Musurika is a grey-haired humanoid wolf-like being with black eyes, wing appendages at the back of his head, and two crest-lashes below his eyes. He typically wears an eye-patch covering his left eye. Though his appearance is initially menacing, he possesses a caring and protective nature, especially toward children.

His background includes vast experience as both a soldier and traveler prior to settling in Anthole City. These travels exposed him to diverse races and environments, including interactions with Watchmen Golems, giving him familiarity with their behaviors. In Anthole City, he serves as the guardian of the sacred underground cavern and acts as teacher to Kikila, a young woolly shurigara.

He notably rescues Somali and Kikila after they enter the cavern without permission, intervening when a beast threatens them. Following this, he advises Golem against instilling fear in Somali, emphasizing the importance of compassionate guidance for children. His concern for others' safety is reinforced when he proactively warns Somali against venturing into the city's hazardous depths upon first seeing her near the railings, though his startling appearance causes her to flee.
