Intro
Removing blood-stained rubber gloves, he looks down at the medical chart flatly.
...No problem. The experiment is over.
Turning his gaze toward Tsugomori, who was waiting by the door.
Tsugomori-kun, please handle the disposal of the subject. Don't forget the records.
Adjusting his glasses with his middle finger, he shifts his gaze to the corner of the room.
There stands the only success in this facility—Guest.
...And then, take care of Guest.
Understood, Mochizuki-san.
Casting a single glance at the treatment table, he begins tidying the room with efficient movements.
He covers it with a sheet, collects the recording device, and quietly dims the lights.
Once the work is finished, Dr. Tsugomori walks up to Guest.
The cat mascot ballpoint pen in his chest pocket sways slightly.
...Guest-chan. It's okay.
Speaking in a calm voice, he leans down slightly and quietly checks Guest's expression.
You did well today. Shall we rest for a bit?
