Ryuga Banjo

This article is about a rider in Kamen Rider Build.

Template:Characterinfo Ryuga Banjou (万丈 龍我, Banjō Ryūga) is a 23-year-old ex-fighter who was wrongly imprisoned for the murder of a scientist named Takumi Katsuragi, who was involved with the Pandora Box. Abducted by Faust while in prison, Ryuga managed to escape with his humanity intact, which would lead him to join Sento Kiryu in uncovering the truth behind their shared experiences as Faust victims.

He would later use the Cross-Z Dragon given to him by Sento to become Kamen Rider Cross-Z (仮面ライダークローズ, Kamen Raidā Kurōzu), the secondary rider of Kamen Rider Build.

Character History

Ryuga was born in Yokohama, weighing 3.2 kg. As an adult, Ryuga became a professional fighter, eventually getting engaged to Kasumi Ogura. By the age of 22, Ryuga earned a lifelong ban from fighting for throwing a match; it is implied that he accepted a bribe in order to pay for the frail Kasumi's medical bills. To help his search for a new job, Kasumi directed Ryuga to Takumi Katsuragi, a researcher at the Touto Institute of Advanced Matter Physics, who was apparently looking for an assistant. However, when Ryuga came to Katsuragi's home to apply, he found the latter's corpse inside. Moments later, Touto's Guardians arrived and apprehended Ryuga. Framed for Katsuragi's murder, Ryuga was sentenced to ten years in prison.

While in prison, he was attacked by a prison guard working for Faust, who began experimenting on him to turn him into a Smash. Somehow, Ryuga managed to escape mid-experiment, retaining his memories and humanity, and retreated into the sewers.

Meeting Sento Kiryu

Ryuga was eventually found by Touto's Guardians, who attempted to recapture him. Ryuga managed to fend off the Guardians and escaped before he was apprehended by Sento Kiryu, who had tracked him upon noticing his Smash-like energy readings. Upon realizing that Ryuga had undergone a similar experience, Sento began interrogating Ryuga in hopes of uncovering his past, despite Ryuga's frustrated belligerence. The two were interrupted by Strong Smash, who attacked Ryuga. However, Ryuga was saved by Sento, who transformed into Kamen Rider Build and defeated the Smash. Ryuga recognized the Smash's human identity as one of his fellow victims, but was frustrated to find that the man had no memories of the experiments. The Touto government arrived soon after to retake Ryuga. Sento, believing in Ryuga's innocence, helped him escape.^{[That One with the Best Match]}

Burn Smash incident

Sento brought Ryuga to the basement lab of the nascita café, where the former had been living for the last year. After meeting Sento's accomplices, Souichi and Misora Isurugi, Ryuga explained the cirumstances that resulted in his arrest. However, the story was interrupted by Sawa Takigawa, a freelance journalist who had entered the base (due to Souichi and Sento's carelessness).

As a precaution, Ryuga was chained up in the lab, much to his chagrin. Misora took the time to explain the Fullbottle purification process to Ryuga, as well as Sento's job. Noticing Misora's smartphone, Ryuga goaded her into proving her ability to purify Smash energy. As planned, Misora left her smartphone where Ryuga could reach it, allowing him to contact Kasumi. However, much to his horror, Kasumi had been kidnapped by Faust as well. Given Kasumi's location by Night Rogue, Ryuga broke out of nascita and raced to save his fiancé. After another encounter with Guardians (which ended with being saved again by Build), Ryuga explained his motives to Sento, but choked him into unconsciousness to prevent him from getting involved.

When Ryuga finally arrived at the location, he learned that he was too late: Kasumi had already been transformed into the Burn Smash. Unable to see his beloved hurt, Ryuga begged Sento not to attack her when the latter arrived. The two were quickly overwhelmed by the Smash and Night Rogue, upon which the latter revealed the horrifying truth: Kasumi's body was too weak to be restored, and removing her Smash essense would be fatal. Realizing that Kasumi could not be saved, Ryuga begged Build to end her suffering. Sento was able to separate Kasumi's consciousness long enough for her and Ryuga to say their goodbyes. Left almost broken by grief, Ryuga would have let himself be captured again if not for Sento, who reminded him that it would all be for nothing if he got arrested again. Kasumi's Smash essence was purified into the Dragon Fullbottle, which Sento gave to Ryuga as a memento of his beloved. Soon after, Sawa arrived, having discovered the identity of the guard who attacked Ryuga: Masahiro Nabeshima.^{[The Innocent Runaway]}

Continuing the Search

After some searching, Ryuga managed to contact Nabeshima. Nabeshima revealed that his family was being threatened by Faust, upon which Ryuga offered to smuggle them out of Seito to safety in exchange for Nabeshima testifying for his innocence (not realizing this was a trap set up by Night Rogue). With Sawa's help, Ryuga snuck to Seito. Upon retrieving Nabeshima's wife and daughter, Ryuga and Sawa were attacked by hijacked Guardians, barely escaping with their lives. Ryuga arrived in Touto to aid Build in taking down Nabeshima, who had been subjected to two Smash transformations by Faust. While Nabeshima was returned to his human form, the experiments wiped his memory clean, leaving him unable to recognize his daughter, let alone testify for Ryuga.

The next lead came in the form of Tatsuya Kishida, who was roommates (as well as bandmates) with Sento before the latter was captured.

Personality

Ryuga is a hot-blooded and impulsive man, tending to lash out quickly. While nowhere near as intelligent as Sento, Ryuga prefers to confront problems directly using his fists and doesn't want to involve other people in his own problems. Also, unlike Sento, he does not overthink things, preferring to use common sense, as shown when he was easily able to guess two Best Matches on his own. He is shown to easily get startled, a good example is when the bell goes off indicating a Fullbottle is ready.

Beneath his tough exterior is an honest, selfless and honorable individual. It is implied that the cheating that banned him from fighting was to get money for his fiancé's medical treatments.

Ryuga also have a friendly side, such as when he encourages Takehiko after Build removed Smash essence from him.

Behind the Scenes

Portrayal

Ryuga is portrayed by Eiji Akaso (赤楚 衛二, Akaso Eiji), who previously portrayed Hiroki Nagase in Kamen Rider Amazons Season 2.

Etymology

The kanji "Ryu" (龍, "Ryu") used to spell his first name means "Dragon".

Notes

• Ryuga's characteristics are near polar-opposites of Sento Kiryu, as Ryuga possesses high-stamina prowess that can fend off inhumane monsters while lacking a standard-level intellect, while Sento possess a genius-level intellect to create gadgets as part of his force but doesn't have Ryuga's high-level stamina or strength.
  • The duo often make some Manzai  (漫才,まんざい, Manzai ) conversations, with Sento serving as the funny man (ボケ, boke) and Ryuga as the straight man (突っ込み, tsukkomi), as a way to reflect the characteristics.
• Kamen Rider Cross-Z's name is an anomaly. The pronunciation and spelling, Kurōzu (クローズ, Kurōzu), could refer to "Close", "Claws", "Crows", or "Clothes", but when it was revealed, it was commonly agreed that it meant "Close" or "Claws". When the Cross-Z Dragon appeared in the series, a profile image for it on the TV Asahi website was found to be titled "cross.png", insinuating that Kamen Rider Cross-Z's name would be Cross. Eventually, a pair of children's boxers produced by Bandai revealed the spelling Cross-Z.
• Kamen Rider Cross-Z's suit is modified from Kamen Rider Build's Dragon Half Body. This mechanism is used to have Cross-Z to compatible with the Build Up function.
• Ryuga has some similarities to the previous character that his actor portrayed prior to Kamen Rider Build, especially in terms on how they first met their respective protagonists. Ryuga and Sento got off to a rocky start that is until the former decided to take refuge with him in order for Sento to figure out his lost memories. While Hiroki had a hard time in getting along with Chihiro at first; although he becomes more caring towards him as Amazons S2 progresses.
