Kiriya Kujo (九条 貴利矢 Kujō Kiriya), also spelt as Kiriya Kujyo, was a medical examiner of Seito University Hospital. He obtained a Gamer Driver and the Bakusou Bike Gashat to transform into Kamen Rider Lazer (仮面ライダーレーザー Kamen Raidā Rēzā).

Character HistoryEdit


Before Zero Day took place, Kiriya once told his friend Jungo that he was infected by a new infection - the Game Disease, which was a potentially fatal virus. Unable to accept the reality that he was going to die, Jungo freaked out and ran away, leading to his death in a traffic accident. Kiriya was devastated by the passing of his friend, and grieved over Jungo at the morgue. He blamed himself for revealing the truth, and lamented that his friend would not have died had he kept it to himself. Consequently, the incident caused Kiriya to believe that telling the truth might not always be the best thing to do. The Reason for Some Lies!

Later, Kiriya Kujo found out about Zero Day and the Bugster three years before the series. Confronting Kuroto Dan about this information, he blackmailed Dan into giving him a Gamer Driver and the Bakusou Bike Gashat in exchange for his silence. An Operation Called Dash!

Present, Observation as CivilianEdit

Kiriya appeared at the abandoned venue for the Mighty Action X launch party following the Bugster's rampage, voicing to himself that things are getting interesting and that everyone is raring to start the race. I'm a Kamen Rider!

From afar, he later witnessed Ex-Aid and Brave's battle against the Aranbura Bugster which was interrupted by Kamen Rider Genm, observing that everyone is getting "super pumped up". Another Prodigy with No Thank You?

Seeing Snipe's debut make four players, he noted that it was about time to start the race. BANG, That Jerk is Coming!

Debut As Lazer, First Encounter with GenmEdit

Kiriya appeared in Pediatrics along with the patient, Yoshitaka Nishiwaki, surprising Emu. Kiriya states that he wants to meet with the Genius Gamer, calling him 'Expert'. He wants Emu to save the patient, and in return he'll retrieve Emu Gashat from Taiga.

Kiriya later shows at Taiga's base and asks him for a duel for Emu's Gashat to which Taiga agrees (off-screen).

Kiriya, along with Taiga then show up at a park where Emu, Asuna, Yoshitaka and Hiiro were. When Taiga asked the reason Kiriya helps the patient, the latter states that his friend was also one of the victims of Zero Day & he won't let another person suffer the same fate as him,especially after he saw Graphite kidnapped Yoshitaka's sister, Riko & infected him with the Bugster virus. Suddenly, Yoshitaka turns into a giant Bugster and Kiriya, along with Taiga transformed into Kamen Riders Lazer Level 1 and Snipe Level 1 respectively.

Using the Instigate Energy Item, Lazer manages to extract Motor Bugster from Yoshitaka, but finds out that he's unable to stop spinning. Motor then stops him before trying to run. Lazer then levels up into Level 2, which takes the form of a racing bike, astonishing all the riders. Lazer orders Emu to ride him, but Emu decides to save Nishiwaki first, much to his dismay. Lazer then tries to chase himself, but Motors has already escaped.

Kiriya later shows up in CR front door, complaining Emu that he lost Motor's track. Emu however convinces him that since his Gashat is racing themed, he could actually challenge him to a race. Hearing this, Kiriya brightens and immediately offers his friendship with Emu, which Emu gladly agrees.

Kiriya then transforms into Lazer Level 1 and goes to Level 2 directly, prompting Emu to ride him. Emu selects the stage and faces Motor in a race. After Emu transforms into Ex-Aid Level 2, they stop Motor Bugster using a perfect conjunction of High-Jump Energy Item and Gashacon Breaker. Ex-Aid helps Lazer to execute Critical Strike and defeat Motor, saving Riko in process.

However, after they won, Lazer threw them off and reverts to Level 1. When asked by Ex-Aid, he reveals that he made up the story about his friend and renounces his friendship with Emu. All he wants is to obtain a sample of the Bugster virus to learn more about them. However, before he is able to achieve his goal, Genm appears, destroying the dying Bugster in the process. Genm then transforms into Sports Action Gamer Level 3 and using Shakariki Critical Strike, Genm managed to almost deplete Lazer & Ex-Aid's Rider Gauges. Kiriya states that it's still early for a Game Over, and cancels his transformation. An Operation Called Dash!

Second Encounter with GenmEdit

Kiriya, along with Taiga are shown at Dan office, already holding the special stethoscope and overheard Dan's conversation with Poppi Pipopapo. Taiga said that he'll claim all the stolen Gashats himself before he took his leave. Kiriya ask Dan if it's alright to count him in, which the latter said that he had no choice. Kiriya states that it's fine by him, he only want to know what behind the Bugsters.

Later, Kiriya was seen walking around a park when he saw the gashat thief passing by him. He then decide to follow the thief. Getting the info he needed, he comes to Emu, Hiiro and Asuna. Emu get bewildered as he remember him. Kiriya lightheartedly states that Emu won't find the Thief right now and even jokingly comment that Emu doesn't need to be so angry. He then say that he secretly spies the Gashat thief, and deduces that Genm's true identity is none other than the thief himself.

Kiriya appeared at the park where Emu, Hiiro, Asuna and even Taiga confront the Robots Bugster. He decline Taiga challenge as he had to fight with Genm, who appeared not too long after, already in Sports Action Gamer Level 3. Kiriya transformed into Lazer Level 1 to fight with Black Ex-Aid, alone. He taunts the black Rider about the fact that he know his true identity, which the latter became shocked. However, Genm's sheer power is too much for Lazer as he beat Lazer badly, knocking him unconscious as Kiriya cancels his transformation. Everyone Gathers for a Clashing Crash!

Kiriya is seen is Seito hospital room, where he still lay unconscious, recovering from his injury earlier. A Hollow Beating in the Heart!

Become Chambara Bike Gamer Level 3, Third Encounter with GenmEdit

Kiriya awoke after receiving a nightmare about his friend death five years ago. And he immidiately knows that he stayed in a hospital room alongside an old man patient, Yoshio. Learning his relationship with his daughter, Shiori, Kiriya had his heart moved to help the patient once he noticed that the old man was infected with the Bugster virus. However, people in CR, in exception of Haima (the latter is still obvious about Kiriya) starts to not believe him. First, because he lied about his friend's death during Zero Day (although this is half true). Second, because he lied about Genm's identity to be Graphite. Kiriya claims that sometimes, you need to lie in order to make things better. However, people in CR leave him alone, much to his dismay.

After Ex-Aid and Brave extract Chambara and Combat Collabos from Yoshio, Kiriya heard Emu's explanation about the Game disease. This reminds him about his past, when he's too honest that ultimately leads his friend, Jungo to death. Kiriya punched the wall in rage, before he decides to confront Emu. Kiriya then explains about why Emu needed to lie once in a while, and explained that Yoshio use a lie to his daughter, Shiori to make her start anew. As Asuna reports that the bugster is on the loose, Kiriya say that the Bugster is about to attack Shiori, which turns out to be true.

File:Kiriya's revenge.png

Kiriya convinced Emu and Hiiro about saving the old man together, only to have Emu accept the help. With the help from Ex-Aid, Lazer was finally able to fight properly alone with the upgrade by using the Giri Giri Chambara Gashat to change into Chambara Bike Gamer Level 3 after destroying Chambara Collabos Bugster, facing Genm Sports Action Gamer Level 3. Kiriya revealed the truth that Black Ex-Aid is Kuroto. But thanks to the plot from Parad, Kiriya was disbelieved by Hiiro as Parad took Kuroto's Gamer Driver after the massive explosion from Lazer's Giri Giri Critical Finish. Leaving him with no other choice, he forcefully said another lie to Emu before he took his leave. Unbeknownst to him, Emu was still trying to trust Kiriya without his notice. The Reason for Some Lies!

Fourth Encounter With Genm, The truth about Doctor Rider SystemEdit

Kiriya contacted Kuroto Dan, to presumably black-mail him. Then, Dan appeared below a bridge, and meet Kiriya. Kiriya angrily states that thanks to Dan's plotting, everyone now labeled him as liar. Dan simply said that he deserve that. Kiriya gives a fake laugh and asks who is the guy that substituting him. Dan said that it's none of Kiriya's business anyway. So, Kiriya and Dan finally transformed into Lazer Chambara Bike Gamer Level 3 and Genm Sports Action Gamer Level 3 and fight.

As Genm is finally overpowered by Lazer's sheer power. They decide to end the match using Giri Giri Critical Finish & Shakariki Critical Strike, which ended in a draw. Kiriya asked why did Dan ally with the Bugsters, Dan said that it's to know the origin of the Bugsters, the same Kiriya wants to do. Dan also mentioned that for the one who becomes a Kamen Rider, they must undergo a compatibility surgery. Which means, all of them had undergone that surgery, except for one. Kiriya realized that the one Dan talking about is none other than the Genius Gamer himself, Emu Hojo. Men, Fly High!

The Drago Knight HuntersEdit

His curiosity piqued, Kiriya began searching for the cause of Emu's unique condition. Under the guise of determining a cause of death, Kiriya got Emu's medical records from the hospital and began investigating the only surgery in the records. The search led him to Kyotaro Hinata, the current director of the Ministry of Health and the surgeon who performed the operation. Kiriya found Hinata in CR due to the latter's Bugster infection, but it is unknown what information he learned. Beat Up the Dragon!

Soon after, Kiriya witnessed the widespread infection caused by Graphite, threatening to cause a second Zero Day. Transforming into Lazer Chambara Bike Gamer Level 3, joined Brave Level 2 and Snipe Combat Shooting Gamer Level 3 in fighting Graphite. However, Graphite's increased strength from the Proto Drago Knight Hunter Z Gashat, combined with Brave and Snipe's squabbling, rendered the three Riders no match for the Bugster. Lazer was able to take the Gekitotsu Robots Gashat from Snipe during the commotion. Back in the real world, the three were approached by the apologetic Emu, who asked for their help in using the Drago Knight Hunter Z Gashat. Hiiro refused out of pride, Taiga wasn't interested in playing doctor, and Kiriya cited Emu's condition as a reason not to trust him.

Later that night, Emu called Kiriya, offering him the Drago Knight Hunter Z Gashat. However, Kiriya arrived the next day to find that Emu had tricked him, Taiga, and Hiiro by offering them the Gashat as well. Emu offered the Gashat to whomever could beat him first. Transforming into Lazer Chambara Bike Gamer Level 3, Kiriya joined the other two Riders in fighting Ex-Aid Hunter Action Gamer Level 5 Full Dragon. Eventually, they were able to separate the Hunter Gamer from Ex-Aid and attacked it. Much to their surprise, Hunter Gamer split into four virtual Gashats, one for each Rider. Ex-Aid explained his true plan: getting the four together to see who could take out Graphite. Transforming into their Level 5 forms, the Riders were finally able to fight on par with Graphite, although their lack of cohesion got in the way. Ultimately, the four were able to defeat Graphite once and for all, although none could agree on who delivered the final blow. Uneven Doctors!

Genm Identity RevelationEdit

Who's the Black Kamen Rider?

Fifth Encounter With Genm, Lazer's Last Fight And DeathEdit

Kiriya was about to leave when Emu called him. Emu said that he felt ashamed that he had doubted Kiriya, and that he'll trust Kiriya from now on. Kiriya complies gleefully and asked Emu to return Shuuhei's smile. Later, Kiriya visited a prison and met with Kuroto's father, Dan Masamune, also known as the former CEO of Genm Corp. The information Kiriya got from him relates to the first origin of Bugsters back in 2000, Emu's past surgery by Kyotaro where Masamune and Kuroto involved, the beginning of Kuroto's evil scheme relating to Next Genome's unrecorded experiment on Emu's comatose body which unleashes the earliest Zero Day in 2010 and framed his father for this in 2011.

He later asked the other three Riders to meet up with him and tell them the information he got. He then encountered Kuroto Dan in a warehouse some time after leaving the prison. Kiriya then said that Kuroto is responsible for giving Emu the compability surgery. Dan then said that Kiriya knows too much, but decided to give Kiriya a Christmas present, which is the Dangerous Zombie Gashat. Kiriya took the Gashat, kicked the Gashat container, and transformed into Lazer Level 1. However, when Kiriya inserts the Gashat into his Gamer Driver, the Gashat consumed his Rider Gauge, leaving him with very little Gauge energy. Kuroto took the Gashat back, claiming that Kiriya is indeed a stupid person. With the empowered Gashat, the Gashacon Bugvisor and the Bugster Buckle, Kuroto transformed into Genm Zombie Gamer Level X. Having no choice, Kiriya transformed into Lazer Chambara Bike Gamer Level 3 and fight Genm.

File:Dying Kiriya.jpg

The fight turned out to be in Genm's favor, as Lazer is overpowered by him. Genm even stole Lazer's Gashacon Sparrow and throws Giri Giri Chambara away when Lazer tried to finish him with Giri Giri Critical Finish. Genm then performs a Critical End and depletes Lazer's Rider Gauge to zero. Kiriya is forcefully untransformed and despite being badly beaten up, he is still trying to fight Genm, to no avail. As Emu, Hiiro, Asuna and Taiga came to the battle location, Kiriya apologized to Jungo and said that he'll soon join him in the afterlife. As Genm left, Kiriya's body starts to dissolve and using his last strength, Kiriya gave Emu his Gamer Driver and his Bakusou Bike Gashat. Kiriya said to Emu that he is himself and that he leaves his fate to him, before he finally dies. His body then vanishes into data, while Emu weeps over him in the heavy rain as the others look in shock. Christmas Special: Targeting the Silver X mas!

Luckily before his death, Kiriya already developed a program which can counteract the infection of the Bugster Virus. He left this to his colleague Yoshitaka in which he provided later on to Hiiro. This program was later used as a main component for the creation of the incomplete the Mighty Maximum X Gashat. Engineered History!

Powers and AbilitiesEdit

  • Acquired Game Disease Immunity: As a result of the standard compatibility surgery for CR candidates, Kiriya Kujo is immune to the Game Disease, and able to transform into a Kamen Rider to fight the Bugsters.


Kiriya is an easy-going man whose lighthearted attitude hides a sharp intellect and cunning nature. As such, he is a manipulative individual and also a very convincing liar who will use dirty tactics to get what he wants, including deceit and sabotage. His deceitful personality actually developed from the trauma he experienced five years ago when his friend Jungo died from an accident when he freaked out over the possibility of dying from the Bugster infection. He also states to Emu and the others that he just tried to protect all of them from the harsh truth, showing that he actually didn't want his comrades to get hurt.

However, he still cares for his patients as shown when he found out that Nishiwaki's sister was kidnapped by Graphite and also Yoshio. But even then it did not stop from being opportunistic and self-serving. He had the habitual quirk to drape his dull red leather jacket over his shoulders without putting his arms through the sleeves, and to wear round sunglasses whenever he is observing something, but he'll put his jacket on properly and discard his sunglasses whenever he needs to be serious or fight.

But despite his tremendous mental strengths, Kiriya suffers from a great deal of pride that he gets from the knowledge he obtains. This in turn causes him to become blind to his own weaknesses and the strengths of the people he believes to have leverage on. When he is serious enough, he won't lie. However, if someone outsmarts him or the situation turns against him to give the impression that he had been lying, he'll resort back to lying. This often leads to him casually claiming that he did in fact lie before instead of trying to defend his innocence, showing that he doesn't really care what other people think of him.

Unlike the other riders, in this form, a prototype of Chambara Gamer combines with Lazer, becoming his rider form.

Lazer's stats were raised significantly, although his speed is lowered a bit. He compensates this by using his Gashacon Sparrow.

Since this Gashat gives Lazer a Rider form, he usually uses this form when he is fighting alone.

This form has two finishers:

  • Kimewaza Slot Holder finisher:
    • Giri Giri Critical Strike (ギリギリクリティカルストライク Giri Giri Kuritikaru Sutoraiku, Slash Slash Critical Strike):
  • Gashacon Sparrow finisher:

      • Sickle: Lazer delivers a powerful energy double slash to the enemy.





  • Ministry of Health:
    • Emu Hojo: Kiriya is interested in Emu because of his gaming skill and personality. From all the Gamer Riders, Emu is the most trusted person to work together with despite Kiriya always lying to Emu which mostly for Emu's own benefit. In his final breath, Emu was the one who Kiriya entrusted his Rider equipment before succumbing to his injuries.
    • Hiiro Kagami: Kiriya has a hard time getting close with Hiiro as Hiiro never believed in Kiriya due to his lies. This is shown when Hiiro states that Kiriya's friend, Jungo is not a victim on Zero day, but from a mere accident. Until when Kuroto reveals himself as Kamen Rider Genm, Hiiro finally believes what Kiriya had been trying to warn the Riders what he saw before.
    • Taiga Hanaya: Kiriya viewed Taiga as a dangerous person to be approached and hardly asked for his co-operation. Taiga is the only Gamer Driver user that Kiriya never get close with.
  • Genm Co-Op:
    • Kuroto Dan: Kiriya at first tried to make use of Kuroto to discover the truth behind Bugster invasion, especially the Zero Day. However, after learning the truth of Kuroto as Genm, he becomes Kiriya's number one nemesis. This hatred is further enhanced after Dan tricked everyone to believe that Genm is Parad. Despite being enemies, Dan claims he created the Game Driver and Rider Gashats to find out how the Bugsters enter the real world, not unlike Kiriya's own goal of searching for the truth behind the Bugsters. Unfortunately, Kiriya and the other three doctor Riders are too late to notice and stop Kuroto's true plan to gather more battle data to create the Dangerous Zombie Gashat. Ironically, Kuroto ultimately kills Kiriya, and stole his Gashacon Sparrow and the Giri Giri Chambara Gashat.

Behind the ScenesEdit


Kiriya Kujo is portrayed by Hayato Onozuka (小野塚 勇人 Onozuka Hayato). As Kamen Rider Lazer, his suit actor is Jiro Uchikawa (内川 仁朗 Uchikawa Jirō) in Level 1. His Level 2 form is based on a Honda CRF250L which is the same model as Machine Ghostriker. His suit actor from Chambara Bike Gamer Level 3 onwards is Satoshi Fujita (藤田 慧 Fujita Satoshi)[2].


  • Lazer is the first Kamen Rider to also be a Rider Machine.
    • He is also the second Rider to be able to transform into a bike after Accel.
    • Being a motorcycle that becomes a humanoid figure, he is also similar to the Auto Vajin.
  • His name is a play on the word "Racer" (レーサー Rēsā), quite fitting with his Racing Video Game motif.
    • His name also sounds similar to Razer, an American gaming hardware manufacturer.
  • As revealed in the Ex-Aid character book, Kiriya is 27 years old, making him the second oldest of the Gamer Riders.
  • Unlike other Ex-Aid Riders who pick up or gesture their Rider profile pics by hand while they transform, Kiriya kicks the profile pic instead.
  • Lazer has a samurai motif in Chambara Bike Gamer Level 3.
    • Also, him using a bladed bow as his weapon in this form is very similar to the New Generation Riders from Kamen Rider Gaim.
    • Lazer's headdress in Chambara Bike Gamer Level 3 is similar to Kamen Rider Agito. Both have a Dragon motif and are colored Gold.
    • Lazer Chambara Bike Gamer Level 3 also bears a slight resemblance to Kamen Rider Ghost's Grateful Damashii form.
  • Lazer is the only Rider in series whose Rider Gauge is still visible in Chambara Bike Gamer Level 3.
    • While in this form, Lazer has a second Rider Gauge on his shoulders, left over from his Level 2 form. Whether it functions or not in this form has not been determined.
  • Kiriya is also similar to Urataros from Kamen Rider Den-O due to their truth twisting tendencies. Unlike Urataros, whose lies convinces the Primary Rider, Kiriya is subjected to being called out even by Emu.
  • Kiriya is the only rider in the series who's main weapon took the longest to reveal itself.
  • Kiriya's death is currently the earliest out of the Neo Heisei era, which is even earlier than Kamen Rider Kurokage from Kamen Rider Gaim, who survived two more episodes than him.
    • Ironically, Kiriya died in a Christmas episode of a Rider series, which these episodes are usually jolly and easy-going from the start to the end.
  • Lazer's highest level form before his death was a Level 5 form, with his transformation catchphrase being "5th Gear". This is a possible reference to the fact that most motorcycles can only go up to fifth gear as maximum.
