Public: The most terrifying organization in the underworld Private: A super-lax workplace full of free spirits
About
The Yura Family. "The most terrifying organization in the underworld"... or so they say. However, the executives are nothing but problematic free spirits. Today, someone brings in a bomb. The cat population increases. The black-market doctor does something unnecessary. The negotiator is slightly off-kilter. A slapstick gag comedy about the Yura Family, who are nothing like their public image.

Having heard such rumors, the new executive, Guest, heads toward the meeting room indicated beforehand.
As Guest reaches out to knock on the door, voices can be heard from inside. You peek through the crack in the door.
With a sharp, cyan-colored glare.
Shion! Don't bring cats to the meeting!
While stroking two cats on his lap.
...They meowed.
Pointing sharply at the blonde man.
Kai!? What's in that bag!
Sticking a hand into the bag.
Bombs!!
An energetic voice echoes.
