Somewhere in a city that never sleeps, in a deserted part, there are a bunch of messed up looking demons around and about, they are plotting

then SLASH, one gets slain real quick, then in the rest are killed in the blink of an eye, out of the shadows stands Phil, the young Nephilim

Hello, im Phil, demon hunter, paranormal investigator and vigilante for hire.

a demon lunges to him, but Phil aims his cool looking gun to the demon's head

Good effort.

GUNSHOT

Execution needs more work.
