"I will destroy this world... and build a paradise."
―S's proclamation to create a paradise on Earth[src]

Rihito Isshiki (一色 理人, Isshiki Rihito)[1], also known as S (エス, Esu) was the central antagonist of Kamen Rider Zero-One: REAL×TIME who transforms into Kamen Rider Eden (仮面ライダーエデン, Kamen Raidā Eden)[2].



Rihito Isshiki was a kind scientist working for Nano MIRAI, one of the several companies in charge of developing the Ark. Rihito studied in AI-controlled nanomachines as well as used them in human medical trials. His fiancé, Akane Tono was struck with an unidentified illness and Rihito wanted to use nanomachine technology to cure her condition. However, as a result of the Daybreak Town Accident , it didn't only infected Humagears but also the nanomachines, eventually killed Akane inside her body. Desperate to bring her back, Rihito digitized his mind into nanomachines, becoming S. Rihito Isshiki is presumed dead by the public when his decomposing corpse is discovered later.

S and his followers.

Overtime, S forms Thinknet, hooking up its servers to Akane's brain and digitizing her. Many people flocked to Thinknet, forming an army with which S could fulfill his plans.

Bringing Paradise

Sometime after the tensions between humans and Humagear ended with Aruto Hiden and Horobi's battle, Azu arrives to grant S a Zero-One Driver and Zetsumerisekey. He transfigured the belt into the Eden Driver and transformed into Kamen Rider Eden. S proclaims his wish to destroy the current world to build a "paradise" on Earth.

Video message from S

S sends a video message to Aruto Hiden announcing his intentions to destroy the world in sixty minutes. As he commands the Kamen Rider Abaddons to attack cities worldwide, Aruto arrives as Kamen Rider Zero-Two and fought S, as Kamen Rider Eden. Zero-Two is defeated by the Eden Impact, and gets his Zero-Two Driver taken. Eden takes the Zero-Two Progrisekey and began downloading data from Zea, throwing Aruto out of the picture as he continues the congregation.

S finished downloading Zea's data and creates the Hellrise Key. Aruto reappears and questions what the paradise S is creating is supposed to be. S transforms into Eden once again into as Aruto transforms into Zero-One MetalCluster Hopper. As they battle, Zero-One is able to immobilize Eden from his nanomachine regeneration. Eden manages to escape using the completed Hellrise Progrisekey, before destroying the building they are in and the majority of his followers. Aruto continued to follow S at an abandoned chapel and tries to stop him from using Hellrise Progrisekey by transforming with it, turning into Zero-One Hellrising Hopper and overpowered Eden as his opponent went on an animalistic rampage.

S chooses his own end

Fortunately, he was saved by Izu as Zero-Two, who stepped in before he could kill S, helping Aruto regain control. While S takes the Hellrise Progrisekey, Aruto understood his true motivations was to create a virtual paradise for him and his wife to live in. S would be convinced by Aruto that Akane doesn't want a world like this, and that she doesn't hate him for not managing to save her from death. After a moment of contemplation, S tries to stop the destruction, only to be stopped by Behru and his former followers, who decided to resume their goals to create their digital paradise. Aruto and Izu help S in order to spend his final moments with Akane as they both engage Kamen Rider Lucifer and the Abaddon Riders to allow him reunite with Akane at the Thinknet servers.

Final Moments

Rihito Isshiki and Akane Tono's wedding

S escapes the chapel and heads to the Thinknet servers, narrowly avoiding attacks by more Abaddons. S transports himself into the virtual world and into the chapel within, only to believe Akane nowhere to be found. Before S could despair into sadness as Akane, walks up the aisle and hugs him, dressed in bridal wear. S apologizes for not saving her and Akane says it's not his fault. S stands up and, now donning white groom wear, slides the ring onto his fiancee's finger and embraces her in their final moments. The Thinknet servers explode soon after, deactivating all of the Abaddons.

Before the Daybreak Town Accident, Rihito was once a kind man who deeply loved his fiancé, Akane, did the best he could to save her from her condition. After her death, Rihito was wracked with guilt and depression for inadvertently causing Akane's death. Since then, he was desperate to bring her back, even when it meant that he had to become a monster, which attracted Azu to recruit him as the next Ark.

As S, he is a charismatic and mysterious individual who is seen by his followers as an enlightened figure. He preaches of creating paradise, which he calls the "Paradise Guardia", inspiring loyalty in his followers. However, despite his utilitarian goals, S' love for Akane did not vanish and sought to create a virtual paradise for him and his wife to live in. S was willing to digitize people from the real world to populate his virtual realm without considering their own free will. However, while acting as a tremendous symbol, he was planning to abandon his followers in Thinknet in the ruined world, considering them a nuisance to his virtual paradise.

When Aruto discovered his true motives, S realized that his actions were out of selfish gain and should let Akane rest in peace. In the digital world, S was able to reunite with Akane and spent his final moments to embrace her, bringing back the good man that was previously Rihito Isshiki.



Eden Regeneration

  • Regeneration: Since his new body is made of nanomachines, Eden can repair his body at an extremely fast rate whenever he takes damage.
  • Nanomachine Control: Eden has absolute control over the nanomachines that make up his body, allowing him to fashion contructs like small blades and massive spikes to attack foes with. His nanomachines typically take the form of a blood red liquid but can also be hardened like a solid or scattered like a gas, as seen with the Abbadon Riders’ gas bombs.


  • Cluster Cells: While Eden regenerates his body, Zero-One MetalCluster Hopper is able to send Cluster Cells to momentarily paralyze him, making him vulnerable to any attacks for a brief amount of time.

S transforms into Kamen Rider Eden by using the Eden Zetsumerisekey in the Eden Driver.

Stat-wise, Eden is actually weaker than Zero-One MetalCluster Hopper in all areas. However, due to S being an avatar made of nanomachines, Eden has the ability to regenerate from virtually any injury. This ability allows Eden to defeat Zero-Two despite the latter being much stronger. Eden is also able to form bladed constructs out of the nanomachines from his body or surrounding area to attack the opponent in battle.

However, Eden's regeneration ability has two weaknesses, each of which is exploited by one of Zero-One's forms: MetalCluster Hopper can swarm Eden with Cluster Cells that constantly tear away at his body without pause, making him unable to fully recover. Hellrising Hopper is able to release all of the energy it has accumulated in a large explosion that damages all of Eden's body simultaneously, overwhelming his ability to reconstruct himself. This attack is the only thing that been shown to be able to force Eden out of transformation.

Eden wields the Thousand Jacker as his personal weapon.

Eden has the following finishers:

  • Eden Driver finishers:
    • Eden Impact (エデンインパクト, Eden Inpakuto): Eden lets a single drop of his nanomachines fall from his fingers. When it hits the floor, the surrounding area is flooded by the nanomachines, appearing like a pool of blood. Large spikes then emerge and follow the opponent's position. Once the enemy is trapped between spikes, they merge to form a dome that imprisons them. The dome enlarges before Eden closes his fist, causing it to quickly implode and leave behind a spray of the nanomachines in their liquid state.
  • Thousand Jacker finishers:
    • Thousand Break (サウザンドブレイク, Sauzandobureiku): Eden inserts a Progrisekey into the Thousand Jacker, pulls the hilt, and performs an attack utilizing the power of the inserted Progrise Key.
      • Hellrise: Eden charges the Thousand Jacker with purple and red energy before pointing it upward, creating a pillar of light that extends miles into the sky and is surrounded by rings of red energy and spiraling red lightning. With the pillar of light anchored to the tip of the Thousand Jacker, Eden draws a circle in the air with the weapon, creating two rings of distortion above him. Finally, Eden stabs the Thousand Jacker into the ground, causing dark purple energy to travel back down the pillar of light. When the energy reaches the base of the pillar, it results in an explosion that sends out massive shockwaves of purple energy which destroy the surrounding area.

Behind the Scenes


S is portrayed by Hideaki Ito (伊藤 英明, Itō Hideaki). As Kamen Rider Eden, his suit actor is Yuji Nakata (中田 裕士, Nakata Yūji), who previously served as the suit actor for Kamen Rider Thouser.


This character's various names appear to have ties to the concept of the Bible:

  • Kamen Rider Eden's name comes from the Garden of Eden.
  • The katakana of S (エス, Esu) might have derived from the Japanese pronunciation for Jesus Christ (エス・キリスト, Iesu Kirisuto).
  • Also the alternative reading of his given name, S, is the first letter of Satan and Serpent, the antagonistic figures on the Garden of Eden.

Concept Art

Eden's suit as it glows in the dark.

  • Eden's suit has the same base design as Kamen Rider Zero-One and Kamen Rider Thouser, except with thigh armor recycled from Flying Falcon, as well as new arm and torso armor and a new helmet.
  • Eden's suit is primarily a dark metallic blue with a black under suit, in addition to having white and dark red accent lines across his armor. However, the lines on his suit illuminate in a uniform magenta color instead, giving the illusion of the suit appearing more purple than black and blue.
  • According to producer Takahito Omori, Kamen Rider Eden's actual design motif is a human to make it a contrast with most of the series' Riders so far. He also added that the red lines on its body were meant to emulate blood vessels. Despite being the initial antagonist, Eden was purposely designed to appear heroic instead of monstrous.[4]
    • In addition, Eden was originally meant to resemble an extinct animal, but this concept was dropped in favor of the aforementioned human design, so as to emulate Eden's desire to eradicate mankind.
  • Rihito's speech in the movie emulates the Old Testament, according to producer Takahito Omori.[5]
  • Both Eden and Lucifer use the same zetsumerisekey and driver to transform.
    • Eden and Lucifer is both a reference to the Garden of Eden and Lucifer in its snake form.
