Odoren is a tall man with light skin and brown hair, consistently dressed in a black suit and cape. His most distinctive feature is a purple hat topped with a large yellow feather. His name originates from the Japanese word "odoru," signifying "to dance." Personality-wise, Odoren possesses strategic ability, enabling him to formulate plans to defeat opponents. However, this is counterbalanced by a pronounced cowardly disposition that causes him to avoid direct physical confrontations. While he takes considerable pride in his thieving skills, he exhibits a pragmatic willingness to abandon such pursuits when they become excessively troublesome or risky.

Alongside his partner Utaen, Odoren forcibly seizes control of the kingdom of Harmonia, disrupting its annual spring carnival intended to feature numerous Pretty Cure teams. As co-hosts of the event, he and Utaen maintain a superficially civil yet awkward demeanor toward the Cures throughout the festivities. During the carnival, Odoren orchestrates a scheme to isolate and kidnap the Pretty Cure teams' fairies. He lures the fairies away under the pretense of offering snacks while musical performances distract the Cures. This unusual behavior causes suspicion among the Cures to grow gradually during the event.

After their plot is exposed, Odoren traps most of the Pretty Cure teams in a basement and locks their transformation items inside a large chest. In a notable moment, he attempts unsuccessfully to transform into a Pretty Cure himself. The remaining free Cures reclaim their transformation abilities through song, thwarting his plan. Odoren then deploys minions called Robbens to attack the Cures. This attack is interrupted when Harmonia's guardian dragon, angered by the chaos caused by the thieves, awakens and rampages. Confronted by the dragon's destructive power and the utter failure of his ambitions, Odoren undergoes a change of heart. By the conclusion of these events, he abandons thievery entirely and takes up a new role as a janitor.
