This is just a random storyline I choose while half asleep. We'll just see what becomes of it, I guess.
It was 05:00 when he woke up unexpectedly. He had another hour before he was actually supposed to get up and prepare for school. But something had started to poke and prod his chest. Cracking open a sleepy eye, he noted that it was an annoying and arrogant red brown colored cat. "Get off of me, Karma. Just because I have to babysit you until you're back to you're human form doesn't mean you're allowed to use me as you're personal servant and pillow."
Yes, Karma Akabane, one of Kunugigaoka Junior High School's top E-class students and shape shifters, had gotten stuck in his cat form and was being watched over by Nagisa Shiota. In other words, Karma had screwed up and now had to be babysat by one of his fellow classmates until he was human again.
When shape shifters gain their first form they can shift into, generally at the age of 16, it's extremely easy for them to get stuck in that form if they use it too much within the first week of gaining it. When they get stuck, they shift back to a human naturally about three days later. As shifters get older they gain more forms, but don't get stuck quite so easily.
And wouldn't you know it, the first shifter to get stuck in the E-class happened to be Karma, right at the beginning of his family's reunion, which meant he had no one at his home to take care of him while he was stuck. Thus, his classmates got to decide who would take care of him. As it turns out, most of the class wouldn't be able to, and out of those who could, Nagisa was chosen.
"Remember, you still have to go to school as well." For that comment, Nagisa got a hiss and claws poking him. "Ow! Hey, I'm not the one who makes the rules."
The cat curled up on his chest and showed no intention of moving. Nagisa sighed before attempting to go back to sleep. Unfortunately for him, his attempts failed.
That's the introduction done. I plan to explain more about shape shifters as the story progresses, but that's about all I've planed out, aside from the pairings, of course.
