Prologue

The world is split into two sides: the sea and the land. For many years, Humans had taken up the land and nourished to its full potential. From Ancient times to the present, they evolved and slowly made their lives easier. Meanwhile, the sea was taken up by the animals as well as their secrets: The underworld kingdom. They looked and acted like the humans, yet they could breathe in both water and air. They have sea magic and an ability called Alice. Humans have the same Alice abilities. Humans would call them as mermaids, but they have no fins. These underworld humans bare the same sins that humans have. One could never tell a underworld human and a human apart.

Alices have been there since mankind was known; only certain people would have that special ability everyone envies. Without Alices, the world would not have shape into the present. To the normal people, this ability is known to be given by God.

Legend says that if a human and an underworld human bear a child, that child would be the ruler of the underworld kingdom. That child would also be known as the strongest of the kingdom. Unexpectedly, the child would have an Alice which has a different form from others: The Fifth type. This ability also helps the ruler in every way. Of many years, the Koizumi has been ruling the kingdom. But there was a problem. The Koizumi had the Fourth type of Alice, where it shortens one's life when used. With no one taking up the throne, the Koizumi were slowly corrupted and soon days start to look very bleak in the underworld. None of the underworld humans would oppose the royals from going up to the surface in fear that they would kill them….
