Johan Anderson, a high school teenager in Japan, along with his classmates, is suddenly summoned to another world by an empire that needs a hero to win the war. Each student gets a job that determines their abilities, but Johan gets a job that seems strange and useless: 'Modern Soldier'.
Johan sat in the cockpit of the fighter jet, feeling every vibration of the engine and the roar of the wind against the aircraft's hull. His strong hands gripped the control stick firmly, his gaze piercing through the cockpit glass, staring at the palace below, which now seemed like a miniature amidst the vast night. The jet sped swiftly, soaring over the majestic palace towers, leaving everyone below in stunned silence. In this world, the technology to fly was far beyond the imagination of its inhabitants, making the fighter jet appear like a giant iron bird from legend descending upon the earth.
