Ryu Terui

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

History
He is a Superintendent appointed to the Futo Police Department's Paranormal Crime Investigation Division (超常犯罪捜査課), 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. Because it is the source of Memories, he developed a hatred of Futo and saw it as a gathering place of all kinds of scum.

Ryu Terui first made a cameo appearance at the end of Kamen Rider × Kamen Rider W & Decade: Movie War 2010 proclaiming that Kamen Rider Double is not the only Kamen Rider in Futo City any more.

Ryu received his heavy Engine Blade from Shroud early on. He spies on the Narumi Detective Agency 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 Agency. 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 Ice Age, 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 Agency 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 agency Akiko Narumi. Giving her the affectionate nickname "Chief" (署長) to reference her status at the Agency 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 Fuuto 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!) 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!) 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！) 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.

Movie War Core
In Movie War Core, Akiko tries to stop him from being a Kamen Rider, saying it was getting in the way of their life (and their wedding day), and causing them too much pain. However, he says he is a Rider to protect her. That, combined with what she saw through the Memory Memory about her father, convinces her to allow him to keep his Driver and Memories.

OOO, Den-O, All Riders: Let's Go Kamen Riders
Kamen Rider Accel was part of a group of reinforcement riders led by Akira Date/Kamen Rider Birth to aid the primary riders in defeating the Rock Great Leader. All the Kamen Riders got on their bikes, with Accel assuming his Bike Form, and performed the All Rider Break attack which destroyed the Great Leader.

Super Hero Taisen
Accel was among the Kamen Riders caught up in the 'Super Hero Taisen' incident. He was presumably sent to the dimensional rift, under the pretense of being defeated, by Captain Marvelous while he was apparently hunting the Riders. When his and Tsukasa's ruse was revealed, Accel and the other Riders appeared through the dimensional wall. Accel then fought alongside all the other Kamen Riders and Super Sentai against Dai-Shocker and Dai-Zangyack's Shocker-Zangyack Alliance. During the final battle, he is seen in the background with Shotaro and Philip and the Magirangers fighting Doukoku Chimatsuri. Also, in one of the movie trailers, he is seen with Shotaro and Philip fighting Weather Dopant, Cockroach Dopant, Spider Dopant, and Black Cross King from Goranger. However, since this fight scene was never shown in the movie, the results of the fight remains unknown.

Movie War Ultimatum
Ryu returned along with Shotaro and Philip also with Eiji and Goto in Movie Wars Ultimatum by Kamen Rider Wizard's summon ring which can summon any Kamen Rider. In Ultimatum, Ryu changed into Accel Bike Form that Kamen Rider Nadeshiko uses.

Super Hero Taisen Otsu
Ryu as Kamen Rider Accel was asking about his doubt on Electro Wave Tackle. In the end, he alongside Space Sheriff Gavan G, Kamen Rider Double, and DekaRed were stomped by Alien Baltan.

Kamen Rider Drive
Ryu halted Shinnosuke and Go to capture a robber who had his identity copied by Roidmude 051 because he won't allow any police officer to interrupt the crime investigation in Futo City without permission, especially the robber who was also involved in Gaia Memories as he shows the Beast Gaia Memory. He immediately notices that Shinnosuke is a Kamen Rider after he had been called by Krim. Before Shinnosuke and Go were about to save Chase, the robber started to flee and resist arrest, revealed himself to be Roidmude 077, and stole the Beast Gaia Memory. Shinnosuke and Go transformed right after Krim arrived to battle the Roidmude after it transforms into the Beast Dopant. Terui immediately joined the battle and revealed himself to be Kamen Rider Accel. After the destruction of Roidmude 077, Shinnosuke and Go bid farewell and Ryu wished them luck. It is also revealed that Terui has a daughter named Haruna when he was called by Akiko.

Personality
"Don't ask me questions!!"

- Ryu's reply whenever being given a question

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.
