Magic is real?

  After the return of class 1-E's beloved Koro-sensei, the teachers decided a small vacation wouldn't hurt and they pulled strings to ensure the world wouldn't bother them. Nagisa couldn't believe his luck at the teachers strength and kindness. 

    It was a wonderful day at the beach. The waves were splashing, the wind was blowing.. Who would have thought that at the day Koro-sensei resurrected...

SOMEONE WAS TRYING TO KILL HIM!?

   "Chotto matte minnah!!" Nagisa cried trying to stop whoever was going against their teacher, despite the fact he was their beloved teacher who they loved and feared.

   "What's wrong, Nagisa? We ain't doing anything," Replied Karma who laid back on a beach towel, happily sipping from a smoothie. 

   "Then....Who's shooting Koro-sensei?" Nagisa wondered out loud.

   Everyone turned around as the sound of Koro-sensei's scream came rolling into their ears. They managed to spot a girl with red long hair and orange eyes gleam with a smirk as she had sat on top of Koro-sensei.

   "Konnichiwa, Koro-sensei... You should have been swifter... But then again, you just came back," She muttered while pulling out a gun and pointing it at his head. "Be prepared.." 

   'N-No... T-This can't happen again,'  he gasped in surprise before standing up in a rush.

  "MATTE!!!" Nagisa screamed at the top of my lungs as the trigger was pulled but instead...

A boutique of flowers was shot out....

   "Here you go for your resurrection!" The girl cheered while offering it with a smile. 

   They were all astonished as the girl gave a nice warm smile instead of a glowering scowl as suspected. She had a happy look as she got up and helped their teacher to his feet. 

   "Wait a second... Who the hell are you?" Karasuma asked. Before he could take a step forward, Karasuma was halted by the out-stretched arm of his red-hair student, Akabane Karma.

   "Hold it, Karasuma-sensei," he muttered softly.  "Y/n onee-chan... What are you doing here? Didn't the government capture you?" Karma questioned

'WAIT?! ONEE-CHAN?! When did Karma have an onee-chan?'  The girl had a sad emotion on her face and she said something that made Karma mad.

"I don't know you, You must've mistaken me for somebody else..." She replied sadly

Karma gave Y/n a slap and had tears in his eyes as he yelled, "You ARE my onee-chan!! Don't lie!!!"

    "...I have no relationship with you.." She huffed while avoiding all eye contact with Karma.

  "Grrr.....IMMA KILL HER!!!"Karma roared in anger.

    "Calm down Karma!!" Okuda pleaded while holding him back.

 'Why would a sister lie about her life with her  brother?...What is her motive?' As the question's bombed into Nagisa's head, Karasuma -sensei stepped forward and stated something important.

     "That badge you're wearing is for assassin's ONLY...Who are you?"

     She blinked out of concentration for a second before she grinned slyly insight of the elder man. "Let's play a game Karasuma-kun..."

   "Huh?" They all blinked in confusion of her sudden suggestion.

    "If your knife even gives me a tiny scratch, I'll explain to you EVERYTHING! Let's play a KNIFE battle!" She announced simply while tossing a knife at his feet.

'A KNIFE BATTLE BETWEEN KARASUMA-SENSEI AND Y/N AKABANE?!'

"And if you lose, you will serve me, In a BUNNY costume!" added the red hair girl with a grin.

  'WAIT,WHAT?!?!?!'

     Karasuma-sensei sighed while rubbing his sore temples at his nose bridge before finally giving a nod as a sign of agreement. 'This is going to be wicked!' They all gasped in disbelief.

(A/N: So I've began to rewrite this for the sake of my viewers who want me to continue this. But the problem is, I need to change it to continue it cause it seems so childish. I apologise if it seems completely different than my first version and I promise I'll do my best to make it seem good enough to rival my first version... )
