Summary
Ayato Aishi was just like his mother at times. Always emotionless, and always so cold. It was almost as if he was his mother, except for one deadly detail.
He didn't have his Senpai.
He hasn't found his spark, his one true happiness. And he doesn't know if he ever will. But one day, many things changed.
10 men over the course of a full school year. Will he manage to find his love of his life, and get away from these obstacles that people call his harem?
He isn't really sure yet.

Summary
Ayano Aishi, a seemingly ordinary student, hides behind a mask, so much so that nobody could guess that she was the perpetrator behind the escalating murders at the renowned Akademi High School. Ayano begins to cultivate "friendships" with various boys in her school. These relationships, however, are a far cry to being genuine. For Ayano, they are means to an end; a way to blend in, and gain information. Or so she thinks.
Alternatively;
Ayano learns the power of friendship.(this takes place in the mission mode universe!!)

Summary
Osano is a hot-headed metal guitarist estranged from his prestigious medical family, scraping by with odd jobs. Ayano Aishi is an emotionless honor student with a taste for pastel aesthetics and an after-school job no one would suspect—she’s a contract killer. The irony? Osano is a crime scene cleaner… unknowingly erasing Ayano’s work.
Both work under the same shadowy figure—Chishiki Ito, also known as Info-Kun, a reclusive information broker with ties to the Yakuza—receiving cryptic instructions that keep them narrowly missing each other in the city’s underbelly. Their college life is no safer: Megumi Saikou, their calculating classmate and son of Akatsuka City’s most powerful family, is always watching for weaknesses. Meanwhile, Osano’s rowdy circle of friends, Ayano’s quiet evasions, and the government’s mounting investigation into Chishiki push the two closer to exposure.
As near-misses turn into dangerous overlaps, the boundaries between their personal and secret lives begin to erode. The city’s power struggles tighten around them, old grudges and new alliances emerge, and each step closer to the truth risks shattering not only their work… but their fragile, growing bond.

Red Strings Reversed [A Yan Sim Swap AU] by katoxeem

Summary
[NOTE: I absolutely DO NOT support Alex nor condone any of his actions. Hes a terrible person and has been for a long time, people have only caught wind on it recently. I'm simply making a rewrite of the game's storyline. I loved watching Kubz Scouts play it, and I've been seeing people redesigning the rivals, which inspired me to create an AU with my own spin on things.]
Ayano Aishi doesn't understand love.
Actually, she doesn't quite grasp any emotion for that matter. But she watches. She notes how others preform -quick giggles, gifts, flushed expressions, the gestures. And she attempts to mold herself to those standards.
So when she meets 10 boys, including a disturbingly sweet upperclassmen, she suddenly finds herself the very center subject of this foreign thing; love. Or at least, what she assumed is love. She studies their every move in hopes of understanding emotions better.
Ten Boys.
Ten Weeks.
All head over heels for her in their own way.
Especially Taro Yamada.To her, it is all simply a game she does not bother to comprehend nor win.
Until the bodies began to pile.
All characters and game belong to Yan Dev

The Devil works hard but Ayano Aishi works harder (to prevent a murder) by AbielaAbitalEscarraGlimnt1

Summary
“Ayano, you have to look after your brother. Since you’re the older sister and you know better, you have to make sure that Ayato doesn’t get into any trouble. Okay sweetie?”
Because of Ayato’s extremely high percentage of the Aishi curse, he couldn’t feel any sort of emotions.
So that meant that he couldn’t form his own actual opinions on anything because he felt nothing.
That usually left Ayano as the one to make decisions for the both of them on stuff that should have been easy to decide, for normal people that is.
(But Ayano and Ayato aren’t normal)

Summary
I've gotten back into YanSim since playing it for the first time in years. Anyways. I find very few good fanfictions for Taro x Ayano, since most seem to be geared towards Budo. I decided to write one. This idea is actually owed to another author on this site, who defo wrote it better than I did and is therefore owed most of the credit. (She is AmaAishi)She stopped updating in 2022, so I was forced to take matters into my own hands. I hope she isn't mad at me :'( Here it is.
Taro Yamada has a... condition. He feels all of the emotions of his peers. All of the time. Constantly, the hallways are full of drowning feelings that leave him feeling like a beached whale. Until... he finds someone who takes away that burden, cancelling out his disease and leaving him feeling strangely calm. He needs her. He needs to have her. Does she feel the same?

Summary
Ayato Aishi is an anomaly. A male heir of his family's generational curse that only has ever affected female born firstborns. It makes some semblance of sense; he is a firstborn and only child after all. His mother enrolled him at the same school she found her soulmate at in hopes he'd find the same cure, but, now in his third year, he has yet to stumble upon his fix.
