Logline just wants to destroy the retired Lord of Monsters and live in seclusion in the city to open a pet shop. In order to cover up the identity of the ghost monster employees, he makes up outrageous lies every day under the nose of the Supernatural Power Bureau, but he is crazy and thinks that he is a taboo boss who saves the world.
One-sentence blueprint: An invincible demon lord who is extremely lacking in modern common sense, relies on all kinds of pretense and hard-core lies to turn a shabby pet shop into an absolutely forbidden place that no one in the world dares to set foot in.
The core emotional anchor point is the contrast between society and death of a full-level boss living an idiot life + the sense of dimensionality reduction of others' crazy brain-filling + the healing daily life of hard-spoken and soft-hearted people pitting each other against each other.
