宇宙船をもらった男、もらったのは星だった！？

I’m a man in my early thirties who was forced to resign from my company after being falsely accused of inspection fraud. Somehow, I found myself recruited as the captain of a spaceship. And not just any spaceship – this one was a colossal vessel, larger than Earth itself.

This is the story of Keiichi Yamada, who suddenly becomes the captain of an enormous spaceship. He negotiates with the Japanese government, enjoys moments of leisurely living, and saves the universe from crises. The catchy tagline refers to an episode that occurs much later in the story.
