Kuro & Yuki are mated pair of Inferno Hounds which became the first sapient creatures to befriended by the main character Hiraku Machio on the beginnings of his farm in the Forest of Death.

Hiraku sensing their intentions invited the pair into his farmland which he had recently had fenced off crudely with downed logs and ditches. He would share large boar to them to begin the what turn into a bonding event between him and the two inferno hounds whom he at this time assumed were wild dogs. Yuki (female) would reveal she was about give birth, and Hiraku would offer him simple shelter for her to give birth to her first litter. This act of kindness for shelter and food would create a friendship with this human in middle of a forest.

Whom with Yuri & Kuro aid Hiraku's endless task of farming the land and raising crops for all to eat. Since it's his desired choice of career and for survival sakes.

Kuro & Yuri would shortly later intercept a human like woman lurking on edge of the farm. Initially attacking her when it turns out she is a Vampire, named Ru Rurushi who is taken in by the farmer and becomes his lover.

Later Life on the Farm
As time passes, Kuri & Yuri would continue to breed more pups at the farm, with previous generations of inferno hounds heading into the forest and world to adventure. Despite the continuous generations of Inferno Hounds leaving the farm for outside world, Kuri & Yuri would remain at their adopted home with Hiraku and now his growing village of friends.

They would end up becoming the leaders of a huge pack of Inferno Hounds, becoming steady and reliable citizens of the village of Taiju.
