Yuiga Nariyuki works hard every day to obtain a full-college scholarship by his High School to support his poor family. His headmaster promises that he'll get it if he full-fills a small condition. He has to tutor two resident female geniuses Furuhashi Fumino (Literature-genius) and her friend Ogata Rizu (Science-genius), so that they can get into their dream-college. The catch is that Fumino wants to major in Science and Rizu wants to major in Literature despite them failing constantly in those subjects.

Their city is filled with criminals and three incredible high schoolers. Yugo, Rikiya and Tasuku are determined to clean up the city with whatever means necessary, even if that means using violence.

During a typical night of wiping out gangs, Tasuku comes across a beautiful girl held prisoner. She helps him survive what would have been a mortal wound by allowing him to see the future. Tasuku takes her home where he finds that her name is Noah, she doesn't speak at all, and has no memory. Even more fascinating to Tasuku, she bears the same tattoo as the person he has been searching for years for.

Spiin-off series based on Komi Naoshi series Nisekoi.
