The Unseen Red

A complained

Nagisa wasn't the only one watching Karma. At the front behind his desk , Korosensei also had his round eyes on the transfer student. His face was a normal yellow , meaning no particular emotion or other , but though there was a fixated smile on his face , Nagisa could tell that the teacher was at least the tiniest bit wary.

The creature sighed and stood up. "Now everyone.... " Korosensei was moving at Mach 20 , a blur of motion. "....shall we begin?"

"..Begin what exactly ?" 

The class stared at him dumbfounded.

"Midterm test is coming around that's!! Did you all forget ?! That makes me so sad!!" Korosensei yelled while drying his fake tears.

Okajima shrank in his seat. "Oh, crap...."

"Yes , that's right !" Isogai exclaimed.

Fuwa sighed. "Wow....this gonna be fun.."

"And that's why this period....." Korosensei sped up. "Will be spending your time and focus on your study !!" The class gasped when he suddenly appeared at each one of their desks. "My doubles cab work with you one-on-one to drill you in each of your worst subjects."

"...is it bad that this really not surprising me too much ?" Kataoka said aloud , raising an eyebrow. "Like , this guy could randomly turn into a talking dog and i'd be completely fine with it."

Sugino cross his arm and lean his head on the desk with his head on top of the other. "I agree."

"But that guy behind us is much more than the creature in front of us." Meahara pointed behind , their attention turn to meet Karma who's paying attention to the notes with Korosensei's clone disappear and reappear infront of his desk.

Nagisa nodded slowly , blinking owlishly. "Y-yeah...."

Terasaka wasn't impressed by Korosensei's move. "Ridiculous. He even switched headbands for each subject," he grumbled. When Korosensei appeared in front of him , the boy glowered but then gasped when he saw the teach had a familiar headband.

"HEY! WAIT A MINUTE WHY DO I GET A NARUTO HEADBANDS ?!?!" Terasaka complained.

Nagisa watched the teacher speed up. Fuwa tried to keep up with Korosensei's gibberish. Suddenly a dent appeared in Korosensei's face , making Nagisa jump.

" Waoh !" Nagisa exclaimed in shock.

"No sneak Assassinations if you please Karma-kun!" Korosensei scolded. "Dodging interferes with my ability to maintain steady images!! " 

Karma had his knife raised , sticking out his tongue.

"These doubles are so fine and delicate," Nagisa said. "But, do you have any strength left after making them ?"

"Not to worry !" Korosensei looked at him. "I have a double resting outside."

Nagisa blinked , blankly. "Huh ?"

He looked over at Karma who gesture silently beside the window , his eyes did not leave the papers that he was holding. Nagisa turn to the direction where Karma was pointing , outside there was a double sunbathing near the window with Korosensei clone , resting.

"How is that helping ?!" Nagisa yelled.

"But with exams looming...we're glad to have him as a teacher." The bluenette smile proudly as his teacher continue to mumbled about the study question."No matter how you slice it, he's the one tricky target for us killers."

The scene shifted to the staff room where Principal was holding a Rubix cube.

"Gakuho" known as the Principal twisted the cube around to align the colors. "Let's say you want to solve this puzzle cube as quickly as possible with a robust method anyone can use."
