==Biography==
===Early Life===
When Yuto was a child, he moved to a small town to live with his grandmother following the death of his mother and was teased by the other children for being a city boy. He possessed an artifact called the Trump Stone, which made him a target of the Oni Brothers Goludora and Shilubara. Thus Deneb, Ryotaro, Kotaro and the rest of the DenLiner crew aid him and get the artifact to the past.
Unbeknownst to everybody, the DenLiner crew weren't aware that Yuto's true identity, referring the boy as "Yu". Deneb asks to form a contract with him, allowing him to gain a physical form. Yu's wish for the contract is for Deneb to see his contract holder, once more. After he is returned to his own time, Yu promises to meet Deneb again and tries once more to settle in his new home.
===Becoming Kamen Rider Zeronos===
Prior to the series, Yuto Sakurai encounters his future self, the older Yuto Sakurai of 2007, who revealed to him the situation relating to the Imagin. Provided with the Zeronos arsenal and Deneb, Yuto takes the ZeroLiner forward in time to May 20, 2007, where he makes himself known to Ryotaro Nogami after the Wolf Imagin is destroyed. He warns Ryotaro not to look for the mysterious man in the trenchcoat, the future Yuto Sakurai that Ryotaro knows as his sister's fiancé. Yuto also reveals that he is Kamen Rider Zeronos, chiding Ryotaro's flawed ideals as Den-O yet was unhinged when Ryotaro intended to keep fighting for what he believes in. Once he meets his near-future self, who abducts Ryotaro to prepare for an event known as the Climax Scene, Yuto begins to respect the boy chosen to be Den-O.
Yuto originally has ten Zeronos Cards, the items that allow him to become Zeronos, which are in turn are tied to the memories people have of the elder Sakurai. Each time a card is used up from a battle, the memories from normal people who knew Sakurai disappear as well. It is this reason that he tries not to become Zeronos very often, only doing so if it is necessary to help Den-O. After using up his second-to-last card in an attempt to save Deneb, only to learn it was a false alarm, Yuto is reluctant to use his final card until Airi is kidnapped by Fujishiro, one of her former suitors that has been possessed by the twin Anthopper Imagin. He uses his last card as Airi begins to remember him, making Fujishiro and Airi lose all memories of the Sakurai they knew. Unable to become Zeronos, Yuto is confronted by Sakurai himself, receiving another set of Zeronos Cards despite Deneb's protests. These new cards show that the older Sakurai is displaced from time and space during each transformation, as memories of him alone cannot power the cards. As Kai arrives, Kai sees fit to eliminate Yuto Sakurai, as he believes that Sakurai is the key to the Junction Point. Kai sends the female Snail Imagin to 1993 to kill Yuto before he could meet Sakurai, removing him from time.
However, the Zeronos Cards have created a time lag, allowing Yuto to return despite not being a Singularity Point like Ryotaro. He also uses red Zeronos Cards, which Ryotaro notices. Yuto tells him that the memories of the older Sakurai are no longer enough to support Zeronos' power, and now his memories in 2007 are being used as power to transform him into Zeronos Zero Form. Eventually, Kai starts to question his agenda and realizes that Yuto and his future self have been acting as a distraction from his true target: Airi, who is tied to the Junction Point. Once Ryotaro goes into the past, Yuto is forced to battle the numerous Imagin under Kai, fighting them and the Death Imagin to protect Airi until Ryotaro returns.
When Ryotaro does return, Yuto fights alongside him using the last card Deneb gave him, which severs his ties to his future self. After the battle is over, Yuto immediately returns to the ZeroLiner to find Deneb only to find nothing but the last meal Deneb prepared for him, which ironically has shiitake in it. Yuto willingly eats the meal as Deneb surprises him. Instead of comically beating him up as normal, Yuto instead hugs Deneb, crying tears of joy. After Yuto, Hana, and Ryotaro discuss their respective futures, Yuto gives Hana a pocket watch, which signifies a possible meeting in the future. Yuto and Deneb say their goodbyes to Ryotaro as the ZeroLiner departs into the time stream.
Later, Ryotaro finds Yuto having been investigating the crime lord Seiya Kuroki undercover and discovering his ties to Negataros. Yuto and Deneb manage to maintain his guise of being a villain in the ranks until Ryotaro's partner Suzuki gets himself caught by the evil organization. Attempting to save Suzuki, he gets caught in Negataros' trap to draw out the detectives pursuing him. In the ensuing battle, Yuto is revealed to be in possession of more regular Zeronos cards.

======
After Shocker alters the timeline, due to being a member of the Liner Crew, Yuto and Deneb survived the alteration, and they went out to find other Riders who resisted Shocker's reign to help them find other Rider friends whose memories were altered, brainwashed, and/or captured. Deneb went into hiding, while Yuto was joined by Drive after Kotaro Minami managed to restore the Shift Car using the Heisei Rider's original memories, Go Shijima, and last but not least is none other than Kyoichiro Kuroi, who was formerly Shocker's brainwashed Rider prior to sending him from 2015 to 1973, and now on the run from Shocker. While Shinnosuke Tomari needs some time to recover himself, he, Kyoichiro and Go encounters Sakuya Tachibana, and one of the other main Royal Card Kamen Riders, whereas Mutsuki Kamijou and Hajime Aikawa became members of Shocker, and Kazuma Kenzaki is initially held as a prisoner. Apparently, the rescue was all a ruse, as Tachibana and Kenzaki are actually evil all along, but they manage to defeat the Royal Riders, as they escape again. However, they are chased by Takumi Inui, who they thought was with Shocker until he revealed he was there to assassinate Kyoichiro. As Mach handled Faiz, Zeronos and Rider 3 escapes, but only to be ambushed again by the Shocker Riders, as Rider 3 sacrificed his life to save Zeronos since they were after Rider 3, but Rider 3 was captured and brainwashed again.
Though there's no hope left, as Yuto was caught by Shocker, with a brainwashed Kyoichiro with them, a recovered Shinnosuke arrived to challenge Shocker to a race, but on one condition is to hand over Yuto as a hostage, as Shocker also held a still alive Kiriko as a hostage too, Shinnosuke accepted. While Yuto and Kiriko are watching the race, they saw Shocker doing dirty work to make Rider 3 win, yet Drive was lucky enough by being reinforced by a revived BLACK RX Kotaro, Faiz, and Mach. When Rider 3 rejects Shinnosuke's empathy of being a winner means no cheating, led to a kid who watches the race supporting the Kamen Riders, as well as leading the civilians to do so, even the kids whom Kotaro saved defects from Shocker. After Rider 3 is freed from being brainwashed and remembered Shinnosuke's empathy, accepting his loss. However, Shocker doesn't want to accept their loss as the Great Leader put Rider 3 into a vessel in the form of Rider Robo, orders all Shocker members, including the Riders to kill the Kamen Riders and their civilian resistance. After he and Kiriko are untied by the three former Shocker kids, he is reinforced by Deneb and transformed into Zeronos Zero Form, later being aided by the fully recovered Royal Ace Kamen Riders, who shortly began to recover their original memories. Rider 3's remaining consciousness revived the original Double Riders into the future, with memories of the present era, managed to recover the Shocker Riders' memories and turned them back into Kamen Riders once again. Great Leader then went too far by erasing most of the Riders' existences, until Rider 3 himself managed to break himself free from Rider Robo's vessel, rendering the Great Leader powerless and unable to utilize a time alteration. As the battle is over, with the help of the Ninningers, but they lost one ally, Mach, the timeline is about to be restored, as Kyoichiro bids his Rider allies farewell as a Rider, and may see them on the other side as a normal human. Yuto is last seen with Deneb when he noticed of Deneb's suspicion in attempt to put a shitake into Yuto's meal.
===D-Video Special: Kamen Rider 4===
Taking place after the events of Taisen GP, Takumi and Yuto appear in the Drive Pit, alerting Shinnosuke to fight against Shocker. During their battle, Go appears and they all defeat the Shocker monsters. However, one hasn't been defeated and takes down Go with him. As Go dies in Kiriko's arms, time stops and a stopwatch is shown to count down to zero. Time loops back to when Takumi and Yuto appear in the Drive Pit, and the same events happen as before, but the noticeable part is when Shocker is shown to be stronger each loop. In order to find out what's happening, Yuto and Deneb use the ZeroLiner to go back to the point in which Go originally died. It's later revealed that the machine from Taisen GP is rebuilt, but this time, it's the Riders who are powering it. The aforementioned strength Shocker gets after each loop includes a new Kamen Rider, named Kamen Rider 4, who, unlike the Double Riders and Kamen Rider 3 before him, is completely cyborg, with no emotion and heart. Back in the Drive Pit, Shinnosuke assumes that Kiriko is the one powering the machine, due to her breaking down each time Go or Shinnosuke dies. In a new loop, the Riders (excluding Go) storm the Shocker headquarters. In response, they take Go and Kiriko hostage. Kiriko then proceeds to fall off the building that she and Go are on, as Shinnosuke cries out her name as time stops again, revealing it isn't Kiriko who is powering the machine. In reality, it is Takumi who is powering the machine, due to having to carry the burden of his fallen friends, with Naoya Kaido being the only one of his original friend group to still be around. Takumi lies on the same hill he laid on after defeating Smart Brain, where Yuto and the others find him, as he says that he'll die a second time for the loops to stop. Go decides to take a picture of the group so that Takumi could be remembered before he dies. The four Riders arrive at the Shocker headquarters, as they transform and fight the monsters, clearing a path for Takumi to find the machine. Yuto transforms into Zero Form, as Go transforms into Deadheat Mach, to defeat the Dark Riders resurrected by Shocker using their finishers. As Yuto and the others find Takumi, the Great Leader is revealed to have taken on the appearance of Takumi. He uses the Faiz Signal Bike to transform into Faiz, and prepares to use the Axel Watch to manually reset the time and enter another loop again. However, Takumi shoots the Watch, destroying the Great Leader, while also sacrificing himself. Time resets to normal as Shinnosuke is late to his day off with Kiriko and Go. He passes by Yuto along the way, in which Shinnosuke gives him the same picture that Go took before their fight. As Yuto sees the picture, he smiles, but it's shown that Takumi is nowhere to be found. It is revealed that none of them are shown to remember Takumi. Yuto gets on his bike and rides off.

==Personality==
Unlike Ryotaro, Yuto claims that protecting the flow of time is not the same thing as protecting people. He says that saving people is unnecessary if it means disrupting the flow of time even if it means sacrifices must be made to save the future. He holds a very spoiled personality, and often acts like a child when things do not go his way and putting lots of sugar in his coffee before actually tasting it, hence earning him the nickname by Urataros. Yuto is also the kind of figure who would use dishonest methods to get the job done, but has since abandoned this way of fighting. A running gag with Yuto is his hatred for shiitake mushrooms, going as far as a comic beating to make sure Deneb does not serve or buy any.
When possessed by Deneb, Yuto's hair grows out past shoulder length with two locks of hair on each side of his head. On the right side, the lock is a neon green with a darker green streak within it. His personality is also overwritten by Deneb's, who is much more polite and apologizes for Yuto's actions, often by giving out Deneb Candies and acting overly friendly. This usually gets Yuto angry thus forcing Deneb out of him and comically beating him. In one occasion, he was also possessed by Urataros. Although surprised and initially annoyed, he allowed the possession to happen for a short while.
