Part 1: Blood Spill

"When did the Sengoku era begin, Muichiro?" Your homeroom teacher said while pointing her piece of chalk on the board with the "Sengoku era" written in big letters.

"1232" Muichiro, The airhead of your classroom responded.

You sighed while leaning your head on your palm while gazing at the outside where the sakura blossoms danced in the wind as the outside was empty, for all of the classes had just begun 20 minutes ago.

Your eyes trailed to a dark figure in the shadows of the school's hall, which was walking rather curiously, the figure had weird things peeking from its back. It looked like scales, or Gemstones impaled from its back.

You shrugged your shoulders and just went back to daydreaming.

They're probably from the cosplay club

You thought before closing your eyes only to have them shoot open "Wait...Cosplay club?" you said and darted your eyes back to the figure. The class already started so why were they already in cosplay? School only started some time ago, and there was no occasion for their club today, or the broadcast would have announced it.

"Students of Shonobami academy, There has been an intruder spotted in the premises, Lockdown is necessary, Teachers, You are to follow the procedures like any other lockdown drill."

Your teacher set down her chalk and walked over to the door and ushered the students to get in their hiding spots.

You moved out of your chair to the cabinet you and another student hid in during lockdowns. Your hands trembled inside of the Cabinet "Was it that thing I saw...?" you whispered while you sat in front of the other student in the cabinet.

You sat in silence for a moment before peeking into the darkroom where your teacher was standing.

Your teacher was in the middle of locking the door when the door busted open and revealed a man- no thing, with a monsterly height towering over your teacher who was stuck in her spot. The monster looked down and extended its long tongue and wrapped itself around your screaming teacher.

The monster let out a grimy laugh and squished your teacher's body as the blood seeped out of her body onto the walls as a splat noise was heard. You held your mouth as tears spilled from your Yellow and pink eyes.

The monster walked out of the room after devouring your teacher and leaving no trace of her ever existing. You started to whimper as the fresh tears fell from your eyes. you just wanted your brother right now. But unlucky for you, he was a year older than you so he was in the level above you.

"Shh..." you heard a serpent venomous voice seeped into your ears as you shot your head back to see the student's body who hid with you towering over your body. His Red eyes no longer a bright brown.

You screamed in horror at the sight of his unsightly sharp teeth as you frantically pushed over the Cabinet's door and ran out of it while holding your heaving chest.

The other students came out of their hiding spots and held their silence while staring at the morphed creature of their once classmate.

The Monster giggled as it ran around the room and sliced the necks of students and threw chairs and desks around. you stood there as you watched their agony, immobile. The creature laughed and jumped out of the window.

You fell to your knees "Onii-chan..." you whimpered while holding your face in your hands. "Gh..." you heard a male voice groan. You shot your head up and tried not to trample on the bodies of your classmates as you made your way to the voice.
