"In the end, I have to entrust this to you, my son. I've failed as a father. Takumi...Have you grown taller again?"

―Shinobu's last words before dying.^[src]

Shinobu Katsuragi (葛城 忍, Katsuragi Shinobu) was a former member of INSET, the husband of Kyoka Katsuragi and the father of Takumi Katsuragi. He excommunicated himself in order to leave the remains of the Rider System to his son. However he was revealed to still be alive and working with Evolto. Shinobu possessed his own Build Driver, which he used to become a prototype version of Kamen Rider Build (仮面ライダービルド, Kamen Raidā Birudo). Secretly, he was actually developing a plan that would ultimately assist his son in his battle against Evolto.

History

Ten years prior, Shinobu was the leading member of the Mars exploration group, the Kiwami Project. However when he discovered that the Pandora Box housed members of the alien race known as the Blood Tribe and they had possessed the other members, he began to work on a series of weapons that would allow the users to defeat the alien tribes should they access their true forms. Shinobu had also discovered that the Blood Tribe had already made Earth their target some years prior in the form of Ryuga Banjo, so when Ryuga was a young child, Shinobu performed experiments on him to prepare him for the foreseeable future.

Sometime before the Sky Wall Disaster, Shinobu asked his son Takumi if he wanted to help his father prevent an alien invasion should the time come, with the boy replying with yes. When Soichi Isurugi, now possessed by Evolto touched the Pandora Box and caused the upbringing of the Sky Wall, the public went into tatters. During the commotion, Shinobu told his son that the only hope for Earth's future was Ryuga Banjou himself. Takumi asked his father why he was doing all this, and he replied that he was doing it for "love and peace" before running off.

Shinobu later received the aid of Reika Kine to help fake his death by smuggling himself out of Touto on the day he supposedly died. ^{[The Final Revolution]}. However it wasn't enough as Evolto would discover this and force Shinobu to work with him. With the new "cooperation", Shinobu created Lost Bottles, man-made Fullbottles that allows a human to transform into a Smash, although this made said human become more aggressive and easier to control and manipulate. Shinobu was also tasked with repairing Evolto's Evol-Driver under Project Evol. However, the Driver was taken and hidden away by his son Takumi, where Sento would later find it and reluctantly return it to Evolto. ^{[The Final Weapon: Evol]}

He later resurfaced at a Faust hideout in Hokuto where he sided with Evolto while searching for the Lost Bottles. ^{[The Truth of the Best Match]}

After revealing that his siding with Evolto was a trick to buy Sento Kiryu more time to foil his plan, he was later killed by the alien, redeeming himself when he gave Sento the data for both Build and Cross-Z and the ultimate Best Match, which would later be developed into the Cross-ZBuild Can. ^{[The Scientist of Hope]}

Legacy

Having performed a successful maintenance check on Kamen Rider Evol's system on the eve of Extra-terrestrial Lifeform Evolto vs. Kamen Riders, Nariaki Utsumi was deemed a worthy replacement for the late Katsuragi by Evolto. Soon after, Kazumi Sawatari took the elder Katsuragi's Build Driver, without Sento's approval, so he could utilize the full power of the Grease Blizzard Knuckle and North Blizzard Fullbottle for the coming battle at the Pandora Tower, at great risk to himself. ^{[An Oath to Be The One]}

Sento Kiryu and Takumi Katsuragi would often talk about their father, discussing whenever Shinobu's actions were right or wrong in order to justify their own.

New World

After the merging of the two worlds, Shinobu Katsuragi, along with his son Takumi, are alive in the New World, the latter now a separate individual from Sento. After Killbus re-activated Pandora's Box from the White Pandora Panel, Shinobu, his family, along with everyone who was previously exposed to Nebula Gas recovered their memories from the original World of Build.^{[Kamen Rider Build NEW WORLD: Kamen Rider Cross-Z]} After the incident, he worked alongside Gentoku Himuro and his father in creating this world's first Build Driver as a defensive measure for possible threats similar to the Blood Tribe, until it was stolen by one of Shinobu's previous scientists, Keiji Uraga, who also regained his memories from the other world. He also treats Sento as his "another son", presumably meaning their relationship remained close. ^{[Kamen Rider Build NEW WORLD: Kamen Rider Grease]}

Personality

Prior to Sky Wall Incident, Shinobu was a good-hearted man that cared for his son a lot. However, since he was the nearest to Pandora Box during the Sky Wall Incident, Shinobu's good nature was gone, him becoming a cold-hearted person with no qualms to do inhumane experiments as shown when he simply said that Misora could just die if Vernage was defeated. He also became nihilistic, as he openly admitted that he faked his death to his son and his wife, after siding with Evolto and supporting his plan to create a new world. However, Shinobu's affiliation with Evolto is actually a ruse, while under the pretense of allying himself with the latter was to give Sento enough time to delay his plans.

Forms

As the inventor and original intended user of the Build Driver, Shinobu Katsuragi can use the full potential of the Rider System. Since his Hazard Level is much higher, the stats reflected are much higher than when Sento Kiryu had used them. As Shinobu's Build Driver is a prototype based on the original schematics, it does not announce Best Matches.

• Rabbit
• Taka
• Ninjya
• Kaizoku

In any form that uses the Rabbit Fullbottle, Build is armed with the Rabbit Foot Shoes (ラビットフットシューズ, Rabitto Futto Shūzu) on his left leg for increased jumping, and can summon the Drill Crusher.

RabbitTank is considered to be the most well balanced; having a good amount of power and agility in all of his Ability Perimeters, thus making it Build's default form, despite it being capable of initiating transformation with any set of Build's Fullbottles. This is also Build's second fastest form.

In this Best Match form, Build is armed with the Tank Roller Shoes (タンクローラーシューズ, Tanku Rōrā Shūzu) on his right leg for kicking attacks, and can also act as a working tread to roll along on a flat foot.

This form's weapon is the Drill Crusher.

Shinobu lost access to this form after the Rabbit Fullbottle was stolen by Sento and transformed into the Golden Rabbit Fullbottle.

This form's finisher is the Vortex Finish (ボルテックフィニッシュ, Borutekku Finisshu), which has two variations:

• Build summons a white energy chart with the dotted line securing the enemy before leapingup and delivering a kick whilst riding the chart's line.
• Build performs a jumping roundhouse kick covered in red and blue energy.

While this Best Match has low stats compared to RabbitTank, this is made up for by the Solstall Wings on his back which grant him flight capabilities, as well as the utilization of the Gatling Fullbottle's Hawk Gatlinger that was designed for this particular Best Match.

Appearances: Build Episode 43-44

In any form that uses the Ninjya Fullbottle, Build wields the 4Koma Ninpoutou. It also grants Build the Onmitsu Scarf (オンミツスカーフ, Onmitsu Sukāfu) on the right side of his back.

This form grants Build well-balanced abilities akin of RabbitTank. Furthermore, it has increased kicking and punching power with the cost of jumping power and speed. The 4Koma Ninpoutou was designed for this particular Best Match. This is also Build's fourth fastest form.

As a Best Match, this form has several finishers:

It is a Touto Best Match, and is themed after a pirate and a train.

In this form, Build is armed with the Train Gauntlet (トレインガントレット, Torein Gantoretto) on his left arm for increased speed.

Behind the Scenes

Portrayal

Shinobu Katsuragi was portrayed by Joji Kokubo (小久保 丈二, Kokubo Jōji). As Kamen Rider Build, his suit actor is Kazuya Okada (岡田 和也, Okada Kazuya).

Notes

• As Build, Shinobu has demonstrated the ability to disguise his voice via voice modulation similar to that of the Transteam System, something that was not demonstrated by the primary user.
• Alternatively to RabbitTank, Shinobu has been observed to have a preference for NinninComic Form, which he has been shown to use a total of three times, more than any other Form available to him. Indeed, after he loses access to RabbitTank, it is this form that Shinobu resorts to. This is most likely due to his name having one of characters that spells "ninja."
• Shinobu is similar to Daigo Fukami, both have betrayed their own family in order to protect them in the shadows; in Daigo's case, he left his children to keep them away from the Gamma, Shinobu fakes his suicide and pretends to be an ally of Evolto to give Sento enough time to foil the evil alien's plan of destroying the world much like Kiriya Kujo did as Lazer Turbo in the previous series.
• As of his death, Shinobu has only used Best Matches that have suit-equipped weapons that aren't attached to the suit itself, namely, the Drill Crusher, Hawk Gatlinger, 4Koma Ninpoutou, Kaizoku Hassyar.
