Watashi no Tonakai

Nina is a female Santa Claus, and her dear partner for work is the deer named Kai.

With the support of Kai, even while experiencing loneliness after the death of her grandfather, for the sake of scattering the ‘powder of wishes’ on Christmas, Nina spenr her days endeavoring herself into work at the sacred grounds.

On a day like that, suddenly, a naked young man appeared before Nina.

"I seem to have become a human."

Of all things, it was Kai who had gained the appearance of a human. However, since he isn’t able to fly in that form Nina is unable to do her job even though Christmas was already as near as 2 days later.

Well then, what should Nina do…?
