Yusuke Onodera (小野寺 ユウスケ, Onodera Yūsuke?, portrayed by Ryouta Murai) has a very self-confident and gullible childlike personality, a stark contrast to the original incarnation of Kuuga, Yusuke Godai. Yusuke supports the police in fighting the Gurongi and has feelings for Detective Ai Yashiro, as he fights to see her smile. When Yusuke first discovered the Arcle Belt, he is the first to be warned of Decade's existence as the "devil" by Narutaki. Yusuke rarely engages in battle while journeying with Tsukasa. He does, however, act as an inspirational figure to the other Riders, as can be seen with his aiding of Wataru, as well as his actions in the other Riders' worlds. However during the Rider War, though his world is destroyed, Yusuke still exists due to his traveling of the Nine Worlds. After he was turned into the KamenRide Card by Decade in The Last Story, but, he and his world are restored. Fortunately, he allowed to revive Decade and defeating the newly formed Super Shocker once and for all.
