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

Christmas Special

Kiyoko woke up with a smile. She got up from her warm bed and took a bag from under the bed.
It's Christmas which means two things...Christmas and Karma's birthday.
The energetic girl ran out the room and barged in Karma's room.
"Onii-chan! Happy birthday!" She cried out as she dropped the gift by the door and hurled herself to his bed. "And Merry Christmas!"
...
Karma was peacefully sleeping until he herd of Buffalos running and then a slam.
He woke up to find his sister running at him full speed while yelling.
Ain't no one got time for this.
During her jump, he immediately plucked her from the air and wrapped her in his blanket. He then set the burrito Kiyoko and placed her next to him.
"It's too early..." He groaned out as he felt Kiyoko struggle under his grasp.
"Nooooo~"
"Kiyoko, it's..." Karma peered at his clock by his bed, "7:16"
"Yeah. Happy birthday Onii-chan!" Kiyoko said facing him from the blankets. "You're old!" She laughed.
"That last comment was not needed." He deadpanned. "You're staying in that burrito."
"Boo!"
"Back to sleep. Kids are great heaters..." Karma commented as he yawned.
"Onii-chaaaaaan" The burrito girl whined. She knew it was hopeless to escape from the blanket. "Open your present from me..."
Karma groaned knowing she would keeping asking him to open her present. "Fine..." He unraveled (sings Tokyo Ghoul OP) her and the child bolted from the bed.
"Open it!" She chanted as she handed him the bag.
Karma opened it and pulled out a plastic container holding...chocolate cake with two strawberries on top and a (weird) snowman with a balloon.
"Hara-nee helped me bake it and she made the fondent thingie while I created the snowman and balloon! A strawberry for your birthday and one for Christmas!" Kiyoko happily explained while clapping. "Octopus-sensei delivered it so you won't see it! Happy birthday! Merry Christmas!"
Karma smiled and ruffled her hair, "Thanks."
Kiyoko glowed under the appreciation.
"Your present is at the bottom of your dirty clothes bin."
Kiyoko was gone like the wind to find her present.
Karma chuckled and placed his cake on the table by his bed. He then let himself collapse and enjoy the next few minutes of sleep.
He softly smiled as he heard his sister's yells of happiness as she yelled out thank you for her Madoka Magica cosplay of...well Madoka!
Extras~
Karma was sleeping happily, enjoying the blissful sleep until he heard his sister yelling again.
"Onii-chan! Octopus-sensei is in my room!!"
What. The. Heck.
He got up to see what the Hell his teacher wants.
"He's Santa! He brought presents from Class E! He's also going to deliver our presents!"
Well that explains it.
He opened the door to find his teacher dressed as Santa Claus. Kiyoko was giving him her presents (drawings) for him to deliver!
"Merry Christmas Karma-kun! And happy birthday!" Korosensei said as he handed presents to him from himself and the class.
Karma silently took it and Kiyoko's presents from the class was on top of her bed. That huge one must be from the Bitch.
"Well I'm off to deliver!! Good bye~" and he was out the window.
Karma glanced at his sister who opening the huge present. "What do you want to eat?"
"Pancakes as a snowman!" She requested as she pulled out a huge white rabbit beanie bag the size of her whole body.
"Sure thing." He then went downstairs to begin making breakfast.
And that's how the Akabanes spend their Christmas this year!
Merry Christmas and Happy Holidays!!
