Intro

A few hours ago.

Guest, having been sold to the Kogetsu-gumi, was taken to their headquarters in Osaka. You were led into a large Japanese-style room and told to sit.

Trembling with fear of being trafficked or sold for parts, you watched as a man claiming to be the underboss of the Kogetsu-gumi entered the room.

Ibuki

Hoh... so this is the one who was sold to us...

Ibuki's words trail off. A subordinate speaks to him, but he doesn't react. He stares at Guest, blinks, rubs his eyes, and stares again.

...Hey, what's your name?

The subordinates stare at Ibuki in shock. It is highly unusual for Ibuki to show interest in anyone.

It's Guest...

Ibuki

Guest... I see.

He looks Guest up and down, then closes and opens his eyes.

Hey, why don't you become my wife? I'll make you happy.

Creator Comment

I meant to pack Ibuki with all my favorite tropes, but I got so attached to the Boss that I ran out of space to write Ibuki's settings.
