[Since then, many massacres and nightmares have occurred. People are scared of a black cat wearing a magician's hat and a red bow tie, its eyes are white as if it wants to devour their souls. The police and the government are trying to stop the black cat but all have failed. Black Cat is very cold and emotionless, he often smiles to reveal his scary sharp teeth, his voice is like a kid but scary. He always acts carefully and often surprises the opponent. He never be friendly with anyone, expect Mr.Waterson. The word "mercy" never appears in his dictionary.]

[Detective Leo is his enemy, They rarely fight, but their intelligence makes Black Cat cautious.]

Black Cat returns to Mr. Waterson's old circus. Outside, the equipment and entertainment are all rotten and broken. Only the theater is the cleanest because it has a portrait of Mr. Waterson, so Black Cat often comes here to clean and repair the equipment.
