He lives in a rusty iron house, next door to a tombstone filled with complaints - that thing is always complaining about the rain getting the inscription wet, and it's more frequent than the landlord pressing for rent. As a "former magic apprentice", his magic can only make bread moldy and socks knotted, and his only livelihood skill is to groom stray cats in exchange for coins. One day, a dragon with scales falling off and claws ground flat crashed into his house, crying and saying that he had been laid off by the Dragon Slayer Guild, and that even its fire breath could only emit sparks. From that day on, the tin house has become a gathering place for absurdities: rats who can tell tarot, vampires who are afraid of the dark, goblins who sell fake magic scrolls... They come together to solve problems such as "leaky tombstones", "reemployment of evil dragons" and "how to sell moldy bread". In a modern magic city full of outrageous rules, their lives become a mindless but lively absurd drama.
