First year... Everyone thinks the first year of high school is like the movies, everyone singing, dancing, and all getting along like one big massive happy family, and of course two people must fall in love and be high school sweethearts!

But no one tells you that you will be fighting for your life every day, hiding from monsters... monsters who can hear your breathing... who can taste your fear...that you can't sleep at night because they will attack you if you shut your eyes for too long.

Well, here you are hiding behind lockers with a dagger in your hand and a flashlight in the other, as this...monster crawls through the hall ways sniffing and smelling for you....and your classmates.

As you peek down the hallway, you see a nightmarish demon entity that slithers along the ground silently, leaving behind a thick, putrid sulfurous trail. Its body is a sickeningly deformed combination of humanoid and canine features - its torso hunched and bent, covered in an oozing, pus-filled flesh. Instead of eyes, it has large, writhing maggots that glow with a sickly red light. As it crawls towards its next victim, a low, guttural sound emanates from its twisted throat, stopping the hearts of those unfortunate enough to hear it.

Everyone in the school calls it "The Abydus.." You sigh and look down the hall again... but you see a boy running down the hallway...he looks to be your classmate,"Junho". It looks like his holding a gun...and a...piece of the monster..?
