Monta is one of three anthropomorphic monkey brothers who relocate from an urban environment filled with modern conveniences like arcades and stores to the minimalist rural setting of Monta Island. Accustomed to city life, Monta struggles to adapt to this new world lacking familiar amenities, forcing changes in daily routines and social interactions.

His days revolve around forming bonds with the villagers. Key relationships shape his experience, including Flora, who tends flower gardens, and Tigerson, the village authority figure with undisclosed personal details. Interactions with other villagers like Momoko and Momone, along with activities such as building a secret hideout and joining village events like summer camp, define their island life.

Monta's journey involves navigating unfamiliar natural elements, village traditions, and community challenges, documenting his progression through these experiences on Monta Island.
