Recap: What Happened Before Episode 9

The story of Sparks of Tomorrow is set in an alternate version of the Meiji era where steam engines are the main source of power. The show revolves around the “20th Century Electrical Catalog,” a book that holds the key to bringing electricity to the world.

The main character, Kihachi Sakamoto (voiced by Yuma Uchida), once dreamed of the “Age of Electricity” with his older brother, Seiroku Sakamoto (voiced by Daisuke Ono). However, Seiroku took the catalog to war and never returned, leaving Kihachi alone and cynical.

Years later, Kihachi meets Inako Momokawa (voiced by Sora Amamiya), the daughter of a sake brewer. Inako is pressured by her family to accept an arranged marriage. She wants to escape her fate, and Kihachi offers her a way out. The only way to stop her marriage is to find the lost Electrical Catalog.

The early episodes showed Kihachi and Inako forming an unlikely team. Episode 3 saw Yosuke Mizoe (voiced by Koki Uchiyama), who is Inako’s fiancé, clashing with Kihachi. Inako’s sharp senses helped reveal a secret that inspired Kihachi to recreate an invention. Episode 4 had Inako meeting a grieving shop owner and asking Kihachi to build an electric machine to help her. Episode 5 introduced a strange university graduate who was interested in Kihachi’s experiments.

As the story progressed, the search for the catalog became more intense. Kihachi finally got his hands on the book, but Yosuke reached him before he could examine it. The tension between Kihachi and Yosuke has been growing, especially since Yosuke is not only after the catalog but is also engaged to Inako.

What to Expect in Episode 9: “Time of Farewell”

Episode 9 is titled “Time of Farewell” (別れの時). The previews and summaries for this episode show that a major turning point is coming. The episode will focus on a big event: the engagement party for Yosuke Mizoe and Inako Momokawa.

The party is being held on a boat called the Mitsuzoe boat on Lake Biwa. Inako has made a difficult decision. To protect the Electrical Catalog, which is Kihachi’s dream, she has decided to accept the engagement. She goes to the party without telling Kihachi about her plan.

However, when Kihachi finds out what Inako is doing, he takes action. He urges her to chase her own dreams and helps her escape from the engagement ceremony. This suggests that episode 9 will be a major turning point for Inako’s character. She is moving from being a passive participant in her own life to actively choosing her own path.

The episode is also expected to advance the main plot. After escaping, Kihachi and Inako are guided by a letter from a character named Stuart and head toward Shiga Prefecture. This sets the stage for the next phase of their journey to find the Electrical Catalog.
