Japanese Title: 波打際のむろみさん

Plot
Takurō Mukōjima is an lonely angler teenager boy. One day, Takurō was fishing at the pier as usual, when he caught the big one: He lands a ningyo (Japanese mermaid) Muromi-san and has a chat with her and her strange friends. The entire title given to the series is in English "Muromi-San and the Legendary Beasts". Muromi is developmentally about 16 years old, but is actually a very old legendary creature, her sisters and she are guardians of the Earth. She is incredibly dense and crazy and has a drinking problem to top it off, she uses a shell-phone, and is instinctively afraid of birds and seals due to their love of fish. 'Takkun', as Muromi calls him, is a high school student who doesn't have a lot of motivation or care for all the attention Muromi wants to give him. But he still winds up getting involved in Muromi's adventures. There are a number of legendary monsters 'Takkun' meets since the time he met Muromi and almost gets eaten by: he's met Leviathan, a yeti, a harpie, a kappa, and more. Now every time Takurou goes fishing, Muromi appears and makes life interesting for him.
