Talho appears in the film "Eureka Seven: Good Night, Sleep Tight, Young Lovers" as Holland Novak's girlfriend and a member of the Gekkostate crew. She and Holland share a history as childhood friends who endured military experiments alongside other war orphans. These experiments induced rapid aging, leaving Talho visibly aged beyond her 17 years during the film's events. This condition causes her physical health to deteriorate.

Her primary narrative function centers on her pregnancy. Discovering she carries Holland's child becomes the catalyst for his actions. This revelation shifts Holland's priorities, compelling him to abandon his quest for "Neverland" and cease his antagonism towards Renton and Eureka, moving away from seeking eternal youth for himself and the crew.

Within the film's storyline, Talho's role remains primarily defined by her relationship with Holland and her pregnancy. Frequent illness restricts her activity, notably preventing her from piloting the Gekko during a military attack, forcing Holland to take control. The narrative does not explore her background, personality separate from Holland, or grant her significant individual agency; she functions largely as a motivating factor for Holland's character arc.
