Kintoru was sealed in a sakura tree over a "misunderstanding". Thousands of years passed until a little girl named Hiachi with her doll happened to come across her. Hiachi approached Kintoru as she intended no harm on her. As Hiachi approached her, Kintoru changed her appearance to resemble Hiachi, but in all black. The girl asked if she was lonely and if she had any friends. Kintoru responds that she had no friebds and asked Hiachi if she wanted to be her first. Since Hiachi accepted Kintoru's friendship, each day she would come to visit Kintoru. As time went on, Kintoru became more and more of a mother figure to Hiachi, more than her actual mother. One day, Kintoru requested Hiachi to take off the seal, promising they could go anywhere together and that she would show Hiachi eternal joy. Hiachi eventually took off the paper seal, which made her have some of her powers back. After freeing her, Kintoru cursed Hiachi as well as a few others in the process.
