Soichi Isurugi (石動 惣一 , Isurugi Sōichi) is the father of Misora Isurugi, owner of Nascita, and former astronaut who was possessed by the alien Evolto (エボルト, Eboruto) and transformed into Blood Stalk (ブラッドスターク, Buraddo Sutāku) and later Kamen Rider Evol (仮面ライダーエボル, Kamen Raidā Eboru). After Evolto's defeat and the creation of the new world, Soichi returned to his normal life without any of his previous memories.
History[]
Background[]
Soichi Isurugi is the father of Misora Isurugi and a former astronaut working with the Kiwami Project. Ten years ago, Soichi was on a manned exploration on Mars and discovering the Pandora Box in the ruins. However, as he touched the relic, the extraterrestrial lifeform Evolto would take over his body and returned to Earth. To create the sixty Fullbottles from the Pandora Box based on Soichi memories, Evolto asks the man for thirty things he liked to create Biotic Bottles and odd objects to create the Abiotic Bottles.
Upon arriving on Earth, Evolto used Soichi's body to trigger the Pandora Box and raise the Pandora Tower. However, his attempt failed as Vernage also found her way to Earth and took hold of Misora's body to remove the essence of the Fullbottles, causing the Sky Wall to rise instead. After being medically diagnosed as being "psychologically insane", Soichi was arrested and placed in a mental hospital, in which Misora was also admitted into as well. Several months later, Evolto escaped from the mental hospital and took residence in Touto where he opened up a café called Nascita there.
Evolto continued to possess Soichi's body as he led Faust as Blood Stalk and posed as Sento Kiryu's mentor figure as he indoctrinated him to become Kamen Rider Build.
Release from Evolto[]
Sometime after Vernage made her presence, Soichi's consciousness was able to reemerge and trying to resist Evolto's hold over him. Soichi questioned Evolto's intentions before Evolto regained his control. He told Soichi not to do that again and to keep silent and watch as he transformed into Blood Stalk.
Soichi left unconscious.
When Evolto initiated "Phase 2" of his ultimate plan and possessed Ryuga Banjo, he had finally separate from Soichi Isurugi's body. Soichi was left unconscious and taken to a hospital by Sawa Takigawa and Kazumi Sawatari. After the Evol-Trigger was repaired and regained his Black Hole form, Evolto would later assume Soichi's appearance.
New World[]
Soichi confusing Sento with Taro Satou.
After Sento defeats Evolto for good, the new world had been successfully created. This new world version of Soichi now works at Nascita with his daughter. He's shown to actually be able to make a good cup of coffee, as proven by Sento, unlike Evolto's possession of him in the old world. Soichi mistakes Sento for Taro Satou, of the band Tsunagizu, and asks for his autograph. [The Tomorrow Build Will Create]
During the events of Build NEW WORLD: Kamen Rider Cross-Z, Misora mentions that her memories from the old world have returned but Soichi doesn't remember anything about the old world, since he was not being experimented on with Nebula Gas and his abilities was a result of Evolto taking over his body.
Personality[]
Ten years ago, Soichi was said to be a kind and caring person, as shown when he reads to his young daughter Misora Isurugi, remembering all the things she liked. According to Sawa's investigation of him, Soichi was also described to be someone who was friendly and had a strong sense of justice. However when he returned to Earth with Pandora's Box, he was possessed by Evolto. During his possession, Soichi was constantly struggling for control of his own body, although his attempts were in vain.
It's also implied that while Evolto is possessing Soichi, he would emulate Soichi's original personality.

Similar to Night Rogue, Blood Stalk accesses his main form with the Transteam Gun and the Cobra Fullbottle. Unlike Riders and other Transteam/Kaiser system users, Evolto is almost always seen transformed into Blood Stalk after his identity has been revealed to Sento and the others at Nascita.
His stats are not only stronger than most of Build's forms, but also surpass Night Rogue's with only speed being slightly lower than his. Stalk also possesses numerous abilities built into his suit. On each wrist, he has extendable venomous tendrils that can shoot out and stab victims, injecting them with venom capable of either paralyzing, killing, or even disintegrating them. He can also create an energy cobra projection through his suit to attack or capture targets. It has been proven that Evolto is extremely proficient with the Blood Stalk arsenal and its abilities granted to him; his skill with the Transteam System, coupled with his enhanced durability, has allowed him to survive multiple skirmishes with Build and Cross-Z, and defeat Night Rogue in a duel.
The true purpose of the Blood Stalk system is to encourage the rise of Hazard Levels in Riders. Thus, he is shown capable of accepting far greater punishments than either Build or Cross-Z. Instead of showing pain or discomfort, Stalk is otherwise enjoying the beatings so long that his opponent's Hazard Level rises. In order to facilitate this, Blood Stalk can measure the current hazard level of Kamen Riders/Smash by simply touching them.
Stalk states that this form is merely temporary, as he uses powers acquired from Mars to stay toe to toe with enemies that are supposed to be stronger than what the Transteam System can put out. This is is shown when Stalk was able to fight on par with Build's RabbitTank Sparkling form while Night Rogue was easily defeated by it.
Blood Stalk also has several non-combat abilities. As mentioned by Takumi himself, Stalk's equipment has the ability to change its user's voice tone freely to hide his identity. It is later revealed that the alternate voice is that of Evolto. [The Truth of the Pandora Box]. Stalk is also able to activate the Guardians’ true programming as sleeper agents of Faust by snapping his fingers. When in need of a quick escape, he can escape any situation by becoming a cloud of red smoke and flowing away.

Cobra Form (コブラフォーム, Kobura Fōmu) is Evol's primary and default form accessed with the Cobra and Rider Evolbottles. Evolto labels this form as "Phase 1" (フェーズ1, Fēzu Wan).
As Evol, Evolto possesses tremendous power, as the Evol-Driver allows him to tap on the full power of the Pandora Box. His specs blow far past Grease, Rogue, and even Cross-Z Magma by a small margin. He also surpasses Build's RabbitRabbit and TankTank forms, though he loses to RabbitRabbit by maximum jump height and running speed, and TankTank by maximum kicking power.
Despite these small disadvantages, he still possesses abilities that are almost impossible to counteract, including teleportation and generating energy in his hand to perform an energy blast. He is also able to attack in extremely high speeds and block attacks quite easily, as shown during his first fight with Rogue.
His Evol Cobra Head (ＥＶＯ-コブラヘッド, Ebo Kobura Heddo) contains the Xeno Head Armor (ゼノヘッドアーマー, Zeno Heddo Āmā) which strengthens its durability within each Phase. Between his EVO Twin Eye Cobra (EVOツインアイコブラ, Ebo Ai Kobura) lies the Master Planisphere (マスタープラニスフィア, Masutā Puranisufia), a device that allows him to determine which celestial body is his next target and formulate the suitable method of destroying it.[1]
In this form, Evol's armor parts are:[2]
- EVO Cobra Shoulder (EVOコブラショルダー, Ebo Kobura Shorudā): A pair of shoulder armor that allows him to improve attack accuracy. Each has a built-in miniature plant that secretes toxic gases as enhancers of the user's ability.
- Menace Rush Arms (メナスラッシュアーム, Menasu Rasshu Āmu): Evol's arms. Through an unknown substance that filled his suit, Evol's strength and speed are enhanced. By himself, Evol can manipulate a special aura that can move objects at will or detain his opponents.
- EVO Xeno Vader Gloves (EVOゼノベイダーグローブ, Ebo Zeno Beidā Gurōbu): Enhanced combat gloves that allows him to create strong punches by manipulating nearby space.
- Menace Rush Legs (メナスラッシュレッグ, Menasu Rasshu Reggu): Evol's leg units. Through an unknown substance that filled his suit, Evol's strength and speed are enhanced. By himself, Evol can manipulate a special aura that allows him to move objects or run at a tremendous speed.
- EVO Xeno Vader Shoes (EVOゼノベイダーシューズ, Ebo Zeno Beidā Shūzu): Evol's combat shoes. Each can perform kick attacks by manipulating nearby space.
- Xeno Chest Armor (ゼノチェストアーマー, Zeno Chesuto Āmā): Chhest armor which compresses and produces unknown substances within the Evolbottles. Said armor is stronger than any material on Earth and its durability increases within each Phase.
- Armilla Reactor (アーミラリアクター, Āmira Riakutā): An Armillary sphere-themed conversion furnace which converts the unknown substance within Evolbottles into strong destructive energy. By completing all Phases, it can demonstrate its true ability.
- EVO Omniverse Suit (EVOオムニバーススーツ, Ebo Omunibāsu Sūtsu): An enhanced battle suit that can emit blocking energy field, allowing Evol to protect himself from enemy attacks or carry out planetary destruction safely. It can also draw out the user's hidden ability and strengthen them based on the Phase.
- EVO Material (EVOマテリアル, Ebo Materiaru): Golden armor parts on Evol's body. They can amplify Evolto's special abilities, empower wave attacks, generate annihilation poisons and allow warp teleportation.
Carried over from from Blood Stalk, Evol wields the Transteam Gun and Steam Blade in this form. He is also able to wield any of Build's weapons if he inserts the corresponding Fullbottle into the Evol-Driver along with the Rider Evolbottle.
This form has three finishers:
- Evol Driver Finishers:
- Evoltic Finish (エボルテックフィニッシュ, Eborutekku Finisshu) This finisher has two variations:
- Rider Kick: Evol generates an energy star map beneath his feet that then transforms into a dark red and dark blue energy galaxy that flows into his right foot before delivering an explosive kick.
- Steam Shot (スチームショット, Suchīmu Shotto): Evol channels the powers of a Evolbottle/Fullbottle and performs a powerful steam blast attack.
