The Worms are defined by duality: human and monster, victim and impostor. This theme extends to the Kamen Rider system itself, which has two forms— and Rider Form —accessed through "Cast Off."
The episode lives and dies by its introduction of Tendou Souji. Within minutes, we learn everything we need to know about him: he is arrogant, hyper-competent, and walks to the beat of his own drum. The "Grandmother used to say..." catchphrase could have been annoying, but actor Hiro Mizushima delivers these lines with such unshakeable confidence that it immediately becomes iconic. He isn’t a struggling everyman like many Riders before him; he is a "Chosen One" figure who knows he is the best. It is a refreshing dynamic that sets the show apart immediately.
If you’re waiting for a sign to start your journey, remember that Tendou didn't wait for the ZECTer to find him; he walked into the fire and made it his. kamen rider kabuto episode 1
Just as the situation turns fatal, a high-tech armored transport vehicle arrives, deploying the —a sentient, mechanical rhinoceros beetle. The ZECTer is designed to bond with a chosen operator to form the ultimate anti-Worm weapon. Kagami, believing his desire to protect people makes him the chosen one, reaches out for it.
From the meteor’s surface, hundreds of shimmering, insect-like shadows detach and scatter into the city. They move faster than the eye can follow. People freeze, then vanish—not killed, but taken .

Kamen Rider Kabuto (2006) premiered with an episode that redefined the tone of the Heisei Rider era, presenting a protagonist who was not just heroic, but undeniably, almost arrogantly, perfect. Episode 1, titled "The Strongest Man" (最強の男, Saikyō no Otoko ), is a masterclass in establishing a unique, charismatic lead while setting up a stylish, fast-paced sci-fi narrative.
Episode 1 of Kamen Rider Kabuto succeeded because it balanced style with substance. It delivered Hollywood-adjacent special effects, an intriguing sci-fi mystery, and a protagonist whose sheer charisma carried the entire production. By refusing to give the power to the traditional underdog, the episode challenged the audience's expectations of what a superhero show could be. The "Grandmother used to say
The high-energy opening theme, "NEXT LEVEL" by YU-KI (of the famed J-Pop group TRF), perfectly encapsulates the series' tone. Its driving digital beat and soaring vocals, which speak of a "chosen one's" wishes becoming reality, mirror Tendou's unshakeable belief in his own destiny. The song's popularity even extended beyond the show's target audience, becoming a hit with housewives due to the show's handsome cast.
The debut of Kamen Rider Kabuto is a spectacle. The "Cast Off" sequence (shedding the bulky armor to reveal the sleek Rider form) is a genius toy gimmick that translates perfectly to screen. The sound design, the voice calling out "Change Beetle," and the sheer speed of the Rider form make for an exhilarating climax.
Traditionally, the main Kamen Rider is an everyday hero who stumbles into power. Episode 1 tricks the audience into thinking Arata Kagami is that protagonist. Kagami is an apprentice member of ZECT, a secret organization dedicated to fighting the Worms. He is passionate, clumsy, intensely moral, and desperate to protect people. He views himself as the chosen savior, making his journey relatable and deeply human. Souji Tendo: The Man Who Walks the Path of Heaven
