Synopsis
Legend says that eating mermaid flesh grants eternal life. For Yuta, who has lived 500 years, and his friend Mana, that proved true. But most who attempt it either perish or turn into monsters. Fifty-five years ago, Towa Kannagi received mermaid blood from her sister Sawa to cure a deadly disease. Since then, Towa has kept a youthful look, except for her white hair and a monstrous arm. For years she has longed to fix her body, resorting to blood transfusions from dead young people with the help of the local doctor, Shiina. When Mana is mistaken for dead and brought in for Towa to use her blood, Towa learns Mana is still alive. How far will Towa go to heal herself? Can Yuta rescue Mana in time?
