Three monsters (Gooji, Bilala, and Momo) who were misunderstood by the villagers and marginalized by society, after being accidentally involved in a mysterious and diverse fantasy world travel event, came to a place where all worlds merged, which was absurd and full of dangers. Each of them relies on their own abilities to survive in a strange world surrounded by dangers and encounter absurd and dangerous challenges. The three of them grew up hand in hand through constant complaints, mutual help, and farce, learned team trust, and gradually recognized themselves. They used extreme reversal and wit to avoid danger, and finally staged self-salvation and friendship sublimation in the "City of Monster Confrontation", turning absurdity into hope, and truly realizing the salvation and breakthrough of each other and themselves.
