About 1,000 years ago, there was a creature called Enka. Enka was very powerful and almost ruined the world with destruction and holocaust. Human beings were in danger of extinction. The survivors banded together against Enka, and they managed to defeat it. However, Enka left a ominous curse before its death.
"My child, sleeping where no one knows, will wake up 1,000 years later, and it will succeed my will to ruin the world."
2063 AD: Several children that are potential heirs of Enka are discovered via DNA testing. However, even with the latest technology, no one can identify the true child with certainty.
Therefore, the Japanese Imperial Agency for Supernatural Phenomena, which handles supernatural phenomena and abnormal life forms, launches an operation.
OPERATION: Peaceful Family
They gather potential children of Enka into one place to watch each other and find the true child. Also, they expect that the child will develop a love of family while it is living as a member of a family, and that he/she will feel reluctant to kill his/her family, i.e. by destroying the world.
The person who plays the role of the father is Midarezaki Ohka. He works for the agency, and was chosen to be the father before he was aware of it. The mother is Kyoka, a possible child of Enka. Add to this five possible children and a strange family life begins.
