A Military Otaku is Reincarnated Into a Magical World, Building a Military Harem Using Modern Weaponry!?

Lute, a boy reincarnated into a magical otherworld, will use modern weapons to create a legend!

Lute—a boy who died after being caught up in a case, only to wake up to find himself reborn in a magical world.

In a world where magical talent can dictate one's life, his magical power is pitifully small.

So he used modern knowledge to create "guns"—he was a "military geek" who loved military equipment during his "life"!

Harboring the unfulfilled desire to save others from his past life, Ryuto works hard to create weapons to protect his childhood friend, the dog-eared girl Shirayuki, from the approaching monsters!

This is the story of a boy who eventually creates his own army (harem) and uses that power to save people—a story that may soon become a legend!
