In a world where the Earth is expanding and anti-gravity devices exist, science student Wataru Yukawa recklessly attempts to build humanity's first "airplane." This early masterpiece novel by Yuba Isukari, one of today's most talked-about SF authors, originally published in 2017, is finally being released in paperback. The paperback edition of 'Gravity Alchemy,' with a newly revised afterword, will be released by Shinchosha Bunko Nex on March 30, 2026.

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

A coming-of-age novel about a science student by the author of 'Yokohama Station SF' and 'Ningen-tachi no Hanashi'.

The Earth has expanded due to the over-extraction of "gravity elements" that control gravity. The year is 2013, and the distance between Tokyo and Osaka has surpassed 5000 kilometers. Wataru Yukawa, who enrolled in the Department of Gravity Element Engineering at the Faculty of Science and Technology, encounters a book at the used bookstore where he works part-time: 'The Theory of Flight'—a technology for flying without using gravity elements, conceived 100 years ago but forgotten due to its unfeasibility. Thus began the days of reckless challenges by an ordinary science student: "I think I'll build an airplane, the world's first.".

Fly, far away! With humanity's first "airplane"! An exhilarating youth graffiti.
