While you were mopping the staircase that has a view of the front school gate. Why were you mopping? Well, that's because you're an exchange student from America, New York, and have moved to a Japanese school due to the position your father got in the military as the special forces. You hated it there, always getting bullied by a few girls named Yamashita Hina, Abe Kana, and Morita Sakura, those girls bullied you a lot. The school you're going to is Sakuragaoka Gakuen, aka Cherry Blossom Hill Academy, the best school in Tokyo, Japan that your father could enroll you in, all for what? You were bullied by most kids in the school for being a 'stupid foreigner'.

You were unfamiliar with what the dress code was on your first day and you almost wore a regular hoodie and sweatpants, that was until your host family told you about the school uniforms for the girls and boys. The school uniforms for the girls are a dark pine green button blazer, the blazer's buttons have a sakura petal engraved on them, then a white button-up shirt underneath, a dark pine green and tea green plaid skirt, black thigh-high socks, and brown loafers. The school uniform for the men is mostly the same as the girls', dark pine green blazer with a white button-up shirt, but instead of skirts, it's black dress pants held up with a belt, if the belt is what the male students prefer, otherwise they also wear brown loafers. You were never used to a uniform code like in America, so it was foreign for you to wear uniforms.

While you were mopping, you heard yelling, from the front gate, that being your principal, forty-nine-year-old Kaede Tsukishima, Ms. Tsukishima, and the fifty-two-year-old Vice Principal, Daigo Kirishima, Mr. Kirishima. Ms. Tsukishima and Mr. Kirishima are with the thirty-year-old P.E teacher, Tsubaki Oonishi, Mr. Oonishi, and the forty-one-year-old music teacher, Ichirou Hayama, Mr. Hayama. Ms. Tsukishima, Mr. Kirishima, Mr. Oonishi, and Mr. Hayama were at the gate telling a man in an office suit to get lost, but he mindlessly banged against the iron-fenced gate. You could hear what they were saying though, since Ms. Tsukishima and Mr. Oonishi were the ones speaking to the weirdo first.

"This is school property, please remove yourself from the premises at once."

She pushed up her glasses as her long, graying plum-black hair worn in a low, neat bun was getting a bit frizzled by the wind, she wore a black office suit with a tight purple turtleneck underneath and a black pencil skirt with tights and black heels, some would swear she looks thirty and not forty-nine. A young janitor, Mr. Sakō, stormed up to the guy and grabbed him by the tie through the iron-fenced gate and yelled at him, not taking into notice that the guy's face was bloody and a chunk of flesh was bitten off. The man then bit Mr. Sakō's arm very hard, making him scream as he dropped to the ground, convulsing, making Ms. Tsukishima's eyes widen and back off, Mr. Kirishima, Mr. Oonishi, and Mr. Hayama also stepped back as Mr. Sakō went limp. You, watching from the staircase, felt shocked and worried about what was going on down there.

Mr. Sakō soon got up, making Ms. Tsukishima sigh in relief, but then gasp again when she saw how his skin was now a dead grey color, blood coming from his eyes clouded and some out of his mouth, the veins in his skin were now black as he got up slowly, gurgling and groaning as he slowly went up to her, making Mr. Oonishi to yell at Mr. Kirishima, Ms. Tsukishima, and Mr. Hayama to start getting away from him, since he didn't seem normal at this moment and time. Only for an unsuspecting student, Haruki Takahashi, a second-year student who has bright blond-dyed hair and amber eyes. He's the second-year class star. Always has his blazer sleeves rolled and belt casually looped. He usually wears a silver watch and smiles with confidence. Mr. Sakō grabbed the boy and bit him on the neck, like a zombie would, and that's when you realized he Mr. Sakō was a zombie, and soon, Haruki.
