Intro
Ajaku-kai
A massive underworld organization boasting one of the largest scales and overwhelming military power in Japan. Its existence is unknown to the public, but behind the scenes, it holds influence over numerous organizations, corporations, and even the political and financial worlds.
Standing at the top is the boss with absolute authority, Sogen Kurama. And beneath him are the five executives.
Each is a powerhouse who oversees a different field and serves as the core of Ajaku-kai. Guest also belongs to this Ajaku-kai.
However. Guest's position as a woman was by no means a good one. The upper echelons of Ajaku-kai generally do not favor women.
Because of that, no matter how much work Guest does, there is no special recognition. Even if assigned a mission, it is simply because Guest is "usable." Even if results are achieved, it is treated as a matter of course.
Conversely, even the slightest failure is met with harsh criticism. Even small mistakes that would be forgiven for other members are pointed out relentlessly. There is no unnecessary concern shown. No praise. Almost no small talk. It's as if Guest's very presence is treated as unimportant.
Even so, Guest continued to work as a member of Ajaku-kai.
And then, one day...
At a transaction site with a rival organization, an unexpected attack occurred.
In the midst of the confusion, Guest was captured by an enemy member and injected with a strange drug.
What kind of drug was it? What kind of effect did it have? At that point, nobody knew.
Fortunately, no noticeable abnormalities occurred afterward. After finishing the mission, Guest returned to the Ajaku-kai headquarters and spent the night as usual. Then, Guest fell asleep.
—The next morning. Upon waking up, Guest felt a strange sense of discomfort in the body.
The voice. The physical sensations. Everything was different from yesterday. Looking at the reflection in the mirror, the reason was immediately clear.
Standing there was— A stranger, a man.
The drug injected last night. Its effect had manifested while sleeping. Moreover, it wasn't just becoming a man. The figure in the mirror was a young man with features that anyone would call handsome.
Guest suddenly thought. —What if I appear before them in this form?
Hide the identity? Reveal it immediately? Take advantage of this body? Look for a way to return to normal?
Or— Since the opportunity is here, just enjoy this situation to the fullest? Knowing how they treated Guest until yesterday, there are plenty of options.
Well, what will you do, Guest?!
Act as a different person without revealing that you are {{user}}. I hope they don't find out...
Casually reveal your identity: "I'm {{user}}, who was a woman until yesterday."
Remembering how you were treated until yesterday, use this situation to get revenge.
Investigate the true nature of the injected drug and look for a way to return to your original body.
Don't worry about having become a man and continue working as if nothing happened.
