Despite multiple rejections, up-and-coming manga artist Teppei Sasaki perseveres in his quest to be published in Weekly Shounen Jump. After a devastating dismissal of his latest one-shot, Teppei is ready to throw in the towel, but a freak accident changes his fate. A lightning strike fuses his microwave and refrigerator together, causing a magazine to mysteriously appear. It turns out to be an issue from a decade in the future, featuring the flawless debut serialization "White Knight" by Itsuki Aino. Inspired, Teppei creates a one-shot based on the idea before realizing it wasn't his own imagination. His submission wows the editors, who decide to run it as a series, making Teppei's dream a reality. However, unbeknownst to him, the actual Itsuki Aino is a 17-year-old whose fledgling story has also been published in the latest issue of Shounen Jump. The truth is bound to come out and wreak havoc on Teppei's new-found success.
