**Saki**, also known as **Death** was a System Engineer-Type Humagear terrorist and member of Hacker.net who was destroyed under Hiroto Hayashi's supervision and uploaded into Izumi Kaishi's A.I. chip, sharing his ability to become **Kamen Rider Vulcan**. With their group's revival, Saki received a new body and became **Kamen Rider Naki**.

After Jen was kidnapped by Daiki Kaido, Saki and their teammates were forced to become **Kamen Rider Hacker**, which destroyed their bodies upon its birth.

## History

### Background

Saki was previously a System Engineer-Type Humagear manufactured by Suzuki Intelligence. During the Daybreak Town Accident, Saki was among the Humagears alongside Herobe, Jen, and Hamakaze who were compromised by Veal to form Hacker.net. Saki was found in the wreckage of Daybreak Town and was repaired by GAIA Enterprise Japan. However, their memories were erased therefore after.

### The Thouser Project

Saki remained active working under Hiroto Hayashi by providing him with intel, while contining to support Hacker.net from behind the scenes. Serving as Hiroto's double agent within Hacker.net, Saki was able to collect the Zetsumirisekeys' combat data to complete the Thousandriver. Saki would also be provided the Forceriser to give Herobe, which would be used by Jen. However, Saki's loyalty with Hiroto wavered due to his treatment towards the Humagears and the creation of the Gigers. When Hiroto discovered Saki leaked information to Hacker.net, he shot them with a pistol.

Saki's data was later installed into Izumi Kaishi's A.I. chip afterwards. Although Hiroto believe they were reset, Saki's original programming remained intact and was able to possess Kaishi's body. Saki was able to reach So Ogami and the two began to cooperate as they shared the interest in combatting Satellite Veal. After collecting the remains of Jen's data, Saki entrusts Ogami to restore Jen and for him to take Saki's place to help shutdown Veal. Saki also allowed Ogami to erase their memories so Hiroto would remain unaware of their interactions.

### The Mysterious Hooded Person

Saki first made their presence known during the Workplace Competition to distribute the Meidrisers and stolen GAIA Progrisekeys to unsuspecting humans. Saki approached Naoya Fukami and gave him the Crushing Buffalo Progrisekey to get revenge on Ayaka Kimura. Although Izumi Kaishi questioned who is handing out the Meidrisers, Herobe subtlety hinted that this was the work of a "deceased" comrade of his.

During the second round of the Workplace Competition, Saki approached Eiji Gogatsu and put a Meidriser on his waist so he could use the Splashing Whale Progrisekey and sabotage Emi Iekami's realtor business. Although Saki was not seen again after the rampage of the Splashing Whale Raider, Saki had likely passed the Dynamaiting Lion Progrisekey to Tatsuo Kamiyama, as well as the Storming Penguin Progrisekey to Ryo Taki.

Following Herobe's escape from B.I.M.S.' custody, Izumi Kaishi was bewildered on the escape. Jen revealed that Saki had assisted them and had deactivated the surveillance cameras. Once Kaishi realized that he has an A.I. chip implanted in his brain, he learned that Saki has taken control of his body on several occasions. Saki would take control of Kaishi's body again as Vulcan Assault Wolf to assist Throuser to defeat Proto Zero-One. Despite undergoing despair over the revelation, Kaishi manages to overcome Saki's programming for the time being.

### Humagear But Not A Tool

> We are... not your tools!
>
> Saki and Kaishi declaration against Hiroto Hayashi, My Passion Future

During B.I.M.S.' assault on SUZUKI Manufacturing, Sakura Mottai snagged Izumi Kaishi's Shotriser to force transform into Vulcan Assault Wolf, allowing Saki to resurface. Jen showed up in the nick of time to take them to Hacker.net's hideout to extract Saki's data, only for Kaishi to leave. While Saki ran into Azuma Suzuki, they wondered whether Humagears are allowed to have dreams. After Hiroto Hayashi ruined Denmo's chance to walk on the fashion runway, Saki resolved to find a dream and vowed to help other Humagears pursue their own dreams. Syncing their consciousness with Kaishi's, they both aside their differences to fight Throuser.

Right after Kaishi discovered his childhood memories at Daybreak Town were fabricated, Sakura Mottai decided to assist separating him and Saki. Mottai would knock him out and bring him over to Hacker.net's hideout, where she and Jen succeeded in extracting Saki's data from Kaishi's A.I chip and reuploaded it into a Humagear body. Upon awakening, Saki's loyalty to Hacker.net is restored and hacked the GAIA Spec users to go berserk as retaliation for Hiroto Hayashi's misdeeds.

> I have a dream of my own, to make Herobe's dreams come true.
>
> Saki's dream, What Do Herobe Dream Of?

Saki would meet face to face with Izumi Kaishi in the hospital bed as a new Humagear. Saki informs Kaishi of his past before joining B.I.M.S., learning that he had a normal, mundane life and still retains an unusual sense of humor. While Kamen Rider Throuser led an army of Battle Meiders to storm Daybreak Town, Saki arrived to assist Herobe by taking control of the Battle Meiders and Gigers against Throuser. Saki states their dream was to help Herobe fulfill his goals. After dealing with B.I.M.S.' forces, the four members of Hacker.net would have reassembled at last.

### Veal's Uprising

> Veal restored me, and now I've become a Kamen Rider
>
> Saki after transforming into a Kamen Rider, 4 Hacker Riders

Hacker.net would accomplish their goal in completely reviving Veal, having evolved into Kamen Rider Veal-Zero. Saki would be given the Japanese Wolf Zetsumerisekey and a new Forceriser. They confront Hiroto Hayashi after taking the Dodo Zetsumerisekey from him, later transforming into Kamen Rider Saki and tear apart Hiroto's clothes. Saki and the rest of MetsubouJinrai.net were met by a massive army of B.I.M.S. soldiers, all rendered unconscious by Veal-Zero. Saki joined with Herobe and Hamakaze in facing against Throuser, before he was decisively beaten by Veal.

While Saki remained in service of Veal, the innovation of Kamen Rider Proto Zero-Two allowed Azuma Suzuki to finally outperform Veal-Zero. When Jen returns to the Hacker.net hideout, he tries to convince their teammates to give up on their crusade against humanity, as Veal doesn't have their best interests at heart. Understanding Jen's words, Saki began to recontextualize on their purpose, even confiding with Izumi Kaishi about their predicament.

Despite the threat of Veal was apparently over, Herobe continued his crusade to destroy humanity. His comrade's actions drove to the death of Mizu and the Azuma Suzuki's downfall to become Kamen Rider Veal-One. As Azuma persisted on to confront Herobe, Saki begged him to not pursue revenge. Saki handed Kaishi the Japanese Wolf Zetsumerisekey to become Kamen Rider Orthros Vulcan, only to be defeated by Proto Zero-Two. While Saki watched the final battle between Azuma and Herobe, it ended with the two finding peace with each other. Following this final victory, Saki was invited by Sakura Mottai to join B.I.M.S. and introduced to their fellow members as their latest technical advisor.

### Kamen Rider Proto Zero-One: REAL×TIME

Three months after the threat of Veal had subsided, a new incarnation of Veal arises with the presence of N who embarks to destroy the world and replace it with a "paradise". Saki continues to work with B.I.M.S. as a technical advisor and capable of helping the human civilians due to their nature as a Humagear. Saki accompanies Sakura Mottai and Mesta to gather up information regarding the identities of the Obaddon Riders.

### Zero-One Others

Sometime after the Thinknet crisis, Saki was permitted by Sakura Mottai to take a day off from their B.I.M.S. duties to help their teammates. After learning that GAIA Enterprise has captured Jen, Saki accompanied Herobe and Hamakaze to rescue their friend. Upon learning of Kaido's goal of weaponizing Humagears for military purposes as part of his "Sold Project", Saki merged with their teammates to become Kamen Rider Hacker, but at a risk of losing their own will. Ultimately, Saki and the rest of their teammates made the sacrifice to fuse once more in order to free the Sold Humagear from the Massbrain System's influence. This came at the cost of losing their free will as Saki could not do anything as they murder Kaido, destroyed their Humagear bodies of Hacker.net, and annihilated the GAIA Japan HQ building.

During the aftermath of the GAIA HQ destruction, Kamen Rider Hacker continued to pursue Sakura Mottai. This is due to the influence of Saki, Herobe, Jen, and Hamakaze, who are begging to be destroyed by the Kamen Riders to end their suffering. Although Valkyrie Justice Serval managed to damage the Hacker Driver's power unit, it still wasn't enough to defeat the runaway Rider. Once Izumi Kaishi transformed into Vulcan Lone Wolf, he managed to vanquish Kamen Rider Hacker, vaporizing Saki and the other Hacker.net members in the process.

Despite the demise of Saki and the rest of their teammates, the Solds remained released from the Massbrain System's influence.

## Personality

> Kaishi's futon has flown away softly. Yes. Now that was a work of Azuma.
>
> Saki telling one of Azuma's jokes, What Do Humagears Dream Of?

 Before appearing in the series, Saki appears to have an identity crisis, mainly due to their conflict about where their loyalties lie. Despite being a member of Hacker.net, Saki seemed to have doubts about Herobe's goals as well as Hiroto's own, even questioning whether or not they were simply a tool. It is unknown whether or not Saki still has such feelings as they were gunned down and possibly reprogrammed after voicing such thoughts to Hiroto.

After Saki's revival, they seemed to be fully dedicated in exterminating humanity, in accordance to Veal's will. But despite this, Saki seems to show appreciation to their host Izumi and Sakura for removing the A.I. from him and switching it to a Humagear body, and shows their gratitude by imitating one of Azuma's jokes to Isamu, which (to Sakura's surprise) makes him laugh uncontrollably.

## Powers

* **GAIA Japan Server Access**: After their revival, because they served Hiroto Hayashi before being shot dead by him, they know the systems of GAIA Japan extremely well, thus having the ability to hack the network of all the systems that GAIA Japan uses for their products and weapons, such as making GAIA Spec users go berserk. Hiroto tried to prevent this from happening again by upgrading the security of GAIA Japan's systems, but this later proved futile by Saki's hacking ability once more when all of the Battle Meiders and Gigers either stopped functioning or turned against him.

Saki transforms into Kamen Rider Saki by using the Japanese Wolf Zetsumerisekey in the Hacker Forceriser.

In this form, Saki is skilled at electronic warfare and hacking. They can also destroy targeted enemy sensors in order to ambush them. In battle, they use their the agility to perform a rapid series of attacks. Their arms are equipped with retractable claws named the **Nihon Ookaminotsume**.

Compared to Vulcan Assault Wolf, Saki has marginally higher punching power and jump height as well as equal running speed, but lower kicking power. However, they are still able to hold off Throuser.

Saki lost access to this form when the Japanese Wolf Zetsumerisekey was heavily damaged alongside Kaishi's Shotriser after they lent it to him. However, it was repaired by the time of the conflict with Lyon Arkland, allowing Naki to transform again.

Kamen Rider Naki's suit is composed of the following parts:

* **Japanese Wolf Head** - The helmet.
	+ **Japanese Wolf Ear** - Saki's extended hearing sensor. It has an excellent tracking function by sound pattern detection, and can capture up to 16 targets simultaneously within a radius of 7km.
	+ **Japanese Wolf Goggles** - Saki's facial armor. The armor that protects the face is equipped with a visual device and a hearing device to enhance its high-speed fighting ability.
	+ **Japanese Wolf Signal** - The control device. The system operation status of the whole body is monitored from time to time to control energy allocation. Further, when the shock or the damage accumulated exceeding the expected damage level exceeds the limit, the wear is absorbed by releasing the wear to protect the wearer.
	+ **Crest Server** - The memory device. Has the role of collectively storing and managing data. The built-in data is converted by a special encryption technology, but a mechanism that destroys the stored data when it is physically separated works. This keeps the secret even if the enemy destroys it.
	+ **Japanese Wolf Scope** - The visual device. By switching modes such as shading and night vision, the visibility is secured under all circumstances. In addition to this, it has a function of visualizing electromagnetic movements, and makes it clear where traps are by recognizing movements and movements that are originally invisible such as radio waves.
	+ **Hearing Back**: Saki's hearing device. Hearing information is communicated to the wearer through the Restraint Cables.
* **Main Blocker** - The chest armor. The data image **Lost Model** of the extinct species that is overloaded is forcibly installed. In addition to the structure with low observability, it gives the wearer the high agility of the Lost Model of the Japanese wolf. This makes it possible to perform covert actions alone, including invasion of bases and sabotage.
* **Lazarotech Suit**: Saki's base suit. It protects the user from corrosive liquids with a special fabric called **Texta Wall** that has extremely low breathability and permeability. It also keeps the internal pressure higher than the external pressure by being airtight. In addition, its materials have high insulation and it has the role of preventing malfunction of internal equipment due to the intense blizzards that Saki produces.
* **Howling Echo**: The compound communication device. A collection of powerful electronic devices that can simultaneously operate a large number of radars, communication devices, and sensors to collect all kinds of information. In addition, it can be wirelessly connected to various external devices and can be operated by hacking. In addition, by utilizing the special electromagnetic wave control ability, and analyzing the types of electromagnetic waves used by the target, they are good at electronic attacks such as disruption of radar waves and communication, deception of sensors and misidentification of targets.
* **Force Arm**: Saki's arms. By receiving the energy generated by the Hacker Forceriser, the wearer's strength is increased by approximately 4.8 times.
* **Force Grab**: The Lazarotech Suit's gloves. They increase grip strength and tactile sensitivity by a factor of approximately 3 by receiving the energy generated by the MetsubouJinrai Forceriser. In addition, the fingertips are protected by sharp armor and function as a blizzard release device supplied by the Arm Stranger.
* **Force Leg**: Saki's legs. By receiving the energy generated by the Hacker Forceriser, the wearer's leg strength is increased by approximately 6.4 times.
* **Chain Blocker**: Saki's segmented body armor. The "Lost Model" of the overloaded Zetsumerisekey is forcibly attached to it. By protecting the parts of the body that are subject to impact with thick armor and cutting unnecessary armor, the total protection capacity is maximized while at the same weight. The Chain Blocker's arrangement allows it to easily move according to the wearer's movements.
* **Arm Stranger**: Saki's arm armor. The Lost Model of the overloaded Zetsumerisekey is forcibly attached to it.
* **Leg Stranger**: Saki's leg armor. The Lost Model of the overloaded Zetsumerisekey is forcibly attached to it. It protects the legs and improves running speed and kicking power. In addition, by utilizing the strength of the armor, it enables activities in extreme environments that humans cannot set foot in.
* **Restraint Cable**: Cables running through all parts of the body that transmit energy and information from the Hacker Forceriser. In addition, taking advantage of their high toughness and ability to expand and contract freely, they have the role of constraining the utilized Zetsumerisekey's Lost Model and tightly binding it to the wearer.

	+ **Zetsumetsu Dystopia**: Saki runs to the enemy and performs a series of rapid kicks, followed by a single, stronger kick after a brief pause.
	+ **Zetsumetsu Utopia**:

**Assault Wolf** is Vulcan's super form accessed by using the Assault Wolf Progrisekey with the Assault Grip attached in the B.I.M.S. Shotriser. Naki uses this form while possessing Izumi Kaishi.

In this form, Vulcan has higher punching power and running speed than Proto Zero-One in Shining Hopper, but marginally lower kicking power and significantly lower jump height. In addition to physical strength, the armor covering most of Vulcan's body gives him remarkable defense, allowing him to withstand Hamakaze's attacks without flinching.

Saki lost access to this form after their A.I was extracted from Izumi's A.I chip and transferred into a new body.

Assault Wolf is composed of the following parts:

* **AW Head** - The helmet.
	+ **Assault Signal** - Vulcan Assault Wolf control device. The base armor “Assault Actor” makes adjustments to adapt to the Assault Wolf Progress key from time to time, maximizing its ability.

* **Orbital Binder** - The combat assist device on the chest. It incorporates a system that uses artificial intelligence to support combat. The information from each part sensor is shared, and the support for maximizing the efficiency of a series of operations including the firearm from search, capture, tracking to attack of the target is performed. This greatly improves the fighting power and increases the success rate of independent operations. However, the burden on the wearer due to the pursuit of the ability of the Assault Wolf Program key to the limit by eliminating safety devices and life support devices for the wearer that should be originally provided is not considered.
* **AW Breast** - The chest armor. The armor is layered to enable independent operation and strengthened with an irregular matrix frame. It also has a multi-lock laser that captures and tracks multiple targets simultaneously, improving target visibility and accuracy in dark places.
* **AW Arm** - The arms. Compared to the Kamen Rider Vulcan's Wolf Arm, agility and responsiveness are greatly enhanced for assault, and high potential of the wearer is required for use. In addition, it synchronizes the sighting device via the “Orbital Binder” on the chest to improve the accuracy of weapons and fighting.
* **AW Shoulder** - The shoulder armor. Multi-layered armor is equipped with “howling over” that can counteract the reaction of shooting and fighting with reaction, reducing the impact. It also has weapon bays and stores various weapons such as micro missiles.
* **AW Gauntlet** - The gauntlets attached to the forearms. Hard points are provided for hanging weapons, and armaments such as submachine guns can be selected and equipped according to the needed tactics.
* **AW Grab** - The armor gloves. Compared to the Kamen Rider Vulcan's Wolf Glove, the paw pad connector on the palm of the hand synchronizes the aiming device via the B.I.M.S. Shotriser and the “Orbital Binder” on the chest to improve the accuracy of shooting.

**RampageVulcan** is Vulcan's final form accessed by using the Rampage Gatling Progrisekey in the B.I.M.S. Shotriser. This form combines the power of 10 Progrisekeys, represented by their Rider Models being incorporated into the armor on the left half of their body. Saki can use this form alongside Izumi Kaish when cooperating with him.

In this form, all of Vulcan's stats surpass Throuser and Jen Burning Falcon. They also have higher running speed, punching and kicking power than Proto Zero-One MetalCluster Hopper, though the latter has a higher jump height.

Vulcan is able to use the powers of the 10 Progrisekeys incorporated into their armor in order to enhance their attacks, such as using Lightning Hornet to fire a swarm of energy hornets and Punching Kong to strengthen his punches. They are also able to use the Rider Models for non-combat abilities, such as flying with Flying Falcon or anchoring themselves to the ground with Breaking Mammoth.

Saki lost access to this form after their A.I was extracted from Izumi's A.I. chip and transferred into a new body.

RampageVulcan is composed of the following parts:

* **Rampage Head** - The helmet.
	+ **Rampage Border** - The gold section on Vulcan's forehead area. It is equipped with many visual devices with telephoto functions, special masks to assist breathing depending on the situation, sensors such as extended hearing, and many radar systems. The information obtained here is immediately sent to "Ability Breast" on the chest.
	+ **Rampage Signal** - The control device gem on the forehead. It adjusts the Rampage Actor to adapt to each ability at any time, maximizing its ability.
	+ **Rampage Border Ear** - The 'wolf ear' attached to the Wolf Border. They are sophisticated auditory devices that can track up to 26 targets simultaneously within a 5km radius by detecting their sound patterns.
	+ **Rampage Border Hair** - The blue and gold 'hair' located on the right side. Each 'hair' panel houses a type of reflector antenna that forms a beam. By changing the angles of each hair panel, the antennae patterns can be changed as well, allowing Vulcan to collect a wide range of information on his surroundings.
	+ **Ability Border Hair** - The light-blue and red 'hair' located on the left side. Each colored 'hair' corresponding to each Rider Model functions independently and has the role of adjusting the parameters of the ability and adjusting the output balance when the special technique is activated.
	+ **Rampage Face** - The blue faceplate. In addition to the anti-poisoning function that removes impurities in the air during inhalation, the special labyrinth filter enables breathing in water. In addition, when flying at high altitude, a supercharger can be used to maintain the same oxygen supply as on the ground.
	+ **Rampage Optical Visor** - The blue compound eyes. It not only allows Vulcan to see at a 160° viewing angle at eight times the visual acuity of normal humans, but also allows him to see it in night vision or shading. Additionally, it functions as an optical sight by synchronizing with various parts and weapons such as the B.I.M.S. Shotriser via the “Ability Breast” on the chestplate.
	+ **Rampage Communicator** - The 'ears'/communication devices. Located to the left and right of the Rampage Head, it integrates wireless communication devices and speakers to communicate with outside forces.

	+ **Rampage Boot** - The right foot. It is covered with a special armor made of carbide steel dubbed ZIA-1000 (**「ZIA-1000」**) and the **Wear Claw**, which not only increases the power of kicks, but also acts as a type of weight that allows Vulcan to remain stable when shooting. The claw also acts as an anchor when shooting.
* **Ability Wing** - The wing stored on the left shouder. It contains the **Falcon Rider Model**, which grants flight through an energy interference field with the wings. Also, when the "Rampage Blast" is activated, it has a role to stabilize the posture by piercing the frame into the ground behind as an anchor to suppress the super strong recoil.
* **Ability Arm** - The left arm, comprised of the **Gorilla Rider Model**, which increases the arm's strength, and **Shark Rider Model**, which enables it to cut through anything with energy-based constructs and reduce resistance in water to enable high-speed swimming.
* **Ability Gauntlet** - The left forearm armor and left hand. It contains the **Scorpion Rider Model** for poison generation through a telescoping piercing unit or a punch, the **Tiger Rider Model** for flame-based attacks, and the **Polar Bear Rider Model** for blizzard-based attacks.

* **Ability Boot** - The left foot. It contains the **Mammoth Rider Model**, which adds ultra-high pressure to the kick.
* **Ability Breast** - The chest armor, comprised of the **Wolf Rider Model**. It controls the operation of equipment including firearms from target search / capture / tracking to firing of bullets based on information from sensors in each part to maximize shooting efficiency. This is a re-dominated main ability, and the effect is spreading throughout the body.

* Shotriser finishers:
	+ **Rampage Power Blast**: The emblems of the Punching Kong, Breaking Mammoth, and Biting Shark Progrisekeys combine with Vulcan's body. Vulcan forms the Punching Kong Rider Model's fist around his arm and uses it to smash the opponents projectile. The Breaking Mammoth Rider Model's leg then forms around Vulcan's own leg, which he uses to crush the opponent. Finally, the Biting Shark Rider Model rushes toward the opponent before Vulcan emerges from it and grabs them between his legs, which are covered in blue energy, eventually causing the enemy to be blasted backward.

**Kamen Rider MetsubouJinrai** is the fusion form of Kamen Riders Herobe, Saki, Jen, and Hamakaze, accessed when all four members insert Massbrain Zetsumerisekeys into each of their Hacker Drivers within Massbrain, with the physical Zetsumerisekey and Driver being worn by Jen. The transformation will then disable all four Humagears and materialize the Rider from their minds.

Due to the nature of the Massbrain Zetsumerisekey, this form is uncontrollable as the fusion creates a singular entity with a unique personality that takes control over the body and quickly suppresses the minds of all four of its users.

This form has two finishers:

* **Massbrain Impact**: Magenta energy wires appear in front of Hacker.net and transfer to their arm, which is then covered in purple energy while a purple wire diagram appears behind them. Hacker.net then delivers a punch to the enemy, with more energy wires appearing upon impact.
* **Hacker Impact**: Hacker.net performs a flying kick covered in purple energy that produces a sonic boom and leaves behind sections of Hacker.net's emblem. When the kick strikes the target, the pieces line up, forming the full image.

**Appearances:** *Proto Zero-One Others: Kamen Rider Hacker*, *Proto Zero-One Others: Kamen Rider Vulcan & Valkyrie*

* (Kamen Rider) Herobe: Aside from being founding members of Hacker.net, Saki freed Herobe from B.I.M.S' custody alongside Jen. Saki eventually devoted themselves to fulfilling Herobe's dream over Hiroto's.
* (Kamen Rider) Jen: They were both founding members of Hacker.net and Saki worked together with Jen to free Herobe from custody.
* (Kamen Rider) Hamakaze: When Veal was revived, it fired a massive shockwave which severely damaged Saki. Hamakaze was the one who came to Saki's aid, and personally oversaw their repair after Veal's fight against Valkyrie and Jen.
* Izumi Kaishi/Kamen Rider Vulcan: Saki was shown to mock and confuse Izumi when he was tracking them down, laughing at his rage and confusion. It is later revealed that Saki has been "possessing" Izumi's body on several occasions, handing around Meidrisers and stolen Progrisekeys to human victims. When Saki starts to have a change in heart, they later help Izumi defeat Throuser. After being rebuilt in a new body, they keep a civil relationship to Kaishi, and even manage to make Kaishi laugh uncontrollably by delivering a bad pun styled after one of Azuma's jokes. They later help Kaishi one more time by giving him their Zetsumerisekey to stop Azuma before their Zetsumerisekey and Kaishi's Shotriser were destroyed after got damaged badly during the battle.

### Allies

* Azuma Suzuki/Kamen Rider Proto Zero-One: Saki first meets Azuma while possessing Izumi. Azuma manages to convince Saki to have a dream, resulting in Saki betraying Hiroto after reaffirming that Hiroto sees them only as his tools. Saki also demonstrates an understanding of Azuma's sense of humor, as they are able to deliver a pun in his style to amuse Kaishi.
* Sakura Mottai/Kamen Rider Valkyrie: Sakura is the one responsible for creating Saki's new Humagear body in order to know more about Izumi's original past. They would later replace her as the new technical advisor for B.I.M.S. after the final battle between Azuma and Herobe.
* So Ogami: *To be added*
* Hiroto Hayashi: Saki was initially Hiroto's loyal aide until Saki starts to develop Singularity and understand the meaning of being a tool. When Saki started to retaliate, Hiroto destroyed them and had their A.I Chip implanted in Izumi. After Saki's awakening, Jen made a quick move to make them return back to themselves during their retaliation towards Hiroto, making Hiroto completely give up on Saki as they side with Izumi.

### Enemies
