After failing to become a Tama-Artist, a group of people who wield Rei to control mystical jewels known as Tama, Lucien "Lucy" bitterly lost his mother to the "kyuketsuki" left in her by his father. He planned to seek revenge against those who made his mother's life a living hell. 

However, an unfortunate incident led to his death, and he ended up in the first Yōkai no Mon theater, where he gained power at a terrible cost. 

Lucy's actions become increasingly malevolent, but the unexpected news of his long-lost daughter forces Lucy to reexamine his actions. 

In a world where those with the Nana no Tsumi bodies, and reijuus are craved for, will Lucien's actions affect those around him, and hopefully find his salvation?

When the first human escaped the 2 Kage no Sumi (1), he entered a desolate realm between the Kage no Sumi and Yugenjina (2). The barren landscape was devoid of life, making even deserts seem like paradise.

After walking for a long time, he stumbled upon a solitary object, which he later named X-You Mountain.

As he observed the object from his palm, he found a peculiar, curly rock that promised to grant him a wish, as long as it wasn't selfish or harmful to others.

The first human asked how he could make the world better, and the rock replied, "You have to work."

From then on, humans were cursed to work, even when creating life.

Lucien was preparing to work on developing the Nonohana District, which would become the new base of Yurei.
