truth. For when only one's strength can make a difference, justice is a lie and truth is meaningless.
Will she make it through? And if so, what will be left of her?
[Horror AU novelization of Persona 5, from Makoto's POV, with SMTIII elements | Can be read with no knowledge of Morning Star or SMTIII: Nocturne]
