Joseph Jetson, or Jet as he prefers to be called, has Pyrophobia due to a tragic accident that took his mother's life. Now, he has to juggle a job, school, being an older brother, and a good son. One day, after getting dragged into a problem he'd rather not deal with, he runs into Natsuki Nakamura, a half Japanese, half American girl who refuses to leave Jet alone. Will he ever be able to have peace again? Or, just maybe, will this nuisance of a girl help break down his walls?
