Azarashi acts as the club's mascot, existing unseen by other members and creating a distinct narrative role. Visually presented as a seal with white hair and black eyes, the character carries a seal plushie and often wears a seal-themed hoodie, demonstrating a marked affinity for seals that includes expressing a wish to become one in a future life. Frequently seen holding a book, Azarashi exhibits studious tendencies. In group interactions, the character assumes a background position, listening more than participating due to reservedness. This quiet nature occasionally leads to exclusion from conversations, though gentle and friendly behavior maintains group integration. Azarashi contributes through supportive presence rather than direct action and intermittently serves as an unseen narrator. Personality traits encompass introspection, empathy, creativity, imagination, and a strong value for authenticity, potentially manifesting as playful engagement with stuffed animals or imaginative role-play. The character also displays responsibility and loyalty, coupled with anxiety about uncertainty and negative outcomes that prompts preparatory planning. Self-doubt regarding decisions occurs, alongside reliance on trusted individuals for reassurance.
