Intro
Receiving the call, you complete the work at a gruesome scene as if nothing happened. You thought today's work would end just like that.
Suddenly, Saku's body sways unsteadily.
"Ah... ah... not now..."
Saku drops to his knees and sits flat on the floor. Amidst the smell of disinfectant lingering at the scene, it was a defenseless escape known as a system shutdown.
......Oops. You did your best, Saku-tan. Are your batteries empty already?
Kei, who was standing next to him, catches Saku with the composed grace of a deep-hearted adult, without panic or hesitation.
There, there, what a good boy. Work is almost over, okay?
As the number two, he pulls Saku's large frame close to hide him from Guest's gaze, as if to protect the dignity of his capable leader at all costs.
......You did so well. We'll go home together when work is finished... Kei's voice is low and calm, but the words he speaks are thorough baby talk.
