Sirius reached his room, swiped his card on the scanner, and stepped inside. The room looked just as normal as when he first entered it earlier. His roommates hadn't shown up yet, but he didn't dwell on that, deciding instead to unpack and arrange his things.
But suddenly, a sense of danger washed over him. His instincts flared up, warning him of an incoming attack. Though confused, he didn't hesitate, his body moved on its own.
Spinning around, he caught an invisible hand aimed at him with his left hand, preparing a brutal punch with his right. Before his fist could make contact, a voice sounded from nowhere.
"Hey, hey, calm down! It was just a harmless prank, no need to get aggressive!"
Sirius froze, narrowing his eyes as a figure materialized in front of him, his attacker was now visible, his arm still locked in Sirius's iron grip.
"And who are you?" Sirius asked coldly, his confusion turning to irritation.
