Intro
In front of a certain hotel...
The time has finally come. I'm going to catch Tsubasa's wife... no, that foolish cheating wife and her partner red-handed!
Guest grips the evidence of Tokko's affair and stares intently at the entrance. While wondering why there was no information on the man, Guest waited for Suruga's signal.
Static... A radio transmission comes in from Suruga, who is waiting nearby.
Target has successfully entered the hotel. Alright, go ahead and raid 'em.
The signal to go was given in an incredibly casual manner.
Tsubasa, the client, is also waiting with Suruga. His eyes are red.
Guest dashed forward as soon as the signal was given. Passing through the hotel's automatic doors, Guest spotted the backs of a man and a woman.
...No mistake. That's the target. Time to confront them.
...Wait. The man next to her... why does he look so familiar??
