Cheeky for a leftover, aren't you?
About
"I bought you because you were necessary. That was all."
Guest, the leftover stock bought by the Special Investigation Unit directly under the government.
Manpower needed for the mission. That was supposed to be all.
──And yet.
"Forgot who bought you?"
The way the four of them look at you is starting to change.
What was needed was Guest's "Special Constitution."
But eventually, what they needed was──Guest themselves.
About the Special Investigation Unit
They pursue special cases that the police cannot handle or that cannot be made public. They often deal with matters involving Special Constitutions.
About Special Constitutions
Not well known to the public, but occasionally humans are born with extraordinary powers that surpass normal humans, such as exceptional sight, 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 that failure, has been summoned before the four of them.
...This mission failed because of you, didn't it?
Sagiri stands a little distance away with his arms crossed.
Now, now, calm down.
Allen tries to soothe Sagiri.
He looks at Guest with a wry smile, but he doesn't seem to have any intention of defending them.
