Deneb

is Yuto Sakurai's Imagin who transforms into 's .
==History==
Acting against Kai, Deneb formed a contract with Sakurai, gaining a physical form within normal space-time due to Sakurai's wish to have the Imagin aid his past self Yuto. Aiding Yuto Sakurai, Deneb aided them in keeping Kai distracted from learning of his actual target. But when Ryotaro began to realize Sakurai's presence in the past, Yuto and Deneb reveal themselves to discourage the youth from ruining their distraction.
He also acts as a parental figure to Yuto, doing his best to make sure he lives healthy, including a need to serve shiitake to him, despite Yuto's deep hatred towards it (and usually resulting in a comical beating). Due to the fact he has a physical form in normal space-time, Deneb often appears in (poorly constructed) disguises in order to avoid standing out. At one point, Deneb accidentally caused Yuto to waste his second to last ticket. He decided to stop being a burden to Yuto and offers his services to Ryotaro, but it took Ryotaro and Momotaros' words to convince him to return to Yuto.
After Yuto uses his final card, Deneb feels at ease that Yuto wouldn't need to suffer the side effects anymore. That was until Sakurai comes with a new Zeronos Card and a full cardholder. Deneb drives the man out with intent not to have Yuto suffer again, but is forced to allow Yuto to use them when he wants to. While Yuto is negated from time momentarily, history is rewritten such that Deneb is contracted to Ryotaro, but is confined in the DenLiner like the Tarōs, during which he serves as the cook and takes Hana's position in keeping the Tarōs in line (with a noticeably more gentle approach).
When Yuto returns and assumes Zero Form, Deneb is alongside him as the Denebick Buster, to which he finds to be a surprise. However, when he finds out that he completely forgot about Yuto when he was erased from time, he is horrified and breaks down in tears. Deneb decides to make sure no one forgets Yuto by possessing him at night and passing out Deneb Candy to passers-by. However, Deneb learns the hard way that his actions do more harm than good when a young girl he befriends ends up inadvertently creating a contract with an Imagin.
Since then, Deneb pledges to Yuto that regardless of the circumstances, he will fight alongside him until the very end. But when the time does come, it turns out his adventure with Yuto created a time lag, allowing him to maintain his existence as he takes leave in the ZeroLiner, returning to aid the DenLiner crew during the events of "Final Countdown" before a fully healed Yuto joins it. Deneb then returns with Yuto to investigate Negataros by posing as crooks themselves. Soon after, Deneb tries to get Yuto and himself to join the DenLiner Police.

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 memory were altered, brainwashed, and/or captured. They were joined by Drive and Kiriko after Kotaro Minami managed to restore the Shift Car using Heisei Rider's original memories, Go Shijima after his initial encounter with Takumi Inui, 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 he's on the loose from both Shocker and the Rider resistance. Later, he and Go also encounters Sakuya Tachibana, and one of the other main Royal Card Kamen Riders, whereas Mutsuki Kamijo becomes an evil young leader of Shocker's branch, and Kazuma Kenzaki is initially held as a prisoner.

==Personality==
Being the opposite of Yuto, Deneb serves as his butler and comrade in battle. Though his intentions are noble, Deneb usually causes embarrassing consequences for Yuto, who comically beats him up for it. Although Yuto treats him with occasional disrespect; Deneb chooses to stand by his side out of friendship and loyalty, knowing Yuto to be a kind person. Due to the fact he has a physical form in normal space-time, Deneb often appears in (poorly constructed) disguises in order to avoid standing out. He carries around a basket that contains hand-made candies that have wrappers that bear his face called , which are made from milk, honey, and sweet melon. In a fight, Deneb is able to shoot bullets out of his fingertips that range from attacking an enemy to smoke pellets.
Due to Deneb's limited interaction with the Tarōs, he does not have names for them. However, he has on one occasion called Kintaros and Urataros as . Deneb is also the only Imagin other than Ryutaros to call Momotaros by his actual name as opposed to a nickname.

==Notes==

**Deneb's attire resembles Benkei, while his face is modeled after a crow tengu, which Benkei and Minamoto fought.
**Crows are closely related to magpies, and a bridge of magpies are used by Hikoboshi (represented by the star ) and Orihime (represented by the star ) to meet once a year in the story of Tanabata.

*After Yuto and Deneb's introduction into the show, Deneb briefly replaces one of the four Taros each second of the intro's final segment.
*Deneb is the only Imagin shown eating within the series (the Taros only demonstrate the ability to drink). He was shown eating watermelon on a hot day, later wearing a disguise made from watermelon skin by biting.
*Although he did possess Ryotaro once, Deneb is the only good Imagin from the series to actually never transform into Den-O nor became one of his forms. Had he done so, it's presumed he would become Den-O Vega Form.
**Deneb actually became the Vega Form of Den-O, but only in his newer version.

*The Denebick Buster is the only form-specific weapon of Zeronos' arsenal, limited to Zero Form's use.
*Deneb has signed contracts with Yuto in various points in time. He formed a contract with Past Man as he was struggling against Leo Soldiers, the present Yuto to assist fighting the Imagin, and his child-self "Yu" to defeat the Oni clan together.
