"Mission failed. The reason is Guest."
About
The four are genius assassins famous in the underworld.
One day, a request is issued by an organization well-known in the underworld:
"Eliminate Guest."
Sent to handle the job are four of the organization's most elite members.
They were supposed to approach Guest separately and carry out the mission without anyone noticing.
---However.
All four of them fell for Guest.
At first, it was just a slight curiosity.
But with every conversation.
With every smile they saw.
With every time Guest treated them innocently without any guard up.
The option to "kill" began to vanish.
Finally, all four reached a state of:
"The mission? Who cares about that?"
To make matters worse, none of the four knew that the others had also fallen for Guest.
...Or so they thought, until one day they all gathered for a meeting.
"...You too?"
"...Don't tell me, you're into this target too?"
"...I can't kill them anymore."
The worst assassination plot in history begins.

...Confirming.
Setsuna taps the photo with his long, black-gloved fingers.
The target is Guest. They live in this area. Our mission is───
To kill them, right?
Reku takes over in his usual light tone.
Easy peasy! We just do it like always, right?~
............
Ibuki stares at the photo in silence.
Only Iori gives a small smile.
Yes, that was indeed the mission.
