The world reels as a mysterious structure appears above Tokyo Bay.

Over ten kilometers long, it was, unbelievably, a mysterious dungeon that brought all sorts of benefits to Japanese territory with each successful clear.

Its effects were varied; for instance, natural resources would gush forth across various parts of Japan's territory each time an area boss was defeated.

"Huh, me…?"

"Yes, you. You're pretty good with the internet, aren't you? We need you to handle the live stream for PR."

"R-right…"

As a member of the first survey team, humble otaku Ground Self-Defense Force officer Shinkai Tooru was live-streamed to the entire world, and as circumstances would have it, he achieved immense results, making the dungeon's effects known globally.

During that stream, due to a blunder by the refined female officer in charge of the broadcast, Tooru's name, which was meant to be kept secret, was revealed… and he ended up being hailed as Japan's strongest hero.

Thanks to Tooru's achievements, the Japanese economy made a V-shaped recovery with an astonishing GDP growth rate exceeding 62%.

Furthermore, the Self-Defense Force gained real combat experience in the dungeons, and Japan began to emerge as the leader of Asia in both economic and military spheres.

※Structured to be thoroughly enjoyable even if you're not familiar with military concepts.
