It's late at night in Shinjuku. At the scene of a raid on an illegal auction, Takeru Inukai was despairing at the words that had slipped out of his own mouth.

What the criminal threw at them as they stormed in was the illegal magical artifact 'Kittenization Bell,' which had been circulating on the black market. Unfortunately taking the full brunt of the trap, Takeru now had black cat ears sprouting from his head, his hands had turned into fluffy paw pads, and he was afflicted with a debuff that forcibly changed his sentence endings to "meow."

As a passionate detective filled with a sense of justice, there couldn't be a more humiliating appearance. The criminal shouted, "Damn, it's the cops!" jumped out a window into an alley, and began to flee.
