Ashibe's Father, often addressed simply as Pa, is a central supporting character in the family’s daily life. He works as a carpenter, a trade he chose for himself despite being the son of the wealthy president of a large business conglomerate, Ashibe Commerce. His decision to pursue manual labor over joining the family enterprise is a defining aspect of his background, and it occasionally leads to dismissive or condescending attitudes from his father’s employees, who view his working-class profession as less prestigious. Physically, he is recognizable by his trimmed black hair, which is often held back by a thin white hachimaki headband. He has thick eyebrows, very small black dot-like eyes, and visible mustache stubble, and his typical attire is a practical, white short-sleeved shirt.

His personality is a blend of energetic playfulness and genuine sensitivity. While he can occasionally fall into the trope of a bumbling father figure, he is ultimately a loving and present parent who deeply cares for his wife, his son Ashibe, and their pet seal Goma-chan. This playful side often manifests in eccentric and impulsive antics. For example, he has been known to disguise Goma-chan as a cushion, a daikon radish, or even a neighbor's child to avoid detection by the landlord, and he once spontaneously appeared in Ashibe’s classroom, claiming the seal wanted to participate in lessons. This impulsive nature also gets him into trouble, as he has a habit of modifying his family's apartment without permission, which results in warnings from their landlord. Despite this chaos, he balances his wife’s more grounded and mature demeanor, and together they provide a stable and happy, if not wealthy, home for their son.

His motivations are simple and rooted in family happiness. He works diligently as a carpenter to provide for his household and ensures that his son and the unusual pet seal want for nothing in terms of love and care. His role in the story is primarily as a supportive and often humorous father figure who actively participates in the family's adventures. He was present when Ashibe discovered Goma-chan; initially mistaking the baby seal for a large fish they could eat, he was the one who correctly identified it as a gomafu seal and advocated for keeping it as a pet, showcasing his practical yet compassionate side. He has a brotherly dynamic with Ashibe, engaging in playful schemes, but also provides sensible and empathetic guidance, such as teaching his son about empathy to prevent him from trying to eat the seal.

The father’s key relationships are with his immediate family. He shares a strong bond with his wife, Ma, whose level-headedness complements his lightheartedness. With Ashibe, he is a constant and reliable companion, and he treats Goma-chan as a true member of the family, actively caring for the seal and accommodating its wishes. His relationship with his own wealthy father is defined by the different life paths they have chosen, a source of occasional tension but not animosity, as both have instilled in him a strong work ethic. In terms of development, the father’s core characteristics, background, and role remain consistent throughout the series. He does not undergo a significant transformation, serving instead as a steady, reliable, and affectionate anchor for his family’s whimsical everyday life. His notable abilities, aside from his professional skills as a carpenter, include his resourcefulness in creating disguises for Goma-chan and his unique, non-confrontational approach to problem-solving, preferring empathy and creativity over force.
