Tendou ignores this warning. When the Worm uses a human shield, Kabuto hesitates... and then uses a kick that phases through the human to destroy the Worm. This moment showcases the genius of the writing: Tendou rejects the system's cruelty, establishing his moral code without a single line of sentimental dialogue. Rewatching Kamen Rider Kabuto Episode 1 today, the use of practical effects is astonishing. The "Cast Off" sequence—where the heavy armored parts literally explode off the suit—was done with actual air mortars in the costume. This gives the transformation a tactile, mechanical weight that modern CGI transformations sometimes lack.
Press play. Cast off. And walk the path of heaven. Lost half a point only because we have to wait until Episode 2 to see his "Rider Kick" in full glory. kamen rider kabuto episode 1
"Walking the path of Heaven, the one who will rule over everything." Tendou ignores this warning
If you are a newcomer looking to get into the series, or a veteran wanting to revisit the origin of the ZECT War, this deep dive into Episode 1 will explain why this 2006 premiere remains a landmark in Tokusatsu history. The episode opens with a flashback that sets the entire mythology in motion. Seven years before the main plot, a massive object—later identified as the meteor carrying the alien Worms—crashed into Shibuya, Tokyo. The impact was catastrophic, leveling the city and causing a timeline split for the survivors. From this wreckage emerged the Worms: shape-shifting insects capable of mimicking human beings perfectly, down to their memories and emotions. This moment showcases the genius of the writing:
From his first appearance, Tendou is in complete control. He runs a small but immaculate restaurant with his sister, Hiyori. When he isn't cooking the perfect Japanese curry, he is mastering martial arts. The episode establishes his "God-like" complex not through boasting, but through action.
In the climax of the episode, a Worm reveals itself and activates Clock Up. From the civilian perspective, he has vanished. The episode brilliantly captures the terror of this power—police officers are thrown around by an invisible force.
The battle shifts from a horror film to a high-speed ballet. The Episode 1 climax features groundbreaking CGI for 2006, showing Kabuto and the Worm fighting in fractions of a second, while rain hangs frozen in the air like diamonds. It is a visual feast that makes the title sequence feel earned. While the action is flashy, Episode 1 plants a dark seed. The ZECT advisor, Riku Kagami (father of the secondary protagonist), reveals the secret of the "Red Shoes System." This is an automatic programming inside the Kabuto suit. If a Worm mimics a human, the Red Shoes will force the Rider to kill the host along with the Worm—human sacrifice be damned.
