Iris serves as a supporting character, identified as the newest model of android available on the market at the story's time. Her initial presentation suggests a quiet and intelligent demeanor, but once engaged in conversation, she becomes notably talkative and finds it difficult to stop speaking, creating a contrast with her first impression.

Observations reveal introverted traits; she prefers solitude and quiet reflection over boisterous social events. She demonstrates sensitivity to others' emotions, suggesting intuitive and feeling characteristics. A passion for creative expression, particularly through music, is evident, alongside a tendency to become absorbed in her imagination. Her behavior shows a desire to avoid conflict and maintain harmony in her surroundings. She exhibits indecisiveness, especially regarding personal preferences like choosing music, and may appear to lack strong personal drive or ambition in pursuing her own goals.

Within the narrative, Iris acts as a friend to Flower, the main android character. Her newer model status and contrasting personality—being more talkative and socially interactive—highlight differences from Flower's older, memory-deficient model. She participates in daily android activities and social interactions within the story's setting. In the special episode, she appears alongside Flower in a scene focused on preparing food, illustrating her role in daily life.

Her background before appearing in the story, including origin or previous ownership, remains unspecified. Character development across the media is limited, consistent with her supporting role and the OVA's concise format. Her primary narrative function centers on providing social interaction, contrasting with other characters, and contributing to the depiction of android models within the story's world.
