―Accel's proclamation after a Maximum Drive as Accel Trial[src]

Ryu Terui (照井 竜, Terui Ryū) is Kamen Rider Accel (仮面ライダーアクセル, Kamen Raidā Akuseru). He receives his Acceldriver from Shroud.



He is a Superintendent appointed to the Futo Police Department's Paranormal Crime Investigation Division (超常犯罪捜査課, Chōjō Hanzai Sōsaka), and is Mikio Jinno and Shun Makura's superior. Prior to arriving in Futo, Ryu lost his family; his father, his mother, and his younger sister when a Dopant froze them solid. They shattered at Ryu's touch, killing them. In his final moments, Ryu's father warned him to beware the "Man with the W Memory". Ryu, however, goes the opposite direction and is driven for revenge with the aid of the mysterious Shroud. Due to place being the source of Memories, he developed a hatred of Futo and saw it as a gathering place of all kinds of scum.

Ryu received his heavy Engineblade from Shroud early on. He spies on the Narumi Detective Office using his Beetle Phone while he waits for his Driver to be completed. Soon after, a new crime wave starts, eerily similar to his parents' death. Thinking he has finally found his families' murderer, he steps out of hiding, revealing that he has been spying on the Office. He then gets his Driver and transforms into Kamen Rider Accel for the first time. However, Ryu goes overboard with the case, almost killing an innocent person he believed to be the Dopant. It turns out at the end of the case that the Dopant was Iceage Dopant, and the W Dopant was still at large, putting things in perspective for Ryu.

Though he and Shotaro Hidari clash at first, Ryu becomes an ally to the Narumi Detective Office when it comes to investigating the Dopant crime wave, as well as picking up some of Shotaro's habits in dealing with Dopants even after losing it upon finally finding his family's killer: the Weather Dopant, Dr. Shinkuro Isaka. After obtaining the Trial Memory from Shroud and learning to use it, Ryu is able to finally take his revenge on the Weather Dopant, using the Trial Maximum Drive to destroy his Gaia Memory, after which Isaka dissolved as a result of his long-term abuse of Gaia Memories.

After Isaka's death, Ryu becomes more open to the others and continues his role as a Kamen Rider to fight off the Dopant crime wave prior to learning that it was Shroud who gave Isaka the Weather Memory, though she had no idea that his family would suffer as a result. Furthermore, Ryu learns he has a unique physiology, enabling him to withstand the intense power of certain Gaia Memories and was selected by Shroud because he can resist the Terror Dopant's Terror Field. Because of this, Shroud wants him to assume Shotaro's place as Double using his hatred to enable Double to reach full power. However, Ryu has shown Shroud that he can fight with compassion and does not need to be Double to fight. Furthermore, after Philip's disappearance after Jun Kazu's defeat, Ryu had grown to love Futo with a desire to protect it, overall a complete turnabout from his initial personality.

Although he eventually rejected her advances to stay professional, he eventually started a romantic relationship with landlady/head of the Narumi Detective Office Akiko Narumi. Giving her the affectionate nickname "Chief" (署長, Shōchō) to reference her status at the Office and to give her authority, which she found cute. During the events of W Forever, Akiko tells him the story of how people watch the Futo Fireworks and fall in love, and she wants someone to watch it. So, just before he and Shotaro go to fight NEVER, he promises he will watch them with her. He fulfills his promise, and they fall in love.

In his Rider form, Ryu tends to say "Now, let's break away!" (さあ、振り切るぜ!, Saa, furikiru ze!) whenever he assumes his Rider forms and states "Despair awaits you (all) at the finish!" (絶望がお前(たち)のゴールだ!, Zetsubō ga omae (-tachi) no gōru da!, as Accel) and "[0.1-9.9] seconds, that is the time left until your despair!" (○○秒、それがお前の絶望までのタイムだ!, [0.1-9.9]-byō, sore ga omae no zetsubō made no taimu'da!, as Accel Trial) upon executing a Maximum Drive attack. The words on the back of his jacket read "spiritual state of nothingness makes even fire itself cool" which is a phrase derived from Buddhist philosophy.

"Don't ask me questions!!"
―Ryu's reply whenever being given a question[src]

First introduced, Ryu is a very cold person and a rider who seeks vengeance against the one who killed his family the user W memory Dopant which later revealed to be Shinkuro Isaka the Weather Dopant. He also at first not a city loving person and cares little about criminals, at one point almost killing the wrong Dopant with the same freezing ability as Weather, thanks to the guidance from Shroud. However, his time with Shotaro, Phillip and Akiko melt his cold heart and he slowly becomes a friendly person even to the point that he became engaged and later married Akiko.

As a person who then not out for revenge, his personality also can be shown becoming funny in certain situations, such as running away from being asked by Akiko to do a kissing scene for a movie and he forced himself to kiss anyone in the end (with Shotaro being a victim of his obsession to perfect his kissing). In Movie War Core DC version, he was terrified a bit when Akiko develops a "Kamen Rider allergy" (hating Kamen Riders) by stating "The goal of the wedding is despair" and laughed like a maniac for a bit, shocking Philip and Shotaro. He also convinced and vowed himself to no longer kill any criminal since his vengeance was fulfilled thanks to Akiko during Commander Dopant the vigilante in Kamen Rider Accel V-Cinema. As a father, which is shown in Kamen Rider Drive V-Cinema Chaser Saga, he is a very loving to his daughter. Despite this however, he still composed himself to be a cold and serious officer when he was working and not with his family.

He has an odd habit of objecting to being asked a question.

Accel Trial (アクセルトライアル, Akuseru Toraiaru) is the first evolved form of Kamen Rider Accel. It is significantly faster than Accel's normal form, but it sports weaker armor and overall power. It is more than enough to make up for its weakness by being able to punch and kick at blinding speeds, as well as increasing his overall movement speed (running, dodging, etc.) to a great degree. Once the Maximum Drive is initiated, Accel can only be used for another 10 seconds before being forcibly reverted back to human form, but the transformation is retained if the Trial Maximum Drive is successful before the 10 seconds are up.

AccelBooster (アクセルブースター, Akuseru Būsutā) is a second evolved form of Kamen Rider Accel that appears in Accel's version of the Kamen Rider W Returns DVD releases. This yellow-colored form of Accel uses the Gaia Memory Enhancing Adapter stolen from the Commander Dopant, which is attached over the top of the Accel Memory to increase its power output threefold.

AccelBooster's most notable feature is its additional armoring compared to Accel Trial, which hides a plethora of jet boosters enabling Accel to fly with great mobility, leaving large contrails of fire due to the tripled thermal energy output.

Like Accel's other forms, it can utilize the Engineblade.

This form's finisher is the Booster Slasher (ブースタースラシャー, Būsutā Surasshā): After inserting the Engine Memory in the Engineblade, Accel projects a large golden energy blade to slice through the target.

CycloneAccelXtreme (サイクロンアクセルエクストリーム, Saikuron Akuseru Ekusutorīmu) is a hypothetical form of Kamen Rider Double described by Shroud as being the ultimate form, with the change being that Ryu Terui becomes one with Philip instead of Shotaro, as their physiology make them immune to the psychological attacks of the Old and Terror Dopants.

However this form was never utilized in the series as Ryu decides not to fight as part of this form while showing Shroud that they can fight with compassion rather than hatred.

This form is exclusive to W Episode 43

Accel Trial Ridewatch (アクセルトライアルライドウォッチ, Akuseru Toraiaru Raidowotchi): Based on Kamen Rider Accel Trial, this Ridewatch would provide access to the Accel TrialArmor. It is dated 2009.




  • Narumi Detective Office
    • Phillip and Shotaro Hidari: At first they shared a cold rivalry because of different principle, especially Shotaro as Ryu is more hard boiled than he is. Being closer to often also what changed Ryu from being a cold into a heart warming and best friends for Double rider. Ryu often to come and share coffee with them, which at first ticked off Shotaro as he was told that his coffee is awful.
    • Akiko Narumi: He firstly saw Akiko nothing but a chief officer and didn't have any feeling towards her. But her childlike attitude soon warmed Ryu and led him to be her couple.
  • Futo Police Department
    • Mikio Jinno and Shun Makura: Both of them are Ryu's trusted underling after Ryu was transferred to work together with them
  • Shinnosuke Tomari and Go Shijima: Both of them came to know each other during the Beast-Roidmude Dopant investigation. Ryu immediately know that Shinnosuke and Go are Kamen Riders because they aren't panicking and composed to see monsters and preparing to fight back instead.


Behind the Scenes


Ryu Terui is portrayed by Minehiro Kinomoto (木ノ本 嶺浩, Kinomoto Minehiro). In Kamen Rider × Super Sentai: Super Hero Taisen, Kamen Rider Accel is voiced by Kōji Yusa (遊佐 浩二, Yusa Kōji), who voices Urataros in Kamen Rider Den-O. As Kamen Rider Accel, his suit actor was Eitoku (永徳).

Concept Art


  • His Rider name comes from the English word "accelerate".
  • Ryu is the first secondary Rider to make his debut in a movie instead of an episode of his series.
  • As Accel, Terui is the only Rider in Kamen Rider W with a suit not recycled from Double's design, as seen with Skull, Eternal and Joker.
  • He is the first rider who can change into a bike, the second one is Lazer.
  • He is the first and only Secondary Rider to have his own opening sequence (much similar to his counterpart's) but its theme song is Leave all Behind. It only appears in Kamen Rider W Returns: Kamen Rider Accel, in which Terui is the protagonist in the movie.
  • Strangely, Booster is used as a regular form change rather than an Ultimate attack despite being his strongest form in the Battride War video games.
  • Ryu's backstory is an homage to Shiro Kazami (Kamen Rider V3), as both of them lost their parents and younger sister to evil and initially fought for revenge before becoming more noble individuals thanks to their interaction with other Riders (the Double Riders and Kamen Rider Double respectively).
  • An in-joke reference to Ryu appears in Movie War Full Throttle, as a combination of the names of two construction companies working with the Zawame City Restoration Bureau, "Ryus O Kougyo" (lit. Ryus O Industrial Enterprise) and "Terui Tsuchi Kenchiku" (照井土建築 lit. Terui Building).
  • In the Futo Tantei manga, Accel is capable of deploying either of his wheels without turning into BikeForm. His rear wheel can be used to propel himself up the side of buildings and his front wheel on his back can be used for surprise counterattacks by springing up and then strafing the opponent if they are above him.
