Plot
Takurō Mukōjima is a boy angler. He lands a ningyo (Japanese mermaid) by the name of Muromi-san and develops rapport with both her and her friends. The series title in English is Muromi-san and the Legendary Beasts. Muromi physically appears as a 16-year-old, however in reality, she is an ancient legendary creature. Muromi and her sisters are both guardians of the Earth and much older than they appear. "Takkun", as Muromi calls him, is a high school student who does not have a lot of motivation or care for all the attention Muromi gives him, yet he still ends up getting involved in Muromi's adventures. There are a number of legendary monsters Takkun meets and almost gets eaten by during their adventures.
An innocent mermaid who also speaks Hakata dialect. She calls Muromi "sis (おねえたん, onee-tan)." Loves animals, and is good friends especially with dolphins.
A high-handed mermaid who has huge breasts. Later, she awakes to love for Muromi, although Muromi does not feel the same way, and later becomes a masochist.
A cryptid in Himalayas. Unlike the general reputation, it is cute, quiet and diligent. It is shy, but is friends with Muromi. It hates being pulled by its ears.
A childish, forgetful bird-girl who lives with and takes on Yeti and often pounces on mermaids. She also has a really short memory, forgetting everything important after walking three steps.
An owner of the Ryūgū-jō, a legendary undersea palace. However, the Ryugu-jo went bankrupt and she is reduced to a part-time worker in human world now.
A Kappa friend of Muromi. Like other kappa, he is skilled in medicine and raising cucumbers. He dislikes humans because they killed his older brother (his mummy is the one in the Zuiryū-ji temple in Osaka) but takes a liking to Takurō.
