The Demon Lord's Army, engaged in a relentless war against the Human Army, found itself on the verge of collapse.

With iron dragons soaring through the skies, iron horses dominating the land, and a rain of steel unleashed from beyond the horizon, the Human Army's mechanical weaponry pushed the Demon Lord's Army to a desperate measure: an attempt to summon a savior from another world, hoping for a complete reversal.

This would surely save the Demon Lord's Army—

"Um, I can only do office work, though."

"Wait."

—Or so they thought, but that wasn't the case.

I, Akitsu Akira, living a perfectly ordinary life in modern Japan, was suddenly hit by a truck, sent flying, and then transported to another world, immediately faced with the impossible task of "saving the Demon Lord's Army." My protest—"How can *I*, who can only do office work, possibly do that?!"—was met with the unreasonable retort, "It would be a waste!", and I found myself assigned to the Demon Lord's Army's administrative department.

Since it seemed I couldn't go home, I figured I'd try my hand at logistics, as befits an army! Or so I thought…

"…What *is* logistics?"

"Excuse me?"

This is the story of how the Demon Lord's Army, once nothing more than a pre-modern fighting force, transformed itself by leveraging paper, pen, and ink—

"For now, just sign this—"

"I can't write."

"Oh, come on…"

—Or so I wish.
