Teppei Sasaki wants to be a mangaka at Weekly Shonen Jump but all his drafts get rejected by his editor for being too boring. One day, lightning strikes his house and an issue of WSJ from 10 years in the future pops out of his microwave! He is highly impressed by a debuting series called White Knight by Itsuki Aino.
Believing this was just a hallucination and that the story was of his own making, Teppei presents it to be published and it gets accepted! However, when the story is published, WSJ superfan Itsuki Aino recognizes her own character being written by another author and becomes angry at this theft of her work, unaware it is her own story from the future!
