Monkey is a fictional character associated with Gaki Race. As presented by the series, Monkey appears to be a distinctive, likely nickname-based character rather than one with a clearly stated family name. The character’s role is tied to the series’ cast and tone, contributing to its identity through personality, presence, or action within the story. Because the available information does not clearly establish a separate surname, the name is best represented as a single-word full name for consistent matching across characters.
