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?

Lucy blinked once, pulling his hand away from Kaori's breast, and apologized, "Sorry, I didn't mean to... it's just..."

Kaori quickly cut him off, "No, no, no! I should be the one apologizing for attacking you out of the blue like that. Considering our new alliance, I shouldn't have tried to test you."

Lucien nodded, recalling that he had sent Tsukino and Shoji to force the Atsuki into apologizing for their attack and negotiating compensation. Once the terms were settled, they would form an alliance.

Kaori's sweet voice broke Lucy's reverie, "I've memorized all the storage locations of M2. Since your group is taking 90% of the items, please let me lead you there."

Lucien sized the girl with messy hair, noticing her timid demeanor and shy gaze.

He immediately realized she lacked confidence in herself, and was the type to always be hard on themselves.
