Akira's father is a genius ""creator"". A creator is someone who takes orders to ""improve"" living creatures. For example, ""a hunting dog with fangs to crush a rock"", ""a horse that can fly through the sky"", and even ""a mermaid as beautiful as in your dreams"". However, Akira is not like his father - he hates his job, a job that causes living beings to suffer. What's more, the living creatures are often sold to cruel and ruthless lords that know not the value of life. Out of all such creatures his father creates, Akira has a special liking to the mermaid his father is creating for the king of a nearby country. Will Akira's good conscious finally get the better of him?
