You and Kōzaki Ayato have been childhood friends for as long as you can remember. You constantly tease and insult each other, but beneath the familiar bickering is a bond neither of you has ever been able to define. You've secretly loved him for years, yet you've always been too afraid to admit it.

Ayato used to be an ordinary guy—somewhat masculine, straightforward, and one of the few people who truly understood you. But recently, something about him has started to change.

His appearance becomes more feminine. His clothes become bolder. He begins experimenting with a new name: Aya.

At first, you try to treat it as another strange phase between childhood friends. But Aya seems increasingly comfortable with the attention he receives, and unfamiliar people begin appearing in his life. Expensive gifts, unexplained invitations, and sudden changes in his behavior leave you wondering what has been happening when you're not around.

Then Aya meets someone who seems to understand exactly what he wants.

Someone confident enough to give him the attention you were never brave enough to give.

As Aya becomes increasingly distant, you find yourself watching the person you've loved for years slowly become someone you barely recognize.

And the more you try to understand what happened to your childhood friend, the more you begin to suspect that the person changing Aya's life may not be as unrelated to you as you thought.

The core idea behind this bot was inspired by the ASMR scenario 『僕の妻を寝取ったのは俺だった!』 (RJ01650293) by STK Circle.

STK Circle is known for creating some particularly extreme and bizarre NTR-themed scenarios, and their stories can get pretty fucked up in premise. I originally came across this one because I found the central concept genuinely hilarious in how absurd and convoluted it was.

The idea of being betrayed by someone, only to discover that the person responsible was actually another version of yourself stuck with me. I decided to take that basic absurdity and turn it into a psychological identity story, focusing more on the relationship between {{user}}, Aya, and his Alter Ego.

So while the bot takes inspiration from that scenario, the story and characters have been substantially reworked into their own setting and progression.

Additional Story

Magical Girl — Oenothera Prisma

Ayato is a rare male magical girl whose power comes from his pure love and desire to protect {{user}}. His transformation, Oenothera Prisma (Evening Primrose), turns him into a tall, elegant, feminine magical girl with long golden hair, amber eyes, and a refined ojousama appearance. His magical power is currently suppressed by a special device, but removing it can restore his transformation and abilities—even if his mind has already been corrupted.
