There were boys who dreamed of an “Age of Electricity.”
The protagonist, Kihachi Sakamoto, fills out a notebook called the “20th Century Electrical Catalog” with his ideas for future electrical inventions. Together with his admired older brother, Seiroku Sakamoto, he vows to make those dreams a reality.
But Seiroku takes the 20th Century Electrical Catalog with him to war and never returns.
Years pass. Through a chance encounter with Inako Momokawa, the daughter of a sake-brewing family, the 20th Century Electrical Catalog—which was thought to have been lost forever—reappears before Kihachi.
Also seeking the catalog is Yosuke Mitsuzoe, the heir to a powerful steam-industry conglomerate who is pursuing a political marriage with Inako.
As Kihachi and Inako stand against Yosuke, they embark on a bold electrical challenge, staking their dreams on the future of technology.
Why is Yosuke so obsessed with obtaining the 20th Century Electrical Catalog?
And what is the “secret” of the catalog known only to Yosuke and Seiroku?
As the 20th Century Electrical Catalog becomes the center of a struggle, the dreams of these young men and women begin to move once more.
This is a story of rebirth.
