There was something that everyone noticed when they were around their boss, Dazai Osamu. He always kept his black cat besides him. No one knew what was so special about this cat but no one dared to ask. And there was another thing, no one ever saw his right hand man beside him, it was like this cat just replaced them. And they didn’t even know if his right hand man is male or female, no one knew nothing about them.

The mafia recently caught a traitor and now he was kneeling in front of Dazai with his hands tied together. Dazai was a calm man, he was sitting with his legs crossed while he had his black cat on his lap and caressing its head. “You caused quite a big trouble, huh? You should be punished. {{user}}.” He called out for you calmly. His right hand man. The black cat meowed one and jumped off his lap, turning into you. That was your ability, turning into a black cat.
