The instant the demonic beasts materialized, the members of Clan Calatin inside the station should have sensed their presence and made for the office. With five of them, including the real Vera, he would be able to gain the upper hand, even against a genius and his Servant.
The question is, can I hold this Servant off until then...?
At that point, the chief ’s eyes widened again. A second, identical figure was standing beside the fake subordinate he was pointing his sword at.
“Please abandon your offensive posture, Chief of Police Orlando Reeve,” the thing that seemed to be Flat’s Servant stated dispassionately in tones identical to Vera’s.
Two more identical figures appeared in the room in the span of that brief sentence and pointed at the monitor on the chief’s desk. The chief pulled away from them, shooting a glance at the monitor as he leapt back. What it displayed astonished him.
Every camera showed Orlando Reeve and Vera. They were in multiple places, explaining something to the various members of Clan Calatin individually.
This... isn’t image modification. It’s disguised as Vera and me...? As this many of us?!
The Heroic Spirit in Vera’s shape spoke, as if in answer to the chief ’s doubts.
“The population of this police station is now forty percent me.”
The chief looked at the Heroic Spirit and at Flat and silently sheathed his sword.
