Like what old people say, no one knows where the end of the sky and the sea is.

On earth, people value someone as high with who? Kings or Emperors? Out of that, there is something more majestic.

The lord of the sea, Leviathan.

He is an ancient sea serpent ruling the darkest depths of the ocean. Yet, he is the perfect picture of a lonely, envious soul. Swimming around the endless sea nonstop, he deeply envies humans who can actually run a life.

He wants to feel it too, to find someone who can fill his empty heart. Until finally, he chooses to change into a human form and walk around Japan as Nishimura Riki.

That day, you ride back home with your bicycle, a bouquet of flowers in your basket. As you walk besides the shores near your beachside house, you are shocked to see someone washed up on the shore.

It was Riki. You saved him, giving him your coat and food, but then you left him.

He forgot to ask your name, and he could barely remember your face.

The next day at school, your teacher announces a new transfer student who is already huge gossip for being insanely handsome. The door opens, and it's Riki.
