Ryuga Banjou (万丈 龍我 Banjō Ryūga)[1] 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 uses 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.

As war breaks out between Hokuto and Touto, Ryuga takes the Sclash Driver against Sento's objections to become Kamen Rider Cross-Z Charge (仮面ライダークローズチャージ Kamen Raidā Kurōzu Chāji).

Character History

Baby Banjo

Sento interrupts Ryuga's recollection of his birth.

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 the corpse of "Katsuragi" inside. Moments later, Touto's Guardians arrived and apprehended Ryuga. It would be revealed that it was Soichi Isurugi who called Ryuga the murderer, which would give Ryuga a ten-year sentence in prison.

While in prison, he was attacked by a prison guard working for Faust, who injected him with Nebula Gas. However, Ryuga's naturally high Hazard Level allowed him to escape mid-experiment with his memories and humanity intact. After fighting off the Faust scientists, he retreated to 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, and removing her Smash element 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 lost his memory.

Becoming Cross-Z

Learning Sento Kiryu's True Identity

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, especially 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 fiancée's medical treatments. Ryuga also has a friendly side, such as when he encourages Takehiko after Build removed the Smash essence from him.

Ryuga is also shown to have a selfless side, as when he attacked Blood Stalk out of anger for the sake of both Sento and Misora, completely disregarding the fact that Stalk framed him.

Ryuga's personality began to alter upon his constant usage of the Sclash Driver, much to Sento's warnings of the side effects. He become more aggressive and desperate to become Stronger. However his honor still stood as he revealed that he didn't listen to Sento because he's want to pay back his debt to him, therefore he wanted to become Sento Strength for his own sake.

Powers and Abilities

  • Hand-to-Hand Combat: Ryuga is a skilled fighter, having fought professionally before getting a lifelong ban.
  • High Hazard Level: Initially, Ryuga's Hazard Level is above 2.0, allowing him to retain his humanity after exposure to Nebula Gas while still gaining physiological powers from it. According to Blood Stalk, while fighting, Ryuga can raise his Hazard Level, having raised it as far as 2.7. Originally, in a fight against the former, his Hazard Level was 3.0, which is high enough to use the Build Driver. Recently, however, his continued fighting as Cross-Z raised his Hazard Level to 4.0, enabling him to use the Sclash Driver.
    • Superhuman Strength: Ryuga has displayed enhanced strength: he was able to fight off numerous Guardians on his own, and break metal chains with his bare hands.
    • Smash Energy Signature: Since he is exposed with the Nebula Gas, Ryuga gives off an energy signature similar to a Smash, which alerted Sento to his location.
  • Fullbottle Augmentation: By using a Fullbottle in his hand without transforming, Ryuga can gain abilities based on said Fullbottle's traits:
    • Dragon: Ryuga's punches give off powerful shockwaves. Notably, his strong synchronization with the Dragon Fullbottle causes his power to increase with each use. Currently, it gets to the point where Ryuga is strong enough to even defeat a Hazard Smash while as a human.

Weakness

  • Short Temper: Despite being a capable fighter, Ryuga is shown to be easily provoked in most situations. When combined with the priority to prove his innocence, it sometimes caused a major sidetrack in Build's battles against Smash (such as transforming Tatsuya back into Press Smash just to locate Faust's base) without even forming the next phase of his plans.

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. As Kamen Rider Cross-Z, his suit actor is Eitoku (永徳 Eitoku), who returned in portraying Secondary Riders after Baron.

Etymology

The kanji used to spell his first name can poetically mean "I'm a Dragon" (竜が Ryū ga).

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) 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.
Cross-Z Armorless

Cross-Z mid-transformation, appearing like a variant of Build

  • Kamen Rider Cross-Z's design is that of Build's Dragon Halfbody, made into a full Rider design with distinct armor added on top. Even his arms and legs are asymmetrical, as orange flames are added only to the limbs that aren't shared with Build.
  • 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.
  • Cross-Z is the second secondary rider since Kaito Kumon and the other Gaim Riders to switch belts and upgrading his form (Cross-Z Charge).
    • His Rider designation's extension is similar to how Takatora Kureshima became Zangetsu Shin with the upgraded belt, except Ryuga's upgrade came directly from his original form, while the basis for the Lockseed differed from the upgrade.
  • Cross-Z is the first secondary rider to have a dragon motif.
  • Cross-Z's Dragonic Finish is performed almost exactly the same as Kamen Rider Ryuga's Final Vent attack from Kamen Rider Ryuki (and less exactly like Ryuki's), a kick propelled straight forward by a large serpent dragon's blue fire breath. The only difference is whilst Ryuga uses the standard Rider Kick, Cross-Z uses a roundhouse Rider Kick like the one used by Kamen Rider Gatack.
  • Interestingly, Cross-Z and Gatack also have a few things in common:
    • They have asked the primary rider of their respective series (Kabuto and Build) to defeat the respective series kaiju that is dear to them (Burn Smash for Cross-Z and Bellcricetus Worm for Gatack)
    • They use the same belt as the primary rider of their respective series to transform (Build Driver and Rider Belt) with the difference being either the color and/or the transformation trinkets.
  • Ryuga's upgraded form using the Sclash Driver is unique in two aspects:
    • The form's head armor is essentially just liquid formed over a round shell, yet has roughly the same sculpt of the previous form, unlike previous upgrades where the Rider's helmet is altered or designed to include new elements.
    • It is the only upgrade form debuting in the main series which lacks prerequisites to access (Ryuga already possessed both a necessary Hazard Level, and the components from Sento building the Driver/creating the Sclashjelly), while still being able to use the same system as the main Rider. The new system used hence functions as an upgrade.
