At the end of the year, Chiaki was urgently dispatched to the home of an Alpha with children, and was greeted by the children, ages seven, six, and two, and the hybrid Alpha, Ookami.

He was very concerned about the unruly Ookami, but on the night of his arrival, he began to experience a sweet and bitter change in his body...?
