The television series "Nijuuseiki Denki Mokuroku – Eureka Evrika" (known internationally as "Sparks of Tomorrow"), produced by Kyoto Animation, is entering the home stretch. At the start of the final episodes, a second story visual was released, showing the characters of the story in a noticeably more tense phase.
The image focuses on several motifs: mysterious architectural drawings, a Kihachi Sakamoto absorbed in his work, and Inako Momokawa, whose posture and appearance are reminiscent of her mother Naeko – who once worked as a Tōji, that is, as the head of a sake brewing operation. Also visible are Yōsuke Mizoe, who seems to be plotting something in a hidden basement room while wearing an inscrutable expression, and Seiroku Sakamoto, the character from whom the entire plot originates.
At the same time, the plot of the eleventh episode, titled "Sasou Kairo" (roughly "Inviting Circuit"), was released, which will air on September 13. In it, Inako sneaks into Mizoe's shop together with Saki to track down the "Denki Nishiki" recorded in the "Denki Mokuroku," while Kihachi focuses entirely on deciphering the riddle that reached him from Seiroku. Both go their own way in order to obtain the key to their shared dream. Kihachi intrudes into a forbidden area and is locked in the dark; his risky challenge is meant to bring the true secret of the "Nijuuseiki Denki Mokuroku" to light. The episode is written by screenwriter Tatsuhiko Urahata, with storyboards by Tatsuya Ishihara and Ryō Miyagi, direction by Ryō Miyagi, and animation direction by Mariko Takahashi. A web trailer for the episode was also released.
The series is set in an alternative Kyoto of the early 20th century, in which only the steam engine has prevailed and the city lies under smoke. At the center are the distrustful boy Kihachi, who has lost his brother, and the devout Inako, who hides her dreams and her regret toward her deceased mother. Together they search for the secrets of the "Twentieth Century Electricity Catalog." Kihachi is voiced by Yūma Uchida, Inako by Sora Amamiya; other roles include Kōki Uchiyama, Daisuke Ono, Shunsuke Takeuchi, Minako Kotobuki, Yō Taichi, Natsumi Kawaida, Kazuki Ura, Daisuke Hirakawa, Hiroshi Yanaka, Mayumi Asano, Daichi Endō, and Ayahi Takagaki.
The source material is the novel of the same name by Hiro Yūki, which was published on August 10, 2018 under the KA Esuma Bunko label by Kyoto Animation and was awarded a promotional prize at the eighth Kyoto Animation Award; the illustrations are by Kazumi Ikeda, backgrounds and scene design by Momoka Nagatani. An anime adaptation had already been announced in 2018, but its status remained unclear for a long time after the arson attack on the main studio in 2019. Only on October 25, 2025, during the event "KyoAni no Sekai-ten," was it announced that it would be a television series. Direction is by Minoru Ōta, series composition by Tatsuhiko Urahata, character design by Kōhei Okamura, world design by Takaaki Suzuki, and music by Hitomi Koto. The opening theme "Eureka Evrika" is by Luna Goami, and the ending theme "Soarin'" is by Ginger Root.
