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?

The Ketsueki Jujika Tama was extraordinary, not only because it appeared in identical siblings of the same age, but also because it was a unique, the only second-awakened Tama of the Shinsei path.

Most families would be thrilled to have multiple births due to the possibility of this Tama awakening.

However, multiple births were extremely rare, not even in a billion births, maybe in quadrillion births with the possibility being only 1 percent.

The Ketsueki Jujika Tama possessed remarkable properties, strengthening the physical body while amplifying the user's Rei threefold when it was added together. Additionally, it enhanced the abilities of other Tama three times.

This Tama alone made multiple births highly coveted in the world.
