On that day, the fog blocked everything.

On that day, he became the captain of a ghost ship.

On that day, he stepped through the thick fog and confronted a completely subverted and fragmented world—the old order had vanished, strange phenomonoms dominated the endless seas beyond civilized society, and isolated island city-states and fleets of ships challenged the sea that had become the last ember of lights for the civilized world.

Intellectual Villages are old fashioned rural villages recreated with cutting edge technology. Those villages attract the Japanese monsters known as Youkai.

The high school boy Jinnai Shinobu lives in one of those villages and has a Zashiki Warashi living in his house. He tends to run across Youkai with unnerving frequency and this often leads to trouble for him.

“Hey, have you ever heard of the lunatic roaming around the tower?”“Are you kidding me? Who haven't heard of him yet!?”“Hey hey, are you talking about... that person?”Interesting news travels even faster than light, especially regarding the mysterious figure that everyone in the Ethereal Tower is curious about, the lunatic ascender whom thoughts and deeds are so off-place that even the greatest among them just couldn't grasp his intent, almost as if he is ascending a completely different tower than them.While everyone in the tower talks about the lunatic who lurks on each tower's floor more than he is supposed to, the person they are talking about just goes on his merry way to collecting treasures he wants, and while the world is talking about him.“Come on, give me some luck, maybe roll the hundred times multiplier again...”He's sitting while rubbing his palm together, gambling on something that will make everyone faint.

On the surface, he is the aloof and standoffish patriot whose sole purpose is to serve the nation. On the darker side, he is an invincible, powerful and mysterious man.
