Sparks of Tomorrow Synopsis:
In an alternative version of the early 20th century, where steam power developed rapidly and progress has now stagnated, Kyoto is wrapped in soot, smoke, and steam.
Kihachi Sakamoto, a skeptical boy, is tormented by the loss of his brother, with whom he once dreamed of an “electricity age.” Inako Momokawa, a deeply spiritual girl, is forced to hide both her dreams and her sorrow for her mother’s death.
When Inako crosses on Kihachi’s path, his meeting creates a spark that drives them to challenge a new era, with the electrical catalog of the 20th century as a guide: a mysterious and visionary record full of secrets that could change the world.
To go beyond what they are now and recover the dreams they once had: This is a story of renewal.
