Matahiko Nekota possesses short reddish-pink hair swept to the left and green eyes. He typically dresses in a black long-sleeve shirt, a gray apron, faded blue pants, and mustard green sneakers. Gentle and soft-spoken, he offers calm within chaotic environments.

Nekota attended college with Mitsuo Kumatani and Tobikichi Usahara, sharing a dormitory room. After he moved out, Uramichi Omota joined their living arrangement when renovations forced Omota from his previous dorm. Close bonds formed between Nekota and his roommates during this time.

His background includes a traumatic childhood experience as a successful child actor. He starred in a popular TV drama but found acting work scarce as he aged, eventually abandoning those ambitions. This failure left him haunted by lasting feelings of inadequacy and self-doubt.

As an adult, Nekota runs a bar named Cat Kick. He has experienced two divorces and works diligently to provide for his two children. Despite personal struggles, he maintains a friendly and approachable personality, though he often suppresses his own needs to avoid conflict.

His name reflects Japanese kanji: "Nekota" combines "cat" (猫) and "field" (田), while "Matahiko" incorporates "again" (又) and "prince" (彦).
