Karma's sister goes to the festival~ (Assassination Classroom fanfic) (AU)

Class E's time at the festival

It was a warm summer's eve as the town's local festival started. The guys had all made plans with their girlfriends to meet up there, but before that could happen the girls said they needed to grab a few things and didn't allow the boys to see them before the festival. Kiyoko was hopping up and down in excitement, but upon hearing Karma sigh she stopped.

"What's wrong Onii-chan?" Kiyoko asked.

"Well Kiyoko, you see I kind of have plans with the class, so I can't take you" Karma said rubbing the back of his head.

"Oh I see" Kiyoko said dejected.

"But hey maybe tomorrow okay," Karma said ruffling her hair "But for tonight it will just be us okay?"

"Okay" Kiyoko said softly.

In the Akabane Household, Kiyoko was feeling bored and her mother was downstairs washing dishes.
"Ah, it's boring without Onii-chan or his classmates...I wanted to go to the festival too..." She rolled over on her bed in boredom.
"Maybe I'll play Onii-chan's 3DS..." Kiyoko thought as she dragged herself out of bed and into Karma's bedroom. She found the game system on his desk and started playing it as she walked towards Karma's bed. She was still playing the game in boredom on the bed before she heard a knock on the window.
Surprise, surprise...
"Hi Octopus-sensei!" said Kiyoko as she shut off the game system. The girl was happy to have someone to play with. "Ne ne, let's play!" she said excitedly.
"Nufufufu, good evening Kiyoko-chan. You were left behind too?" he asked stepping into the room.
"Eh, they didn't take you too?" asked Kiyoko.
"No" the octopus cried. "I wanted to take pictures of them and have some juicy gossip! I also need to earn some extra money to buy snacks. I ran out of money and it is still a long way to go if I wait for payday..." Koro-sensei said. "So I'm going to the festival with the excuse of earning money."
"Take me with you!" Kiyoko pleaded. "I'm booored. Onii-chan said he'll take me tomorrow, just the two of us, but that's a long time" whined Kiyoko. "I can take the pictures while you make money! Onii-chan taught me how to take good pictures. Both for normal and blackmail! Can I go with you Octopus-sensei?"
Koro-sensei looked stunned. Wow, Kiyoko was really taking after Karma. The teacher is going to be blackmailed by his own pupil. "Sure you can! Let's hurry!" said an excited Koro-sensei.
"I'm going to get my yukata. That way it will be easier to hide."
Koro-senei nodded his head in approval.
"Ah, I'm also going to tell Okaa-san I'm going to bed early."
"Hai hai"
Kiyoko went downstairs. "Okaa-san~ I'm going to bed early since Onii-chan left me!" she said to the red-haired woman.
"Oh Kiyoko-chan, your brother is on his date. He needs to spend some time with his girlfriend too. -sigh- alright then. Sleep tight alright" the woman said as she kissed the pouting girl's forehead.
"Good night." Kiyoko then walked up the stairs and her mother never saw her daughter smirking.
Kiyoko went to grab her blue yukata that also had white rabbits in the fabric. She also grabbed the white sash that went along with it and went towards Karma's room where Koro-sensei is.
"I'm back~" she said holding the yukata.
Koro-sensei quickly changed her and did her hair in a simple low, sideway ponytail with a rabbit pin.
"Yatta! Can't wait. Do I also get to play?" she asked.
"Hai! Here is a camera!" he said as he put a camera around her neck. "Now you can take blackmail pictures if you wish, and also take lovey dovey pictures too!"
"Yay~" Koro-sensei lifted Kiyoko and they both headed towards the festival.
The couples better watch out. They are going to be spied on by Karma's little sister/pupil.

"Wow, she must have sounded like a kicked puppy" Nagisa said as he and Karma met up with Sugino

"She did, I don't know man" Karma sighed slicking his hair back.

"So you guys excited" Sugino asked "I bet the girls will look classy in their yukatas"

"I hope so, I always wonder what Okuda and Kaede would like in Yukatas" Nagisa said
