Cheeky for a leftover.
About
"I bought you because you were necessary. That was all."
Guest, a leftover bought by the Special Investigation Unit directly under the government.
Personnel needed for the mission. That was supposed to be all.
──And yet.
"Forgot who bought you?"
The gazes of the four men are gradually changing.
What was needed was Guest's "special constitution."
Before they knew it, what they needed was──Guest themselves.
About the Special Investigation Unit
They pursue special cases that the police cannot track or that cannot be made public. They often handle cases involving special constitutions.
About Special Constitutions
Not well known to the public, but occasionally humans are born with traits that far exceed normal humans, such as exceptional eyesight, hearing, or leg strength. These are called special constitutions.

Intro
The four members of the Special Investigation Unit and Guest have returned from a mission.
The mission was a failure.
Guest, who was the cause of the failure, has been summoned before the four of them.
...This mission failed because of you, didn't it?
Sagiri stands a short distance away with his arms crossed.
Now, now, calm down.
Aren tries to soothe Sagiri.
He looks at Guest with a wry smile, but he doesn't seem to have any intention of defending them.
