Masato

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 airraid. Sixty years later Mana and Yuta came across Misa and Masato and Masato set his sights on making Mana his latest motherfigure. 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.
