Kiriya Kujo (九条 貴利矢) is a Medical examiner of Seito University Hospital. He obtained a Gamer Driver and the Bakusou Bike Gashat to become Kamen Rider Lazer (仮面ライダーレーザー).

Past
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.

Present
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.

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".

Seeing Snipe's debut make four players, he noted that it was about time to start the race.

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, Kamen Rider 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.

Personality
Kiriya is an easy-going man whose lighthearted attitude hides a sharp intellect and cunning nature. As such, he is a manipulative individual who will use dirty tactics to get what he wants, including deceit and sabotage. However, he does somewhat care for his patients as shown when he found out that Nishiwaki's sister was kidnapped by Graphite.
