At the small City of Arcadia, a 17-year-old boy named Sazato Kanzahiro has now begun his Twelfth-grade school after the end of 2018.
While entering the classroom, he noticed, he is the only one that has got into the classroom, as he waited 6 and a half minutes, he noticed another boy that was peeking at the window, he went out of his classroom and decided to check it, but unfortunately, the boy ran away as fast, Sazato didn't want to chase that boy and rather wait at the classroom, but he still decided to chase the boy. Sazato nearly grabbed the boy, suddenly, he tripped, there was nothing blocking his way, he questioned himself "How did I trip? It's probably because I went too fast. ". He decided to go back to his own classroom and leave the boy alone. But as soon as he opened the door, a person was already in, the person greeted Sazato, "Hello, My name is Notani Hinji, and yours is? " Sazato stood there for about 2 seconds and replied with "Ah, My name is Sazato Kanzahiro, I guess... Nice to meet you? "After Sazato replied and greeted Notani, they both stared at each other for about 1 and a half second, then Sazato sat back to his seat. After 5 minutes, Nobody came. Sazato Questioned, "Why is nobody coming?" And Notani kept quiet. Sazato looked away at Notani and stared outside the window, he saw nobody at the gate, but he remembered the Gym Teacher was there. Later then, He heard a loud thud, he looked at Notani but he noticed, Notani was gone, when Sazato opened the door and left the classroom, he noticed everybody was there, he went downstairs to the gate, and he saw the Gym Teacher! He was so confused, he asked himself "What the hell is going on?" About 2 seconds of staring at the gate, Notani suddenly gripped Sazato's Shoulder, Sazato lightly jumped as Notani's hands have touched Sazato's shoulders, Sazato turned around, scared, suddenly, he saw it was just Notani, Sazato said, "Phew... You scared me, Notani." Sazato and Notani went back to their classroom, and as they opened the door, nobody was there again, Sazato pulled Notani in, and actually asked, "Did you hear any thud or something in here?" Notani Replied, "Uhh. No, I didn't hear any loud thuds or anything. " Sazato was freaked out with Notani's reply, Sazato said something with a frightened face, "O-Ok..." Notani asked, "Why are you frightened? Did something happen?"
Sazato replied "N-No, its nothing. " a few minutes later, Sazato suddenly woke up, he'd sigh as he realized it was just a dream. Notani Said "Oh hey Sazato, your awake now! While you were asleep, everyone came in, so, our classroom is full now!" Sazato said, "Oh uh, eh... Erm... So... where is the teacher, actually? " Notani replied, " Exactly expected for you to ask that. all of us were thinking why our teacher isn't here yet, but we looked at all of the classrooms, all of the teachers are gone! even the Gym Teacher, but only the Guidance Counselor is here, but the door to the Guidance Counselor's room was shut. " Sazato stood up his chair and ran to the window, he noticed the gate was still open.
