The notes

Hakura and Zenno just got back from the track meet, Zenno walked off waving Hakura goodbye, Hakura stayed a little longer to practice, As he feels more like himself when he is running along the red oval track, He decided to head back to his locker to change into his outdoor shoes, As he opened his locker he sees a note written in red ink, It reads “Tell them what you did Hakura.”He brushes it off, He thinks it's a prank Zenno wrote in his locker.
changed to Zenno
He is walking home looking at this teared up piece of paper from a note book. He can't shake the words written on this note in blue ink, it reads “I remember everything.” He waits at the bus stop thinking about the track meet trying not to overthink this note. The bus had arrived and he threw the note inside his bag and headed onto the bus.
Changed to Yuri
She is at her family's diner, working as a waitress, serving all different types of people. One customer ordered Omurice, another customer ordered Gyoza. There were a lot of customers at the end of school, “Yuri!.” her father yelled from the kitchen. “Yeah, need some help back there?” she replied in a sweet tone!, he nodded and she went to the kitchen to help out!. A few hours pass. The old man who ordered the Gyoza finished his food, thanked the staff and left the diner after putting on his shoes talking about how amazing the meal was. In the corner of Yuri's eye she saw a girl around her age in the corner booth staring at her. After they locked eyes the girl called the waitress over to collect her dishes, Yuri smiled and walked over, “did you enjoy your meal today!” Yuri asked the girl, smiling, the girl passed over the plate and walked off without a word. Yuri was confused by that interaction and thought she didn't like the Omurice. Under the plate was a crumbled up piece of paper with Yuri's name on, she slipped it in her pocket and acted as if nothing happened.
AI and sora are at soras house 
AI were sitting on the floor with her laptop on the table showing Sora a video she had taken a few weeks back, for a project for her media class, the rain started to pour “it's raining cats and dogs out there! looks like I'm staying over tonight!” said AI laughing they turned off the lights to give a cinematic effect, as AI made a short horror film with her classmates, they play the film, it begins with an empty, abandoned looking hallway laughter in the background, AI saw something unusual in the background, she paused it and zoomed into the spot and enhanced the lighting to see it clearer an unknown shadow had appeared in the background, something she didn't plan to do, Sora didn't know this and thought this was part of the sequence, AI leaned back and gasped! “no…no it can't be?!..” Sora got scared and responded “WHAT?!?!” Sora's phone buzzed, they both got scared, “unknown number” appeared on the screen, they opened the message, no text, only a photo, from the video they are watching, another text came through as the girls stared at each other with fear, “you missed something!” another text comes through, “check your bag!” She goes to check her bag, nothing out of the ordinary, note books, pencil case, her glasses, but there was something sticking out of one of the note books. a torn up piece of paper it reads with black ink ‘’that wasn't an accident was It?” 
Changes to Kaito 
It was quiet in the library, and Kaito went to study. He is the baby of the group, a year younger than the rest of them. He sat at one of the far tables in the library, but he couldn't focus, he mumbles to himself “focus.. I need to study.” Every now and then he would look up, not being able to shake the feeling of being watched, no one was there. He tapped his book trying to come back to reality. A book fell from somewhere in the library, the noise was sharp and loud. “uhm hello?..” Kaito spoke in a soft tone. no answer, “must have just been the librarian again…” he went over to the noise thinking he would find the librarian and help her out like he usually does. There was a book on the ground, no librarian, no one around, Kaito went to pick it up and put the book back on the shelf, something fell out of the book so he picked it up and yet again, it was a torn up piece of paper from a notebook, written on this note was “the truth will be revealed.” he put it inside his pocket and messaged the group chat 
the group chat is called the chaos crew
Kaito : “hey besties!!!”

Hakura : “whats up?”
