Biography
When he was a young boy, his grandfather told him the story of the Star Fragment in the same place Gingka Hagane grew up in Koma Village. He was told to not let it fall in the wrong hands.

The New Star Fragment
Yuki is sitting in his observatory waiting for the star fragment that was supposed to arrive and he witnesses as it splits up into 10 pieces and one comes shooting down at his observatory. When Yuki awakes, he sees that his bey is shining. He realizes that he needs to tell Gingka and the others about this development so he leaves but isn't aware that Johannes is following him under orders from Pluto.

Later, Johannes engages him in a battle to prevent him from telling Gingka and the others. Yuki is continuously beaten down until Kyoya arrives whom Yuki asks for help but he declines. Not very soon after, Gingka arrives and helps Yuki to which Johannes takes his leave. Yuki says that Gingka is a Legendary Blader but before Gingka can ask what this means, Yuki passes out.

The Legend of Nemesis' Revival
When Yuki wakes up, he informs Gingka and the others of the legend of Nemesis' revival which his grandfather told him. Ryo proposes that man is most likely from Koma village because that legend has been passed down in the village.

He then leaves on a journey with Gingka and the others to find the legendary bladers following Gingka's battle with Johannes. Yuki calculates that one could have fallen on a remote island and they go there to check. There they find out that the Legendary Blader is none other than Ryuga who defeats Kyoya Tategami and then Gingka. Yuki battles him to make him join them and he awakens as a Legendary Blader. Despite that, he is still defeated.

Later, he trains with Kenta Yumiya and later with Gingka and Kyoya on the island to master his legendary power. He combines forces with Gingka and Kyoya to stop the lava which was coming out of the volcano that just erupted. They are successful. Kenta later leaves the group to get strong on his own.

Gateway To Success
Later Gingka and the others head to China where they train for an upcoming tag-team tournament called the Gateway To Success where they suspect that another Legendary Blader may be. Yuki becomes Gingka's partner and together they defeat Chao Xin and Mei-Mei and later Dashan Wang and Chi-yun Li, improving their teamwork. In the fiercely contested final battle, he and Gingka lose to Bao and Aguma who is a Legendary Blader.

Destroyer Dome
Later after meeting Team Excalibur, he goes with Gingka and the others to Europe where he and the others learn about a bey known as the Sword of the Gods and later he is a spectator to the Destroyer Dome tournament where they learn that a blader named King and his Variares D:D is also a Legendary Blader.

Mist Mountain
In the aftermath of the Destroyer Dome tournament, Yuki and the others go to Mist Mountain where they meet the Guardian Of The Temple, Dynamis after he helps solve a puzzle. He tells them the real legend of Nemesis' revival. When Johannes and the others arrive there, he is one of the bladers to engage them in a battle. Kyoya laves the group after a fight with Aguma.

Beyster Island Tournament
Later at the Beyster Island tournament, Yuki participates alongside Gingka, King, Masamune and the others. He losers because he was not able to make it in time to the final point. There he also learns that Chris is also a Legendary Blader.

The Revival of Nemesis
Later he goes to the Mayan ruins where Nemesis is being revived with Gingka and the others where he battles Aguma but soon Tithi shows up with Kyoya and Yu and takes his place. He then goes on ahead with Gingka and fights a Nemesis blader, Cycnus while Gingka battles Chris. After winning, they go to the chamber where Nemesis is. Here he witnesses Proto Nemesis, Zeus's Barrier and the birth of Diablo Nemesis. He fights it alongside the other legendary bladers (except Aguma) but have to retreat due to the temple collapsing. At headquarters the team discuss a plan of attack. When they set off to stop Rago, they are ambushed by Johannes and the Nemesis Bladers. Yuki and the others fight hard along with Aguma who came to help. The Bladers defeat the servants of Nemesis and move on.
