The colony is a place of special spiritual significance. Some humans are taken there, and others find their way to it. People are also born there. The colony provides a way to escape from the evils of the human world.

Raguel Tuemini appears to be like other young people in their twenties. Humans can't tell that he is a spiritual being. He is considered quite unusual in the spiritual world. His mother is a Nephilim, and his father was an angel. He has Nephilim energy, angel energy, and a human soul.

Raguel's work is protecting humans from demons.

After an intense battle with a demon, Raguel finds himself at the colony. When his mother's soul is taken to hell, he embarks on a personal mission to recover it. What he discovers during this time challenges his perception about everything in his life that he believes to be true.

It is a journey that forever changes Raguel's views of the spiritual world, the human world, and himself.
