The core premise follows Kihachi Sakamoto, a cynical young inventor mourning his lost brother Seiroku, and Inako Momokawa, a sake brewer's daughter who prays at Fushimi Inari shrine, as they recover the 20th Century Electrical Catalog and pursue inventions together amid rival Yosuke Mizoe's steam interests. Episode plots center on building electric machines, a music battle with electric instruments, proving passion through experiments, and personal growth through ingenuity and family legacy—classic coming-of-age and innovation storytelling with no activist framing.

The alternate-history premise centers technological dreams and personal rivalry in a Meiji-era Kyoto setting, keeping thematic focus on invention, family trauma, faith, and romance rather than any ideological messaging. All-Japanese cast and voice actors align with the historical Japanese context, and the series contains zero creator statements or plot elements involving DEI, gender ideology, or social justice messaging. Traditional character arcs around family trauma, faith, romance, and invention remain free of identity politics or systemic critiques, resulting in entertainment that prioritizes mechanical creativity and emotional growth over contemporary political themes.
