Kamen Rider Kabuto Episode 1 May 2026

The transformation sequence in Kamen Rider Kabuto Episode 1 is legendary. Unlike the sleek, instant morphs of other series, Kabuto’s transformation has two stages.

First, Tendou is encased in a bulky, insectoid armor called the Masked Form. It is slow, heavy, and seemingly impractical. The Worm laughs, assuming victory. Then, Tendou does the unthinkable. He hits a button on his belt.

"Cast Off!" the suit screams in a booming, digital voice.

Explosive bolts detonate. The heavy outer shell blasts away, ricocheting off the Worm and the walls. What emerges is the sleek, crimson, beetle-eyed Rider Form.

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.

Most Kamen Rider protagonists are reluctant heroes. Shinji (Ryuki) was a reporter. Takumi (Faiz) was a loner. Tendou Souji is... arrogant.

From Episode 1, Tendou speaks in absolute truths. He claims his grandmother told him everything about the Worms and the Riders before she died. He declares that he is destined to save the world. He never doubts, never hesitates, and never apologizes.

This makes Kamen Rider Kabuto Episode 1 fascinating. You aren't sure if you like Tendou, but you can't look away. He is a force of nature. The episode subverts the hero's journey by starting with the hero already at the finish line. He has the power, the confidence, and the mandate. The mystery isn't "Will he win?"—it's "Who is he, really?"

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. kamen rider kabuto episode 1

Kagami is the episode's emotional anchor. Unlike the ultra-confident protagonist we’re about to meet, Kagami is desperate. He wants to be a Rider. He believes his brother was killed by Worms, and he is determined to prove himself worthy of the Kabuto Zecter—a robotic, horned beetle device that is the key to becoming Kamen Rider Kabuto.

During the chaos, Kagami’s team is slaughtered. He is saved by a mysterious, stoic young chef: Tendou Souji. Tendou watches the sky, mutters something about a prophecy, and retrieves a lost pendant belonging to Hiyori.

The turning point arrives at the ZECT headquarters. As a Worm impersonates a high-ranking official, Kagami manages to steal the Kabuto Zecter. But when he tries to activate it, the device rejects him. It flies out of his hands, shattering a window, and lands directly in the grasp of Tendou Souji, who has somehow walked into the most secure facility on Earth without breaking a sweat.

With the Worm closing in on Kagami, Tendou calmly places the Zecter on his waist. A holographic belt materializes. He whispers the iconic phrase: "Henshin." (Transform.)

A mysterious alien lifeform known as the Worms — creatures that can mimic humans perfectly and move at incredible speeds — have been infiltrating society. To fight them, the secret organization ZECT has developed the Masked Rider System, using the Zecters captured from the meteorite.

A new Worm appears in Tokyo, attacking civilians. ZECT dispatches its agents, including Arata Kagami, a young man desperate to become a Kamen Rider. He attempts to use TheBee Zecter, but it refuses to accept him.

Meanwhile, a cocky but skilled young chef named Souji Tendou (now grown) lives with his younger sister, Juka. He hears the commotion and heads toward the battle. Kagami, believing he can still activate a Zecter, reaches for the Kabuto Zecter — but it flies past him and into Tendou's hand.

Tendou calmly says:

"I will rule over everything."

He raises the Zecter, slides it onto the Kabuto Belt (which appeared from nowhere on his waist), and transforms into Kamen Rider Kabuto.

Tendou returns to the restaurant where Hiyori works. He orders his signature coffee (extremely particular about how it’s made). As Hiyori serves him, she notices he is eating alone — at a table set for two.

He quietly says:

"I was waiting for my sister... but she never came."

The implication: His sister was lost in the Worm attack 7 years ago (or was taken by ZECT?).

The episode ends with a shot of Tendou looking up at the sky, repeating his grandmother’s words:

"Walk the path of Heaven, the road that rules over all." The transformation sequence in Kamen Rider Kabuto Episode

The Worm attempts its signature Clock Up ability — moving at super-speed to evade attacks. Kabuto responds: "Clock Up." He matches the Worm’s speed, and the fight shifts into a frozen-time perspective where only the Riders and Worms can move normally.

Kabuto overwhelms the Worm, then ends it with his finishing move: Rider Kick — a rising, flying kick that destroys the Worm and causes it to explode.

Kagami watches in shock. Tendou detransforms, looks at him, and says nothing, walking away.

The episode opens with a flashback to 1999, when a giant meteor dubbed the "Shooting Star" is on a collision course with Earth. The Japanese government, anticipating impact, scrambles disaster protocols.

Instead of a catastrophic extinction event, the meteor breaks apart in the atmosphere. Large fragments crash into various locations, including a rural riverside. A young Souji Tendou is there with his grandmother. A massive chunk of rock lands nearby, splitting open to reveal a strange metallic object — a silver belt-like device. Inside the meteor fragment, alien worms writhe and begin to emerge.

Tendou’s grandmother takes the belt and hands it to him:

"Grandmother said this... 'Walk the path of Heaven, and rule over everything.'"

The scene cuts to a newscaster reporting the event as "the meteor that fell in Shibuya" — implying a cover-up. "I will rule over everything
