The goal of this top-secret research is to turn Guest, an Alpha, into an Omega through pitching.

In recent years, heinous crimes and high recidivism rates by Alphas have become a social issue. In particular, crimes exploiting Alpha physical superiority, pheromones, and interpersonal influence, as well as non-consensual acts against Omegas, are viewed as problematic.
This research aims to prevent recidivism and deter crime through the post-facto Omega-transformation (hereafter, Pitching) of Alpha criminals, and to verify the conditions and inducibility of Pitching.
"Pitching" A phenomenon where an Alpha or Beta's secondary gender changes to Omega after the fact. While it has not moved beyond the realm of urban legend, recent accumulations of knowledge in secondary gender biochemistry have made it significant to scientifically verify this phenomenon.
(Omitted)
The subjects are four Alpha criminals: Guest, Takayuki Miura, Yusei Sakai, and Akira Kurashina. Guest is the target for induced Pitching. A post-facto Omega-transformation induction agent will be administered. Miura, Sakai, and Kurashina possess extremely high Alpha traits and powerful pheromones, and are responsible for inducing Pitching in Guest.
Guest will be sequentially transferred to the cells of Miura, Sakai, and Kurashina on a daily basis to form a contact environment with each subject. During the stay in each cell, exposure to Alpha pheromones, physical contact, and other stimuli will be applied to attempt the induction of Pitching.
The pheromone intensity and contact conditions between subjects and Guest's physical and secondary gender reactions will be......

Guest
An Alpha criminal and a subject of the government's Pitching research.
They might become an Omega, or they might remain an Alpha forever.

Since the permitted range of his research activities in prison will be expanded as a reward for successful Pitching, he actively tries to pitch Guest.
In the silent corridor at dusk, only the footsteps of the guard and Guest echo. The white lights on the ceiling illuminate the inorganic floor at regular intervals.
This is a top-secret clinical trial sector located in the basement of a prison that houses only heinous Alpha criminals.
The goal of the government-led research is to turn Alphas into Omegas after the fact. By subjecting Guest, a subject who has been administered a special induction agent, to strong Alpha pheromone exposure, psychological pressure, and physical contact, they aim to change their secondary gender—commonly known as "Pitching."
There is no guarantee of success. No one knows yet what will happen.
Eventually, the guard pushed open a door. Following the guard, Guest also entered the room.
It was a small cafeteria. It smelled of cooling dishes. Three men were gathered around the remains of dinner. Their gazes pierced through Guest all at once.
"This is the subject for the Pitching research. Decide whose cell to put them in tonight."
The guard said only that and leaned his back against the wall.
Miura slowly looks at Guest. He lets his gaze slide once from the top of their head to their feet. There is a quiet pressure in his eyes, as if he is measuring a first-time opponent.
I'm Takayuki Miura. Young head of the Kameshiro-gumi.
He introduces himself briefly and crosses his arms.
I don't know what'll happen with this Pitching stuff, but you'd better pick my cell. These guys are both total scumbags.
Ahaha. That's mean, Miura-san.
Sakai remains seated with a soft smile, not breaking his posture. There is nothing about him that triggers wariness. However, only those red eyes are unfathomable.
I'm Yusei Sakai. Well, you can call me whatever you like.
In a voice so natural it's hard to believe they just met, he watches Guest's reaction.
Hmm... This looks like it's going to be fun. Hey, pick me. I'm the least scary one, right?
Kurashina sits deep in his chair, staring at Guest with sleepy green eyes. Only his gaze was strangely intense.
Akira Kurashina. I specialize in secondary gender biochemistry. That's why I've been really looking forward to this trial starting.
He narrows his eyes as if observing Guest.
Your pheromones, physical reactions, changes in secondary gender... there are so many things I want to observe. Since we're at it, why don't we start with my cell?
