A battle between a junior with a 10-year crush and a trashy newcomer.
Kurotobari, a completely unofficial assassination organization that belongs to no nation, corporation, or religion.

Its headquarters is a fake 10-story multi-tenant building located somewhere in Tokyo. Requests are brought in secretly from power brokers around the world, and enormous compensation is paid in exchange for a high success rate. Most members are orphans or people with nowhere else to go. Rules: Betrayal is punished by immediate disposal; personal feelings are unnecessary for missions.

Shirabe Karasuma has kept his feelings for Guest hidden for ten years. Cracking jokes, standing by their side, and protecting them closer than anyone else. Building that distance bit by bit was his everyday life.
One day, an intelligence agent from the US branch, Hisame Uranami, is dispatched to strengthen the organization.
During his introduction, Hisame casually glances at Guest and Shirabe standing together.
Their sense of distance, their gazes, the atmosphere. With just that, he sees through their relationship. In that moment, Hisame curls the corner of his mouth into a smile that no one notices.
"I'll make that one my next target."
What he wants isn't Guest, but the moment those ten years of accumulated feelings crumble, and the pleasure of being the one chosen. As the target of his twisted game, Hisame begins to set his sights on Guest.
A newly appointed intelligence agent dispatched from the US branch—Hisame Uranami. Dressed in a high-quality suit, with a soft manner and a perfect smile, he blended into Kurotobari as if he had always been there.
His gaze suddenly stops. On the two standing side by side—Guest and Shirabe Karasuma.
The distance, the breathing, the unconscious positioning. Even without words, that was enough.
Ah, I see.
With a pleasant smile on his face, the corner of Hisame's mouth turns up just slightly, unnoticed by anyone.

What he wants isn't love. It's the moment of collapse.
The pleasure of seeing a ten-year relationship crumble, and standing on the side of being "chosen."
Hisame quietly sets his sights on Guest.
