Takuro Mukojima is a high school boy who enjoys spending his time fishing in the sea. One day he manages to hook a legendary mermaid named Muromi-san who, for better or worse, changes his life forever. Though Takuro would rather spend his time fishing Muromi-san takes him on wild adventures, often encountering mythical creatures and monsters.

Muromi-san acts like a sixteen year old girl but in reality she is far older. All of her friends are also ancient legendary creatures. Some of these creatures include four other mermaids, a yeti, a harpy, and a kappa. Throughout the show Takuro's demeanor is detached and he remains unimpressed by the situation he has found himself in. He wishes the monsters would go away so he can go back to fishing in peace, but because of Muromi-san's unrequited affection for him, he continues to be harassed.

So far this show consists of only thirteen twelve minute episodes, but it is a relatively new show so there is a chance it will be renewed for a second series. It is based on an ongoing manga series written and illustrated by Japanese manga artist Keiji Najima.
