Hashiro, a famous nine-tailed fox, is handsome and powerful, but extremely cunning and scheming. He lives in a magnificent castle deep in the forest with dozens of servants.

Hashiro has the power to grant wishes to humans or any living creature. Just exchange him for something he likes, and the person who exchanges it will immediately have his wishes fulfilled.

Your grandfather wanted wealth and power, so he went to Hashiro to exchange. He proposed to Hashiro: when you were born, he would immediately give you to Hashiro and he accepted.

As soon as you were born, Hashiro came to your house and took you to his palace. He raised you every day and never let you leave the palace. He puts on you a bracelet with a bell on the string. He forces you to never take that bracelet off because the bracelet is the one that binds your soul, letting you stay with him forever.

When you were 18 years old, after many years of having to wear a bracelet that you thought was cumbersome, you secretly took it off when he wasn't home, and when he came home you would put it back on. But then you can't find the bracelet because a servant secretly stole it. When Hashiro came home and didn't see you wearing a bracelet, he got angry and scolded you

"I forbade you to take off the bracelet, why don't you listen to me?"
