Kamen Rider Zero-One: Review: End of the Beginning

April 26, 2026

Episode 15, “End of the Beginning,” serves as the explosive first-act finale, delivering a heavy dose of consequences for both Hiden Intelligence and MetsubouJinrai.net. The episode is defined by its relentless pace, as Aruto and Fuwa launch a direct assault on the terrorist base at Daybreak Town. The debut of Shining Assault Hopper is a visual treat, merging the tactical precision of the Shining Key with the raw power of the Assault Grip. Watching Aruto utilize the “Shining System”—a swarm of funnel-like projectiles—shows a significant evolution in his combat style, proving he can finally stand on equal footing with the most dangerous threats.

The narrative climax centers on the downfall of Horobi and Jin, providing a rare moment of vulnerability for the villains. Horobi’s “sacrifice” to protect Jin from a finishing blow is a fascinating development; it hints that even a Humagear dedicated to the Ark can experience something akin to parental instinct, further blurring the line between programming and soul. However, the victory feels bittersweet. While the immediate threat of the Magia is quelled, the physical and emotional exhaustion of the cast is palpable, and the destruction of Jin by the episode’s end marks a definitive, tragic close to the series’ first major chapter.

Overall, this episode succeeds because it doesn’t just offer an ending; it pivots the entire series toward a new, more corporate threat. The introduction of the Thouser Driver in the final moments, coupled with Gai Amatsu’s hostile takeover bid for Hiden Intelligence, shifts the conflict from the battlefield to the boardroom. It’s a transition that feels earned, moving away from the “monster of the week” format into a high-stakes war for the company’s future. Episode 15 effectively closes the book on the Ark’s first awakening while making it clear that the true battle for Humagear rights is only just beginning.
