Chapter 1

BEEP BEEP BEEP BEEP…

Katsuo woke up to his loud alarm, quickly shutting it off just to get it to SHUT UP. He then practically jumped out of bed.

"Yay. My first day of school. Boring classes. Annoying people. Bullies. Homework."

Katsuo put on his clothes and packed his backpack. He walked out into the kitchen, drawn in by the smell of food.

"Hey sweety, I made pancakes!" Katsuo's mom said as he walked into the kitchen.

"Ooh, pancakes! Gimme gimme gimme gimme gimme-" Katsuo was cut off by his mom. "Katsuo, calm down."

"Oops, sorry mom," Katsuo replied, "Can I have the pancakes please?"

"Yes you may Katsuo." Katsuo's mom replied.

"YAAAY!" Katsuo yelled as he dashed towards the pancakes and started wolfing them down. "Done!" Katsuo then gave his mom a hug, and then sprinted out the door, and started running towards Kunugigaoka Junior High.

When Katsuo got to the school he remembered something preeety important.

"How the frig did I forget that I have to walk up a GIANT FRICKIN MOUNTAIN TO GET TO CLASS!"

What he didn't notice was two kids from the main campus walk up behind him and try to shove him, though both of them must be pretty weak 'cause they could barely get Katsuo to budge.

"Oi! The frig you think you're doing?" Katsuo yelled to the two nerds when he turned around.

"We're simply getting delinquent trash of the main campus." The chubby one said.

"Oh, I'll show you delinquent!" Katsuo yelled as he grabbed the chubby one and punched him in the gut. He then dropped the nerd to the ground, turned around and started his hike to the satellite campus.

"Stupid cocky main campus crapholes." Katsuo thought to himself as he walked up the large hill. Before he knew it, he was already at the satellite campus. He went inside and walked to his designated class, class 3-E. When he walked in, he immediately noticed a few certain people. There was a boy/girl (he couldn't tell) with ice blue hair and eyes, a girl with green hair that was in a cat ear hair do. There was also a boy with red hair and amber eyes, and a boy with blonde hair and bright blue eyes. Though the person that he thought was the most noticeable was a girl with brunette hair and one eye that was red and the other was grey.

"She's kinda cute…" Katsuo thought as he went and took an empty seat. That's when Katsuo finally took a good look at the teacher/target: a bright yellow octopus with a permanent smile, beady little eyes, and he was wearing a large teacher's robe.

"Ah, you must be the new student. Your name is Katsuo, correct?" The teacher asked. Katsuo just sat there, not moving.

"Um, are you okay?" Koro-sensei asked. The entire class turned and looked at Katsuo, who was unmoving.

"Karma, can you please check on him?" Koro-sensei asked the red-haired boy.

"You got it chief." Karma said as he walked over to Katsuo. He then tapped his shoulder, and Katsuo disappeared in a puff of smoke. At that same time, a humanoid shadow suddenly appeared behind Koro-sensei and plunged an anti-sensei machete in his shoulder.

"Sup." Katsuo said as the shadows around him disappeared. This sneak attack took the entire class, including Koro-sensei, by surprise. Koro-sensei then dashed to the side using his Mach 20 speed to avoid getting hit again.

"H-h-how did you do that?!" Koro-sensei asked, still trying to figure out what just happened while his shoulder grew back.

"It's a martial art technique. I can move at a speed of up to Mach 16 when I actually try. I can also leave behind a perfect shadow clone of myself when I use the technique. I also can't be seen when using it, making it seem like I teleported." Katsuo said as he put the anti-sensei machete in a sheath on his belt. "It's apparently good for landing a hit on you."

"Very interesting. I've never heard about a technique like that. In fact, it is quite impossible for a human to move at speeds over Mach 3 and live. The friction from the air would cook you alive at speeds like that. However, I suppose impossible things happen a lot at this class." Said the blonde boy, before he absently pulled out a kusarigama and started whirling it around, nearly hitting the students around him. The boy then suddenly jumped before standing up and moving in front of Katsuo. "I apologize for speaking before introducing myself Katsuro-san. I am Kayaba, Akihiro, also known as Aki.

"If you do it right, a human being can easily survive any speed. You do it by using something hard to move the airflow around you; in my case, my normal machete." Katsuo replied.

"If you two could please take your seats, we could get started." Koro-sensei interrupted before either students could say anything else.

"Got it." Both students replied.
