The guards' first two shots struck Rory's shield, doing no harm, though the noise the guns made was ear-splitting. The gurads themselves must have been used to it, as they didn't finch, and neither did Marvin.
Aoife's shot to the guard's chest was met with a grunt and a stumble back, his gun now pointing towards her. Her other shot, however, took him down - one could viisibly see his dark blue aura break around him. He was still standing, but the bolts striking his legs made him scream and drop his gun. The following revolver shot put him down for good, leaving a spattering of blood on the wall behind him as he slumped against it, completely limp. The second guard was struck by the revolver shot first, causing him to collapse, while the following bolts embedded in his legs, the poor man yelping in pain.
"If I'm being honest, I wasn't expecting you kids to be so... well, cold-blooded. My mistake there," the man said, calmly. He sat up, crouching down next to the still-living guard. "Where did Whitaker blink to? No reason for this to turn any more bloody than it already is."
The man gritted his teeth, his eyes darting between the students behind Royale. He swallowed a glov of saliva in the back of his throat. "H-he probably went down to the basement level. That's where the casino is. P-plese, I have a-"
"Thank you. Feel free to call the authorities if you so desire." Marvin told the man as he stood up, facing the students once more. "We'll be heading down now. We'll likely have to fight our way through the building, and we'll need to take the stairs. Please, keep lethal force to a minimum," he spoke, digging through his jacket to produce a massive maroon-tinted handgun chambered with .50 rounds. "If you see Whitaker, feel free to move quicker. His semblance should take several minutes to recharge, and is unreliable unless he has made proper preparations as he had just now. Try and stick close, however."
As he talked, Marvin took a spot in front of the door, giving the students time to figure out where they themselves wished to stand, suggesting they take cover and signalling to them that he'll open it on the count of 3. 2. 1.
He swung the door open, stepping to the side as a barrage of bullets came flying in, four more guards on the other side. Three of them had revolvers, while one was carrying a generic assault rifle. Said assault rifle guard was the one going hog-wild and spraying through the entrance, though he soon found himself needing to reload.
