Nuko

A mysterious white creature existing in the world of the story. It feeds on things like bullets. The name was given by Chito and the others for convenience when they first encountered it. Although it does not have vocal organs, it has a high learning ability to understand language and can communicate through radio waves, allowing it to converse with humans if they have a radio. Additionally, it can unlock padlocks and electronic locks by transforming its forelegs into master keys or accessing them electrically. When it reunites with Eringi and the others, it is reluctant to part with Chito and the others, but is sent off after being advised on the importance of companionship.
