Ryōka Dōba is a 15 to 16-year-old student at Seirei Private High School, introduced as a secondary figure in the *Aikatsu Planet!* anime during the inaugural episode "Suddenly an Idol," where she appears in school-based scenes. Her role remains peripheral, with no dedicated exploration of her backstory, motivations, or personal growth across episodes, films, or supplementary media. In the 24th episode, "Everyone’s Request," she briefly surfaces in a Dressia performance montage but goes uncredited in the closing titles due to the brevity of her appearance. Her surname merges the Japanese characters for "hall" (堂) and "place" (場), while her given name fuses "cool" (涼) and "fragrance" (香). Available materials offer no insights into her relationships, personality, or narrative impact beyond these instances.
