Biography

Participation in the DGP

Daichi Isuzu chose to participate in the Desire Grand Prix in order to fulfill his desire of controlling all the memories of humanity, in order to attain omniscience.

After surviving to the end of a previous Desire Grand Prix as a finalist, Daichi was brought back into the Desire Grand Prix by Chirami for a new season of the game, in which one of them would secretly be chosen to be a "Dezastar" and sabotage the other players.

During the "Jyamar Ball" round of the game, Daichi came across Keiwa choosing to spare a Jyamato. Keiwa explained that he had heard the Jyamato repeat something one of the eliminated players of the game had told him, and that he believed the Jyamato to be the players of the game who had perished. However, despite knowing this, Daichi would later use this incident to frame Keiwa as the Dezastar and get him eliminated, in order to bring himself closer to victory. However, the other players figured out Daichi's ruse and believed him to be the Dezastar instead, voting him out at the end of the round. But as Daichi was eliminated, he was revealed to not be the Dezastar.

Joining the Jyamato

Following his elimination, Daichi was approached by Beroba, who offered him a spot in the Jyamato as one of their Riders. Daichi accepted, viewing it as another way he could accomplish his desire. He was soon joined on the Jyamato side by another eliminated player, Michinaga Azuma.

As Archimedel came close to finishing building a massive Jyamato army, Daichi went with Michinaga and Beroba to complete their side of the plan, that being to steal the game master's Vision Driver. After Chirami decided to stage a "hide and seek" round of the game using himself as Kamen Rider Glare, the three Jyamato aligned individuals confronted him to steal his Driver. Michinaga and Daichi were able to easily overpower Chirami and force him out of his transformation, enabling Beroba to seize his Driver. However, their interference prompted the DGP sponsor Ziin to intervene and assume his Kamen Rider form in order to stop them.

After Beroba used the Vision Driver to hijack the Desire Grand Prix and convert it into the Jyamato Grand Prix, with the goal of seizing Niramu's Vision Driver and using both of them to access the Goddess of Creation, Daichi stood on the sidelines and watched as Michinaga and the other JGP participants fought against the DGP Riders in various rounds. At some point, Daichi and Beroba accessed the recordings in the Vision Driver and discovered the truth about Neon being a creation of the Goddess, as well as the fact that the Goddess was really Ace's mom.

During the final round of the game, a "Heaven or Hell" match, Daichi approached Ace at Beroba's direction and told him that his mother had willingly become the Goddess of Creation and sacrificed the happiness of others in order to have a child, but Ace refused to believe it.

Desire Royale

After Suel intervened to put an immediate stop to the Jyamato Grand Prix, Daichi became one of the participants in the "Desire Royale" he initiated. The first round involved collecting the Core IDs of past players, with the player who collected the most getting to choose one Rider to be eliminated from the game. During the first round, Daichi attacked Na-Go and Hakubi but was driven off when Tycoon and then Geats arrived. Later, Daichi approached Neon and Sara and apologized for attacking them earlier, giving them the Core IDs he collected as a show of good faith.

During the next part of the round however, Daichi revealed Neon and Sara's location to Buffa in an attempt to get them eliminated while he collected even more Core IDs to make himself the victor. However, Buffa chose to go after Daichi instead and confronted him as he was collecting Core IDs. Despite his best efforts, Daichi was unable to stand up to Buffa's Jyamashin form and was eliminated when Buffa tore out his Core ID and cracked it. Before disappearing, Daichi vowed that he wasn't finished yet.

Becoming the next Jyamato Gardener

Beroba was later able to recover Daichi's Core ID and use it to restore his memories. After Ace stopped the Grand End, Daichi became the new gardener of the Jyamato and cultivated a new kind, the miniaturized Parasite Jyamato, which he sent out to infect people and turn them into Pawn Jyamato. This led Ace to hold a new Desire Grand Prix to deal with the remaining Jyamato.

Daichi then approached Sara in public and poured Parasite Jyamato on her, causing them to transform her into a rampaging Pawn Jyamato. While Michinaga arrived to confront the Pawn Jyamato, unaware that it was Sara, Daichi was confronted by Ace and Keiwa and revealed to them that he had transformed himself into a Jyamato as well. As Daichi became the Marrella Jyamato and fought Geats IX, Keiwa witnessed Michinaga unwittingly kill Sara and became enraged.
