Ashibe, whose full name is Ashiya Ashibe, is the young protagonist of the anime Shōnen Ashibe GO! GO! Goma-chan. He is an elementary school student, specifically in the first grade, whose life changes dramatically after moving to a new apartment with his family. The story begins when a small spotted seal pup falls from a passing truck, and Ashibe decides to keep it as a pet, naming it Goma-chan.

In terms of personality, Ashibe is portrayed as a typical young boy, navigating the everyday adventures and challenges of childhood. The series emphasizes the cute and pleasant nature of his daily experiences, highlighting his kind and caring disposition, particularly towards his unusual pet. His life revolves around the typical routines of a young student, including school, friends, and family, but with the extraordinary addition of a seal in his household. His motivations are simple and heartwarming, focused on enjoying his time with Goma-chan, his family, and his classmates, and dealing with the humorous situations that arise from a seal living in a human home.

Ashibe's role in the story is central as the anchor of the family and the primary companion to Goma-chan. The narrative follows his perspective as he goes to school, interacts with his friends like his close classmate Sugao Anan, and comes home to his family. He is the bridge between the human world and the comedic chaos introduced by Goma-chan. Key relationships in his life include his father, who works as a carpenter and is a loving, though sometimes bumbling, parent; his mother; and his wealthy grandfather. The grandfather is a successful businessman who dotes on Ashibe, famously using his resources to buy businesses in an effort to help find Goma-chan when the seal gets lost. The family dynamic shows that while his grandfather is rich and his father is a modest carpenter, both are dedicated to Ashibe's happiness.

Regarding development, Ashibe grows through the various experiences he shares with Goma-chan and his family. The show depicts the everyday lessons of responsibility, friendship, and family bonds. The contrast between his father and grandfather also introduces themes of choosing one's own path in life, a subtle layer of development within the otherwise lighthearted and comedic narrative. As for notable abilities, Ashibe does not possess any superhuman or fantastical powers. His primary ability is his endless patience and adaptability in dealing with the mischievous and often inconvenient antics of his pet seal, Goma-chan, maintaining a cheerful and loving attitude throughout their unusual life together.
