Kō is a supporting character in the anime adaptation of the manga Caressing the Nipples of My Hibernating Bear. He is a friend of the protagonist Nowa, a bear who lives in a rural forest town. When winter arrives and Nowa must hibernate, he entrusts the care of his adopted son Airi, a dog, to Kō. This indicates that Kō is a trusted and reliable companion within Nowa's social circle. His primary role in the story is as a caretaker for Airi during Nowa's long hibernation period. Kō's relationship with Nowa is one of mutual friendship and trust, and he serves as a temporary guardian for Airi, ensuring the young dog is looked after while Nowa is asleep. Beyond these details, available information does not specify Kō's species, personal background, deeper personality traits, motivations beyond helping his friend, or any notable abilities or character development. His function in the narrative is largely defined by this caretaking duty and his connection to Nowa.
