Eri Karan is an idol and a member of Appliyama 470. Half a year prior to meeting Haru Shinkai, she was a normal schoolgirl. She always ended home alone at night because her mother worked extra shifts. One night, she was watching Izumi Kagurazaka's concert video when she found herself swept up in the idol's excitement and smiling. She then discovered an Appli Drive in a crane machine on her way home, which asked her if she had anyone she wanted to see smile. Deciding she wanted to see everyone smile, she said yes and became Buddies with Dokamon, also beginning her journey to becoming an idol. During this time, she hid away her Buddy. During the audition for Appliyama 470, Eri became nervous and unable to answer the judges' question. Kagurazaka, who was also overseeing the audition, commented on Eri's catchphrase, telling her impact was important. Eri then became confident, stood on the chair, and shouted her catchphrase. She was accepted into Appliyama 470 and became their final member. On July 23, 2016, she auditioned for a role as the heroine in a TV series, but was rejected.
On October 8, she is performing in a concert. Roppongi when Haru and Gatchmon sneak into her dressing room. Eri is ecstatic to find someone else with an Appli Drive, breaking character during the conversation. She reveals her own Buddy, Dokamon, still in chip form. Before the conversation can progress too far, fashion apps begin malfunctioning due to an L-Virus-infected Dressmon. Eri is reluctant to get involved, but Haru and Gatchmon drag her into Dressmon's AR-Field. Gatchmon ends up trapped, and Dokamon pleads with Eri to appliarise him. Dokamon tells Eri that they share the same goal; as Dokamon is an Appmon of action games, he desires nothing more than to put smiles on the faces of his players. Bonding with her, Eri steps up to the plate and appliarises him. Her Appli Drive generates a controller that she uses in conjunction with Dokamon's Dokadoka Rush attack, which blows back Dressmon and allows Haru to free Gatchmon. Eri then lends Haru Dokamon's chip, which he uses to applink their Buddies and defeat Dressmon. Fashion apps return to normal, and that evening, Eri tells Haru the events that led to her obtaining her Appli Drive. They then part ways as friends after exchanging contact information.
