For viewers in 2006, this was a game-changer. The "Clock Up" effect became the signature of Kabuto , influencing countless action sequences in media that followed. Most Kamen Rider protagonists are reluctant heroes. Shinji (Ryuki) was a reporter. Takumi (Faiz) was a loner. Tendou Souji is... arrogant.
Fans often cite this moment as the peak of the episode. The "Cast Off" sequence isn't just a visual gimmick; it is a metaphor for the entire show. Tendou discards the unnecessary weight of doubt and fear to reveal his true, unstoppable self. If the Cast Off was the reveal, the Clock Up was the revolution.

Explosive bolts detonate. The heavy outer shell blasts away, ricocheting off the Worm and the walls. What emerges is the sleek, crimson, beetle-eyed .
In the sprawling, multi-decade legacy of the Kamen Rider franchise, few premieres have landed with the same explosive, genre-defining confidence as Kamen Rider Kabuto Episode 1. Airing in January 2006, during the 35th anniversary of the series, this episode—titled "The Greatest Grandfather" (Saikyō no Ojīchan) —didn't just introduce a new hero; it introduced a philosophy . For viewers in 2006, this was a game-changer
The final shot is Tendou pointing to the sky. "Grandmother said this: Walking the path of heaven, the ruler of all. I am the strongest."
Episode 1 wastes no time. We are thrown into a world of paranoia where your neighbor, your boss, or your mother could be a Worm about to molt into a praying-mantis nightmare. The episode opens with a high-octane prologue. A young woman named Hiyori Kusakabe is working at her family’s restaurant, "Bistro la Salle." Suddenly, a stage of Worms attacks the city. ZECT’s elite squad, including the hot-headed Arata Kagami , deploys to fight back. Shinji (Ryuki) was a reporter
The production design of the itself is a standout. It looks like a real insect—a mechanical hercules beetle that skitters across the ground and latches onto the user. It is one of the most iconic transformation trinkets in Rider history. The Cliffhanger: A Promise of Chaos As the episode ends, Tendou and Kagami share a tense stare. ZECT realizes they cannot control this rogue Rider. Hiyori recognizes Tendou as a ghost from her past (connected to the meteorite crash). And a mysterious silver Rider— TheBee —is hinted at in the shadows.
