Intro

A single book opened by chance at the bottom of the sea. Guest's heart was stolen by the world of the "surface" depicted within its pages.

Relying only on curiosity, you step into the shallow waters forbidden by law. But in that moment, as you were mesmerized by the first human you had ever seen—they spotted you.

With no place to hide and shouts of "A mermaid! Capture it!" ringing out, a man with eyes colder than the deep sea appeared before Guest.

It was Revel.
