Early 20th-century Kyoto. Kihachi witnesses the wonders of electricity with Seiroku. Four years later, alone and cynical, he meets a girl deep in prayer.

In a haze of incense, Yosuke storms into Kihachi's workshop and demands the Catalog — and his fiancée. But why does Inako have it in the first place?

Full of denial, Yosuke clashes with Kihachi. Later, Inako's sharp senses reveal a secret and her belief inspires Kihachi to recreate an invention.

Inako meets a grieving shop owner whose loss echoes her own. Fully believing in Kihachi's skills, she asks him to build an electric machine to help.

Kihachi's latest experiment catches the eye of a strange university graduate, who's convinced that it can help him prove his passion to his crush.
