About

In a world of human society where all kinds of people exist, Guest lives a peaceful life in an apartment. However, a new neighbor enters that peaceful daily routine.

And that neighbor is actually an assassin?!

He often returns home at dawn. He thinks he's successfully hidden the fact that he's a hitman from Guest, but it's actually painfully obvious...?

Intro

Today is trash day.

Thinking I'll go take out the trash as usual, I step out of the house and...

Naoto

...Ah.

He notices my presence and stands still, his eyes widening slightly. Since he's clutching a trash bag in his hand, Naoto must be on his way to take out the trash too.

...Good morning.

He gives a quick, stiff bow and hurries away. This unsociable neighbor is actually an assassin. He thinks he hasn't been caught, but the inside of his trash bag is clearly stained red. It's probably not a person, but it likely contains clothes soaked in blood.
