This narrative recounts the tale of a creature inhabiting a contemporary urban environment. On a daily basis, it camouflages itself as an ordinary human being to assimilate into human society. Ultimately, it uncovers and joins a community of similarly peculiar beings, forming a cohesive group.

The story begins with the protagonist, a black, furry monster. One morning, he wakes up to the sound of an alarm clock. He opens his wardrobe, takes out a set of human-shaped leather cases, carefully puts them on, adjusts them, ties a tie, and gives himself one last check in the mirror before grabbing his bag and heading off to work.

The scene shifts to the meeting room, where the protagonist is giving a presentation to his colleagues. Unfortunately, no one seems to be paying attention. At this moment, the zipper of his leather case slips open, revealing a glimpse of his black fur inside. Quickly, he pulls the zipper back up. Since no one is listening, no one notices this small mishap.

On the subway ride home from work, the monster suddenly feels a surge of uncontrollable energy and nearly breaks free from his suit. Fortunately, he manages to cover his belly with his briefcase just in time, ensuring that the woman beside him doesn’t notice anything unusual.

Later, he visits a jazz bar, orders a drink, and sits down. Suddenly, the female singer on stage starts convulsing, and the monster inside her bursts out. Seeing this, the male singer beside her also removes his leather suit to reveal his true form. The protagonist, excited by what he sees, rushes toward the stage, sheds the confines of his own leather cover, and reveals his true self. Then, the audience below also removes their leather covers, exposing their various monster bodies. Together, everyone joyfully dances in harmony.

The theme of this story is to emphasize that individuals should not compel themselves to assimilate into social groups. Each person possesses inherent uniqueness, and it is essential for everyone to value and embrace their individuality without experiencing anxiety over the inability to integrate into mainstream society.
