Description:
One thousand years ago, a monster called Enka brought destruction to the world. Before the monster was destroyed, it swears that one thousand years later its child would be born and bring despair to the world. One thousand years later, by using DNA testing, researchers manage to identify several people who could be Enka's children. In order to determine which one of them is the child of Enka, the researchers decide to turn them into a family with the head of the researchers acting as the father. The members of this eccentric family includes a 20 year old girl who wears cat's ears and tail and thinks that she's a God, a boy who suffers from sexual identity disorder, a lion who can speak and understand human language, a 3 years old land-battle-type biological weapon, a girl who can show demonic face, and a Jellyfish girl who only eat high-class cuisine.
