Story Overview

The story takes place in an alternate version of Kyoto during the early twentieth century, in an era where steam technology has flourished, but electricity has yet to transform society.

The city is covered in smoke from steam-powered machinery, creating a fascinating blend of historical atmosphere and speculative technology.

The story follows Kihachi Sakamoto, a young boy who loses both his beloved brother and the mysterious “20th Century Electric Catalog,” a book containing revolutionary electrical inventions capable of changing the future.

After years of living without hope, Kihachi’s life changes forever when he meets Inako Momokawa, the daughter of a sake brewer whose own dreams and personal regrets push her toward an uncertain future.

Together, the two become entangled in a dangerous adventure involving powerful organizations, long-lost inventions, and the possibility of ushering in a new technological era.

Believing his dream to be over, Kihachi lives aimlessly until a chance meeting with Inako Momokawa reignites his determination.

Meanwhile, Yosuke Mitsuzoe, the ambitious heir to a powerful steam industry conglomerate, is searching for the missing Electric Catalog.
