The 13-episode story centers on their pursuit of electricity through the rediscovered 20th Century Electrical Catalog, incorporating romantic tension, family secrets, inventions, and a final clash with antagonist Yosuke Mizoe. Core themes of innovation, brotherly bonds, romance, and personal growth drive the narrative without activist framing, identity lectures, or critiques of traditional norms, as confirmed by episode synopses that rely on classic tropes such as elopement, music battles, reconciliation, and chasing an unseen future light. Creator statements emphasize yin-yang character dynamics, themes of regeneration, and technological hope rather than social messaging, while isolated critic complaints about the villain's portrayal remain disconnected from any embedded progressive content.

Casting choices preserve historical and cultural fit with no race or gender swaps of established figures, and audience reception signals show no meaningful critic-audience divide tied to ideology. The result is a premise where entertainment elements stand on their own without political overlay.
