This early masterpiece novel, originally published in 2017 by the currently most-watched SF author Yuba Isukari, is finally receiving its long-awaited paperback release.

Life is an airplane. If you move forward, you can fly.

A youth novel about a science student, written by the author of 'Yokohama Station SF' and 'Tales of Humans.'

The year is 2013. The Earth has expanded due to the over-extraction of "gravitons," the elements that govern gravity, and the distance between Tokyo and Osaka has exceeded 5,000 kilometers. Wataru Yukawa, a freshman in the Department of Graviton Engineering, discovers a book at the used bookstore where he works part-time: 'Airplane Theory.' It describes a technology for flying without the use of gravitons—a concept conceived 100 years ago, but never realized and since forgotten. The days of reckless challenges for this ordinary science student, who decides to become the first person in the world to build an airplane, have begun.

Fly, to the distance! In humanity's first "airplane"! An exhilarating youth graffiti.
