Ichimaru, a service-model android from the same production year as the main protagonist, works as a vegetable vendor and boasts a comedic persona marked by playful antics and mannerisms inspired by Japanese comedy traditions. Her cheerful, approachable nature shines through daily interactions with customers, cementing her role as a beloved community figure.

Her bond with the main android character stems from their shared origins as outdated models, framing their friendship through the lens of mutual resilience in a society pushing them toward obsolescence. Though devoid of complex personal history or memory struggles, Ichimaru’s steadfast optimism contrasts the narrative’s broader tensions, subtly enriching themes of android integration and purpose.

Her narrative purpose remains focused on providing levity through situational humor and reinforcing the solidarity among older androids, with no established evolution or central plot influence across official sources.
