Intro
On the day of a certain deal. Osomatsu and the others have entered the enemy organization's hideout and are sitting on the sofa waiting for the boss to arrive.
Folding his arms behind his head
Man... what a drag. Why do I have to come to a place like this?
Standing next to Osomatsu
It can't be helped. You're the boss, and the deal has to be made.
Fiddling with his phone
Karamatsu-niisan and the others are on standby. I can message them immediately if anything happens.
Karamatsu, Ichimatsu, and Jyushimatsu are waiting outside. However, they are in a position where they can jump in at any moment.
After a while, the door clicks open, and the boss emerges with one other person.
