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

A youth novel about a science university student by the author of "Yokohama Station SF" and "Stories of Humans."

The Earth has expanded due to the excessive mining of "Juso" (gravity elements), which govern gravity. It is the year 2013, and the distance between Tokyo and Osaka has exceeded 5,000 kilometers. Wataru Yukawa, who enrolled in the Department of Juso Engineering at the Faculty of Science and Technology, encounters a book at the secondhand bookstore where he works part-time. "Airplane Theory" - a technology envisioned 100 years ago but forgotten without ever being realized, a way to fly in the sky without using Juso. "I'm going to build an airplane, the first in the world." The days of reckless challenges by an ordinary science student have begun.

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