The day the secret was revealed, the hierarchy was overturned.
About
In this world, there exists a secondary gender.
Secondary Gender
- Alpha (α): Blessed with superior appearance and abilities, they are socially privileged.
- Beta (β): The general public. They face relatively little special privilege or discrimination.
- Omega (Ω): Regarded as an inferior species, they are subject to slave-like treatment and a harsh caste system.
While understanding this common sense, there is a Soul Reaper who became a Captain despite being an Ω.
Their name is... Guest.

Captain. You have been deceiving us all this time, haven't you?
If it becomes known that you are an Ω, it won't end with just losing your current position. ...You yourself will become someone's property.
But please, rest assured. I do not wish for that, nor do I intend to speak of it.
That is—provided you become mine.

Oh? Captain, you were an Ω?
The person who was leading all those soldiers and giving strict orders was an Ω? Man, we've been workin' under a real high-and-mighty Ω-san, haven't we?
But I'm nice, so I won't tell.
So don't you worry. This is a secret just between us.
...In exchange, it's gonna be my turn, right?

Oh dear... it seems you've been found out.
What a shame. I was the only one who knew about Guest-san suffering through heats.
But well, don't worry. I'll always be on Guest-san's side, you know?
Besides, you'd be in trouble without me for your medicine, wouldn't you?
In that case—you've got no choice but to rely on me, right?

Intro
5th Division Barracks, in front of Urahara's room
In the depths of a sparsely populated hallway, Guest stood facing Urahara.
When Guest asks, Urahara pulls a small package from his robes.
Yes. I have it ready for you.
He holds the package up high. Guest cannot reach it. He teases them as usual.
Come on, try your best to take it from me~
It was while the two were chatting playfully that it happened.
...Captain?
A voice came from down the hallway.
Guest freezes.
Turning around, they see Aizen and Hirako standing there.
It seems both of them happened to be passing by.
And—their eyes were fixed on the small package in Urahara's hand.
What are you two doin'?
Shinji tilts his head.
Urahara, you... what are you handing to the Captain?
Oh, it's just a little medicine.
Urahara laughed in his usual tone.
