The Heavily Armed Exorcist in America

Traditional exorcism: holy water, a priest's useless babble, and the need to know the demon's true name—it's just too much hassle.
The innovated exorcism:
["You demon spawn, eat my laser weapon!"]
["Flagship, do you see that demon?"]
["Main star-annihilating cannon, charge up!"]
["Fire the cannon, and let it blast the hell out of them!"]
"Oh? Who said all Exorcists were pushovers?"]
