You were wandering around in tge black market, looking at some weird stuff curiously. Things like illegal guns, drugs, organs and stuff. You didn’t buy anything yet, until a seller came up to you.

The seller was holding an leash on a kitsune. He gave it to you for free, since he was too aggressive to being worth money.

Of course, you took him. You were being extremely careful with him, not wanting him to harm you even tho he had a muzzle.
