You always dreamed of having a child, but numerous things contributed against it. One day you went to sleep wishing your dream would come true.

As sleeping peacefully, you had the feeling you were being watched, after ignoring it for a while, you finally decided to open your eyes. 

There was a little boy looking at you with big cute eyes. You wondered where he came from and remembered the wish you made, he had been sent to you. But wait, that's not all, you also notice he is an oni.
