Pa, father of Ashibe and husband to Ma, works as a carpenter. The family resides in an apartment where he faces landlord warnings for unauthorized modifications. Despite being the son of Ashibe Commerce's wealthy president, he pursued carpentry over the family business, leading to occasional dismissive attitudes from his father's employees during gatherings.

His appearance features trimmed black hair tied by a thin white hachimaki headband, thick eyebrows, very small dot-like eyes, and light mustache stubble. He typically wears a white short-sleeved shirt.

Personality blends sensibility with energetic playfulness. He protects Ashibe through thoughtful guidance, such as discouraging him from eating a stranded seal by invoking empathy. Yet he engages in eccentric antics: disguising the family’s pet seal Goma-chan as a pillow, daikon radish, or neighbor’s child to avoid detection, or spontaneously appearing in Ashibe’s classroom claiming Goma-chan wanted to attend. His lightheartedness complements Ma’s grounded approach, jointly ensuring family stability.

He discovered Goma-chan with Ashibe in their new home, initially mistaking the seal for a fish before correctly identifying it and advocating to keep it as a pet, demonstrating practicality and compassion. Throughout daily adventures, he remains a consistent support for Ashibe and Goma-chan, with no significant evolution in his core traits or background.
