Rookie manga artist Teppei Sasaki has worked tirelessly to become serialized in the pages of Weekly Shounen Jump only to be rejected again and again. When the latest one-shot he placed all his hopes in is dismissed, Teppei resolves that after four long years, he should just quit. But just as he makes the decision, lightning strikes his apartment, fusing his microwave and fridge together. As he inspects the mess, the microwave miraculously spits out a magazine: an issue of Shounen Jump from 10 years in the future.

Frontlining this issue is a new serialization titled "White Knight" by Itsuki Aino, a debut so flawless that it moves Teppei deeply. When the issue disappears thereafter, Teppei believes that the idea came from his own imagination and quickly works to copy it down as a one-shot. Submitting it to Shounen Jump, the editors are amazed and decide that the work is good enough to run as a series. With his dreams finally realized, Teppei works to refine the one-shot and it debuts soon after. Meanwhile, elsewhere, a 17-year-old Itsuki Aino opens the latest issue of Shounen Jump to find her fledgling story within its pages, a truth that will soon come crashing down upon Teppei.
