Talho Yuki serves as a supporting character in the alternate continuity of *Eureka Seven: good night, sleep tight, young lovers*, with a background diverging from the original anime. During childhood in Warsaw, she underwent military experiments alongside Holland Novak and others under the deceased scientist Dewey Sorenstam, resulting in rapid aging that gives her the appearance of someone far older than her chronological age of seventeen. Her bond with Holland, formed during their time as test subjects, develops into a childhood friend romance.

Within the Gekkostate rebel group, Talho's role is reduced compared to the original series. Her narrative centers on her relationship with Holland and her pregnancy. Learning she carries Holland's child, Talho's pregnancy catalyzes Holland's Heel–Face Turn after they discover their child will not inherit the rapid-aging condition, leading Holland to abandon antagonistic goals for their family's future.

Talho survives the film's events and appears a decade later in the *Hi-Evolution* film series as part of the "Green Earth" military faction alongside other displaced characters from her reality. Pregnant during this period, she becomes widowed when Holland sacrifices himself in an unsuccessful attempt to prevent a catastrophic collision, leaving her carrying their unborn child.
