Poniki is a supporting character in the anime Mamekichi Mameko NEET no Nichijō. He is an adult man with black eyes and short black hair, and he is the husband of Aneyoshi, placing him within the extended family circle of the main household. His defining traits are gentleness and a deep, devoted love for his wife. One of his most distinctive habits is keeping a personal collection of photographs of Aneyoshi's unusual sleeping faces, a folder he turns to when he feels discouraged at work; looking at these images lifts his spirits. This practice illustrates his affectionate nature, his quiet appreciation for small and imperfect moments, and his tendency to find emotional support in his marriage. His motivation centres on cherishing and caring for his wife, and his warmth toward her is portrayed as sincere and enduring. In the series he appears as a steady, kindly presence in family life rather than the focus of his own storyline, and his devotion to Aneyoshi remains consistent throughout. His notable ability is this practice of documenting and revisiting private, tender moments of his wife as a way of restoring his own morale.
