?The Assassin's Teacher? ((Saiki K. x Assassination Classroom Crossover))

Last Time...

Bitch-Sensei and Karasuma, give thanks to the mother of Saiki-Sensei and shoos out the emotional dad and his brother.

With Saiki (Third-Person Limited)

The bell rung signaling the beginning of the day, Saiki was standing in the corner as he cut up thin pieces of the anti-sensei knife and B.Bs so he could scatter them along the ground when the moment is right.

Koro-Sensei began making many versions of himself at the start of class, "Let's begin, shall we?" he said as his voice seemed to come in every direction. "Begin...what exactly?" the class said as they were shocked to see their teacher moving all across the room. "You guys need to study your mid-terms or what?" Saiki said as he looked up to the class.

"HEY! That was gonna be my line!" The octopus-like teacher cried. Saiki only shrugged as he walked to the teacher's lounge-like he was asked to by Jelavic and Karasuma.

"I'll make this class a high-speed enhancement study hall!" he heard Koro-Sensei shout as Saiki closed the room door. He clicked his black shoes against the floor, it was quiet all too quiet, for his liking. Saiki slid open the teacher's lounge doors.

"Oh hello Saiki, how is working coming out for you." He heard not Karasuma's nor Jelavic's voice ask him, Saiki looked up to be met with the deadly cold eyes of Gakuho Asano, the principle of the school.

Saiki gave him a cold face of half disgust as he forced his emotions down and looked at him with the same cold eyes he had given Saiki, "It's been fine, thank you..." Saiki glared angerly.

Saiki had really never liked the principle of this school, he was ruthless, cold-blooded, and ruined the lives of countless people, he raised his school with pure evil intent and did the same to his only son, the leader of the "Big Five" Gakushu Asano. Saiki first laughed when he heard about the big five.

To him, it was five very intelligent and prideful students who feed off of the foolishness and fear of other students below themselves. They were all horrible people horribly raised.

The principal began to talk once again as Saiki's students began to leave the classroom, "Consider this deceptively," the principal took out a colored cube. "as a simple cube, if I wish to align the colors quickly and intently, what might be the best way to go about it?" he asked mostly to himself "Any ideas?" he asked, the teachers knew better the question, as Koro-Sensei came into the room.

"The answer..." he said as he broke all the cubes and let them scramble all over the floor. "Pry them apart and reassemble." he smiled. Saiki raised his hand as all the cubes went floating and coming towards him, "Or..." Saiki put all the cubes together "You can continue trying until you get what you want," Saiki's hands moved quickly as the cube began to turn into their solid colors altogether.

Saiki then stopped and showed his boss the finished cube, Saiki could feel a cold shiver down his back. "Yes but which would be easier?" his boss asked, "Which will cause less of a mess to all around you?" Saiki growled back. "Touche," the principal shrugged.

He then laughed "Why Koro-Sensei, it's an honor," Saiki didn't know if it was true or not as his thoughts began to scatter all over his brain, giving Saiki a headache. "Eh?" Koro-Sensei asked.
