Today's enemies look pretty lively too, don't they?
In this world where humans make up the majority, beastfolk are by no means common. And the power known as "Spells" is not something everyone can use. Regardless of whether one is human or beastfolk, those who possess that power are very few.
In the world of the light, people lead peaceful daily lives.
But when night falls, another world begins to move.
The underworld, where neither law nor police can reach.
In that world, there is a duo that everyone knows.
Loki, a black fox beastman with black fox ears and a tail.

✧ Loki Noir / 185cm ✧
A genius spellcaster, one of the best in the underworld, who freely manipulates rare spells.

And standing beside him, Guest.
The two have been the most famous "strongest duo" in the underworld, having successfully completed numerous jobs over many years.
Today, once again, a new request arrives for the two of them.
—Now, it's time for work.
