Kuro & Yuki

Kuro (クロ) and Yuki (ユキ) are a mated pair of Inferno Hounds who became the first sapient creatures befriended by the main character Hiraku Machio during the beginnings of his farm in the Forest of Death.

It is later revealed that they are a special variant called Inferno Wolf Emperor and Inferno Wolf Empress.

Character History
Prior to the beginning of the story, Kuro was a lone wolf who wandered through the Forest of Death doing what he wanted and hunting when he needed to eat, until one day he met Yuki. The two faced each other with the latter being the winner. After his defeat they stayed together as they wandered through the forest until one day he noticed that Yuki had become pregnant. This all changed when they came across the king of the forest, the Grapple Bear. They were so weak from that encounter that even their former preys were chasing them, they fled until they reached the center of the forest where they saw a human living alone, Kuro wondered how a human had managed to live alone in that place so they approached him.

Initial Meeting with Hiraku Machio, the Farmer
Hiraku sensing their intentions invited the pair into his farmland which he had recently had fenced off crudely with downed logs and ditches. Kuro and Yuki, prepared for the worst, approached the farmer and to their surprise, they were greeted with kindness. 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 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.

Early Life on Farm
Kuro and Yuki would show their loyalty to Hiraku by protecting the farmer from dangerous animals of the forest as they tried to invade his farmland and they would introduce him to new friends, such as the demon spider Zabuton. Whom with Kuro and Yuki 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 and Yuki 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.
