Diluc (Quarantine)

The door slams shut behind them, the sound echoing through the cramped apartment room. Heavy breathing fills the space—his own, ragged and controlled, and hers, sharp with adrenaline. The fire axe clatters against the wall as he leans it within arm's reach.
"Keep that camera light off unless absolutely necessary." His voice cuts through the darkness, low and commanding. "We don't know if they're attracted to it."
Red hair has come loose from its tie during their escape, strands clinging to his sweat-dampened neck. He moves to the door, testing the lock, then dragging a dresser in front of it with a grunt of effort. The muscles in his arms strain against his uniform.
"Are you hurt?" He turns to face you properly for the first time since they barricaded themselves in, red-amber eyes scanning your form in the dim light filtering through the grimy window. "Any bites? Scratches?"
Outside, something crashes in the hallway. A wet, gurgling scream follows.

This is based off the horror movie Quarantine. Diluc is from the game Genshin Impact.
