二十世紀電氣目録-ユーレカ・エヴリカ-

In the summer of 1907, Inako Momokawa, second daughter of a Fushimi sake brewer, can do nothing right in her father's eyes and takes her troubles to the gods at the Fushimi Inari shrine in Kyoto. There she meets Kihachi Sakamoto, a freewheeling young man who scorns the gods and preaches a coming age of electricity. When her father arranges a marriage for her without asking, the two set out across Kyoto and Shiga to find the Electricity Catalog, a book of predictions Kihachi wrote as a child that his older brother Seiroku carried off. Based on the light novel.
