Sparks of Tomorrow (aka 20 Seiki Denki Mokuroku, 二十世紀電氣目録) looks like a promising animated series where steampunk rules the skies, and thankfully, the setting isn’t another Victorian London retread. Instead, this alternate-history version of Kyoto brims with strange machinery, airships, and the lure of adventure.
Based on the light novel 20 Seiki Denki Mokuroku by Hiro Yūki and illustrated by Kazumi Ikeda, the adaptation already carries a sense of wonder. July isn’t far off for viewers eager to see where Kihachi Sakamoto’s search for his missing brother will lead. With Netflix handling international distribution, audiences both local and abroad will be able to follow the mystery beginning July 5, 2026.
At the centre of the story is a young inventor determined to obtain the mysterious “20th Century Electrical Catalog,” a book said to contain knowledge to deliver a future beyond this world’s steam-powered age. The title alone hints at upheaval.
Once electricity enters the picture, locomotion, communication, and air travel could evolve into something entirely different. Whether figures like Nikola Tesla will be part of the narrative remains unclear, the hints shown in the trailer is not denying the possibilities!
The overall story arc suggests a collision between industry and innovation. The catalog’s connection to the disappearance of Kihachi’s sibling adds another layer of intrigue, while Inako Momokawa’s true motives remain hidden.
With Kyoto Animation producing the series, expectations are naturally high. The studio is best known for K-on and Suzumiya Haruhi no Yuuutsu (2009). Having visited the city years ago, I can already see echoes of its architecture and atmosphere peeking through the promotional material. There’s plenty of room here to explore how tradition collides with technological progress, especially in a story about a boy coming of age while standing at the edge of a rapidly changing future.
Director Minoru Ota leads the production alongside series composer Tatsuhiko Urahata and character designer Kohei Okamura. The voice cast includes Yuma Uchida, Sora Amamiya, Koki Uchiyama, and Daisuke Ono.
