Somewhere deep in a forest... A young girl was sitting in a middle of a small grass area covered by trees, she had nothing on her but a piece of stick next to her. She had her eyes closed breathing slowly. But the. Suddenly arrows come flying towards her. She opens her eyes grabbing the stick to hit the arrows away from her. Then a big log comes flying in to her. She jumps up onto the log and stands on top of it. Knifes come flying along with spears and more logs. She knocks a few of the knives and grab two and jumps up to a tree heading towards a cliff by jumping one to another branch. Then she jumps to the side of the cliff and starts to jump up heading up the cliff. After she got up a shadow attacks her with a sword. She quickly grabs the knife she got from before and blocks the attack. She slips under the attacker and quickly goes behind and holds on to the arms and puts a knife just in front of the neck.

"You got me there, Kiriga.." The attacker spoke.

" Too easy for me" she said.

"Long time ago in Japan they were said to be special warriors who served under the daimyo during their times. These special warriors were capable of doing anything, even though serving under the daimyo they had jobs, not going into war or selling products but their jobs were...assassination. It was said that they could control natural elements and do what no man could but these people, they were trained ever since they were able to walk. They were called...shinobi otherwise known as ninja's."

"Koro sensei that's ridiculous! You can't be serious that they actually existed." Maehara, flicked through the pages of the history book that koro sensei was reading to the class.

"Of course they real! " korosensei who was a big fan of Ninja's quickly went up to Maehara's desk and showed him of a sexy model that wa wearing ninja clothing.

"Sir...that's a cosplay you know..." Maehara looked down to the picture" Of course, but it's written in so many history books they must be real! "

"Sir why do you like ninja so much?" Nagisa said.

"It's obvious isn't it? They are so cool! You kids don't understand how ninja's are great do you?" Koro sensei has the green and yellow striped face on,which meant that he was looking down on to the students of 3-E.

"Sir I think that your too old for these childish dreams don't you?" Karma the trickster snickered."

"Wha? I am not childish!"

"We'll I'm sorry We were just trying to be mature unlike a immature teacher like someone here."

"Karma! " Koro-sensei's was red which meant angry, of course he wouldn't ever lay a finger on his students but he could always do makeup on his face with his Mach 20 speed.

Just about koro sensei was going to explain the coolness of ninja's a ball came falling from the ceiling making it explode smoke.

"What?! Smoke screen?!" Everyone was panicking especially Koro sensei.

"Got ya..." A voice came from next to him. The next thing he knew he was wrapped up in a tight rope.

"What is happening right now?" Nagisa coughed trying to see what was happening at the front.

"Wait please let me go?!"

"Koro sensei what's happening at the front?!" Isogai shouted.

"I will quickly blow away the smoke with a fan" Ritsu the AI got out a huge fan from her box blowing away all the smoke away from the classroom revealing what was happening at the room, then Karasuma came in.

"Hey octopus, have you seen the new transfer today? ...what the hell are you doing?"

Koro sensei was tied up and there was a girl on top of her with a knife at his heart.
