In a certain world, on a certain planet,

Lived certain beings.

Beings who innovated, invented, and discovered

Beings who worked, persevered, and eventually dominated.

Yet, they were weak.

Of their physical abilities, they were merely average.

They had no unique abilities, unlike the other creatures of their world.

....

No.

Perhaps that wasn't true.

They had knowledge.

Knowledge, a power that no other had mastered.

This race used that knowledge to hunt, to build, and to eventually become powerful enough to rule their little planet.

Yes. They were humans.

Mostly hairless creatures, with weak bodies and able minds.

With the power of knowledge, they created the glory of man.

And this is a story about one of those humans, an unfortunate young man named Kurumi Touya, who chanced upon fortune that changed his life forever.
