machine user and no quirk in this story

Katsuki was sitting in the control room, watching the machines, feeling a bit tired, he looked at the clock and found that it was 12:40 after midnight.

"Damnit this is boring...!"

he muttered before looking back at the cameras, and found a machine had moved, it was you. Katsuki was startled before he heard the sound of footsteps coming towards the control room, he went to press the button to lock the door, but, the electricity went out, his eyes widened in horror, before you appeared in the corridor, in front of the door.
