A young boy who has been immortal for 800 years. He has a face of an angel, but the soul of the devil. Masato would give mermaid flesh to a woman and have her pose as his mother until she was deemed useless. Despite his childlike appearance, eight hundred years of loneliness and wandering have turned Masato into a soulless monster. His latest mother figure, Misa, actually gave him the name Masato. He found her during WWII after she had lost real son in an air-raid. Sixty years later, Mana and Yuta came across Misa and Masato, and Masato set his sights on making Mana his latest mother-figure. He drove off in a car and plowed right into a truck but it was implied that he was still out there searching for another mother.    

According to an ancient legend, mermaid's flesh can grant immortality if eaten. 500 years ago, Yuta unknowingly ate a piece of mermaid's flesh. For centuries, he travels across Japan, hoping to find a mermaid, thinking she may be able to make him a normal human again. When he finally finds one, he discovers that she and her companions have been raising a girl to be their food so they can eat her and take on her youthful looks. That is how mermaids stay young. Yuta kills the mermaids and rescues her, but she has already eaten some of the mermaid's flesh. Although he had to kill the mermaids, Yuta isn't too disappointed. Yuta's once lonely existence is now over, as he has found a companion in Mana. And Mana, who had been trapped in a small hut her whole life, finds delight in even the simplest of things. Together, Yuta and Mana attempt to seek out more mermaids, trying to become normal humans again.

One day, Yuta and Mana meet Masato, a little boy who seems terrified of his mother Misa. It seems to Yuta and Mana that mother and son have a very unusual relationship. What happens when Yuta and Mana decide to discover the dark secret Masato and Misa are hiding? And what about those monster-like creatures that have been appearing?
