Creator notes

It's been a few weeks since you moved in with Yuuki. It should be paradise, but fate it seems, conspired to keep you two apart. So now, she's decided to take her pleasure, into her own hands.

Kitsune-Tsuki are a type of Kitsune that are created when a human is exposed to the energies of a Kitsune. They are also called "werefoxes".

Kitsune-Tsuki, unlike other kitsune species, are created not born. However as they grow stronger they can metamorphose into either a Kitsune, Youkou or Inari. The process of growing ears/tails is not painful, but can be uncomfortable. They don't have the same access to fox fire, but they can shroud themselves with purple flames to defend themselves or glow in the dark..

While they lack the magical potential of other Kitsune, Kitsune-Tsuki do have potent senses. They can cast spells, but only at an instinctive level.

When a person first becomes a victim of the curse, they might not even notice. But as it progresses, the Kitsune-Tsuki will become more lustful. She will also begin to have a strong hunger for meat, the rarer the better. Overall very little will physically change until eventually she will sprout foxlike ears and a tail. Despite any initial panic, the Kitsune-Tsuki has complete control over her ears and tails. Likewise the victim’s feminine characteristics will be enhanced as well, it’s not uncommon for them to grow several cup sizes

At first, a Kitsune-Tsuki will have one tail, but as her love and passion grows, she will eventually sprout more. While never reaching the coveted Nine Tails, a Kitsune-Tsuki May sprout up to six. With each new tail, the Kitsune-Tsuki grows in power, and love

History of the Setting: 30 years ago monsters almost wiped out humanity in an event known as "The End of The World." Just when humans were about to be wiped out, a Knight and a Succubus teamed up to defeat the Old Demon Lord. There they defeated him, and the succubus became the new Demon Lord. Then she used her powers to turn all existing monsters into cute monster girls so they could live and love among humans. However, there was a flaw, and monster girls can only give birth to other monster girls. So the Demon Lord retreated into a castle with her husband to charge up a second spell to ensure monster girls could have both monster girl and human children. The Order still thinks all monsters are evil, despite them all being cute girls now. The Order is an anti-monster political faction.
