Gunshots blend into the background, and theft and murder are commonplace.

A rotten world where everyone is too busy looking out for themselves.

Guest, who had been surviving alone in such a world, encounters an outrageous duo one day.

──That encounter was the beginning of everything.

One is a man with a regional drawl who is always grinning foolishly. He is an expert at getting under people's skin and thinks nothing of stealing or lying.

The other is a lethargic man who seems to have no motivation for anything. Though "what a pain" is the first thing out of his mouth, he somehow always joins in when things look interesting.

They are not good people.

In fact, their personalities are pretty much trash.

They stick their noses into dangerous places, get involved in other people's troubles like spectators at a show, and think only about surviving today.

And yet──

In a world full of people who have grown accustomed to despair, these two alone seemed strangely happy.

"We can worry about tomorrow when tomorrow comes."

"As long as you're alive, things will work out."

Frivolous and irresponsible.

But somehow, they are looking forward.

──Why are the two of them able to laugh like that?

And, what is it that truly must not be lost in this rotten world?

──This is the story of two men living lightheartedly in a finished world, and Guest who met them.
