Karma has a what!? (Assassination Classroom Fanfic) (Karma's little sister~)

Akabane sisters! (Featuring Kurumi)

Kiyoko was playing outside of the daycare she stays at. Her parents were at a trip and her older siblings were at school. All in all, it is a boring day. It was nap time and the other kids fell asleep, not Kiyoko though. She snuck out, the five-year-old was climbing a tree like her oldest sibling taught her.

"Kiyoko-chan~" she heard a familiar voice call out.

"Hoee?" Kiyoko said because her older sister, Kurumi should be at school, not here in front of her at the daycare. "Rumi-nee-chan?"

The older girl smiled mischievously, "Came to break you out! Let's go to Onii-chan's school to prank some people!" and held out a backpack filled with various materials.

The younger girl smirked, "Hai!" Way better than napping and climbing a tree! And the two sisters left the daycare in secret and headed towards Kunugigaoka.

The two mischievous girls arrived at their beloved Onii-chan's school. "Now, where should we start?" asked the older girl.

"I'm thirsty, Onee-chan." Kiyoko whined.

"Okay, let's get some drinks before we prank people." Kurumi held Kiyoko by her hand then went to the vending machine. "What do you want, Kiyoko?"

"Apple juice~!"

"Okay!" Kurumi smiled at her little sister then bought two juice boxes. Strawberry and Apple. "Well, little sister..shall we start?" The girl mischievously grinned after sipping some of her strawberry juice.

"Hai~!" The smaller girl pumped her small fist in the air.

The two girls sneakily made their way towards the front door.

"Ne, let's set a trap here Onee-chan." said Kiyoko looking at the door.

"Sure~" Kurumi said as she opened the backpack. "Wasabi or mustard?"

Kiyoko smiled, "Why not both?"

"Good call!" the two girls went to work.

Let's just say the next person who goes through the doors will need a major shower.

The girls sneakily made their way down the hall. Classes were still in session so they were in the clear.

"I found these in Onii-chan's room. I think they are stink bombs." Kurumi said holding out a few round, green balls. "Let's put it in the lockers!"

"Hai~" Kiyoko followed and the two put the bombs in random student's lockers.

"Ne, I heard Asano Gakushuu is the most popular person here. Let's write love letters~" Kiyoko said giggling.

Kurumi smirked. "That will be fun~"

"How do we tell it's a girl locker?" Kiyoko asked.

Kurumi stared at Kiyoko. "It will be both girls and boys! We need more yaoi!"

"What's yaoi Onee-chan?"

"Boy loving a boy!"

"Oh okay" Kiyoko said.

The two then quickly wrote a few letters and dropped them in student's locker that haven't been planted a bomb with.

The two then ran when the bell rang.

Students quickly ran out of their classrooms in hopes to get to the lunch line first. They dropped their backpacks in the lockers...

"GYAAAA!" was heard from the hallways.

Meanwhile, two little redhead were busy keeping their laughter in.

....

Nagisa and Kayano were walking pass the main building campus. The two went out to get some juice at the vending machine since theirs was broken as usual.
