An Unexpected Upgrade (3)

"We've got a doll on the loose," shouted one of the guards outside Gray's room as he saw the blue-haired girl flee from it.

Gray bolted out of the room, using the distraction created by the girl to his advantage.

The sound of concrete being scraped filled the hallways as Gray sent waves of red energy towards the guards, severely cutting anyone foolish enough not to step out of its way.

The smile on Gray's face only grew wider as everyone in the building looked around in confusion, wondering what was going on.
