Cikapasi is a young Ainu boy who resides in the same kotan, or village, as the main character Asirpa in Hokkaido. His past is marked by tragedy, as his parents and older siblings all passed away from smallpox. Following these losses, the elders of his village took on the responsibility of raising him. Before their death, his parents gave him his name, Cikapasi, which carries a dual meaning: "he who makes birds fly," as well as a more crude anatomical reference that hints at his personality.

In terms of personality, Cikapasi is a curious child who is easily amazed by great feats, such as the hunting skills of the Matagi soldier Genjirou Tanigaki. Despite living in a close-knit community, he is somewhat of a loner and does not typically play with the other children of the village. He has a strong interest in hunting and shows eagerness to help others during their hunts. He also has a notable and immature fascination with women, particularly the fortune teller Inkarmat.

Cikapasi's primary motivation is a desire for family and belonging. Having lost his own family, he is searching for a place to belong. This drive leads him to secretly follow Tanigaki and Inkarmat when they leave the village to search for Asirpa. When caught, he pleads to join them, stating that he has no one waiting for him at home. He becomes attached to the pair, excitedly embracing Inkarmat's suggestion that they pretend to be a family to appear less suspicious in their travels.

Within the story's narrative, Cikapasi serves as a companion and a source of levity. His role becomes more significant when he joins Tanigaki and Inkarmat on their journey. His key relationships are primarily with this pair; he views Tanigaki as a strong male figure and fatherly presence, and he harbors a childish crush on Inkarmat, seeing her as a maternal figure. These bonds give him a new sense of purpose and a surrogate family, which is a central element of his character arc.

Regarding development, Cikapasi begins as a lonely orphan on the periphery of his village. Through his decision to follow Tanigaki and Inkarmat, he actively seeks a new life for himself, demonstrating a brave and determined side. His journey is one of finding a new family and learning from the adults around him, transitioning from a passive observer to an active participant in their travels.

His notable abilities are not those of a fighter, but rather stem from his upbringing as an Ainu. He possesses a basic knowledge of hunting and the outdoors, showing eagerness to learn more. He is also quite observant, as he managed to follow Tanigaki and Inkarmat for a significant distance without being noticed immediately. His most defining characteristic is his resilience and his longing for connection, which drives his actions throughout his appearances.
