* STory
100 years ago, a hero without a name brought down the demon king.
But that was long ago. The demon king rises again.
To conquer evil this time, a new hero, Airi, takes up her sword.
But on her first day of journey, her much-trusted and benevolent princess says:

"You cannot defeat the demon lord. That destiny belongs to the hero's companion."

A four-legged companion. A dog with white fur----------
Legendarily horny for human ladies... like Airi----------
