Mermaid Saga tells the tale of Yuta, an immortal who has been alive for five hundred years, who is wandering across Japan searching for a cure and meeting others whose lives have also been ruined by mermaid flesh in the process.

A wind has swept the Earth taking all the memories from everyone. No one knows who they are, how to speak, or how to use the tools of modern civilization. Two years later, a young man who has been re-educated travels across America on a mysterious journey.

Two cops, Taki, a human male, and Maki, a female demon, are assigned to protect a diplomat who will help secure another treaty.

可爱的动物，明亮的画面，短小精悍的故事。不要被它小清新的外表所蒙骗，动物们每集最后不被弄的支离破碎，导演们是不会善罢甘休的。强烈的反差让这部动画显得非常奇特，颇具黑色幽默。可爱外表的动物，风和日丽的开头，但结尾总会大逆转，跌破观者的想象力。各种动物轮番出场，各具特色的性格，各种离奇的死亡方法。披着小清新皮的重口味，给你绝对的视觉冲击。
