But, in the world of anime, where we are only limited by our imagination, mermaids come to life in stories full of magic, drama, and joy. So, without further ado, let us introduce you to the best mermaid anime of all time.
Best Mermaid Anime of All Time!
There are tons of anime featuring mermaids out there. Here's a list of 14 best mermaid anime ever:
14. Valkyrie Drive: Mermaid
This mermaid anime series revolves around girls who have been infected with a mysterious virus known as the A Virus (Armed Virus). This is a shoujo, ecchi mermaid anime with mild nudity, elements of sex, and romance. Valkyrie Drive is about a teenage girl, Mamori, who has a very timid and shy nature at school. She is always teased and bullied because of her last name, Tokonome, which can also be read to mean virgin.
At the school, these girls are divided into two classes. There are Extars, who can transform into weapons when sexually aroused. There are also Liberators, who have the power to wield an Extar's weapon form, known as Liberator Arms, through a process known as Drive. These girls are brought to separate islands to spend their days completely isolated from the rest of the world. The island has observers, authorized by the government and Organisation AAA.
Mamori, our protagonist, is an Extar whose transformation is a large curved sword, though she later gains the power to transform into a double-bladed spear through the Valkyrie Effect. Unknown to herself, her power level is far greater than other mermaids. Later, Mamori is partnered with Mirei, and we follow Mamori on her adventures on the Mermaid Island after she awakens her inner powers all due to this one passionate kiss from Mirei.
13. The Prince and The Coral Sea
The next on our list was a simple tale of a prince and mother nature. Sango no Umi to Ouji is also known as The Prince and The Coral Sea. This mermaid anime is a tale about a little prince who wants to do something about the destruction of nature, the sea, coral, and life around him.
The message of the movie is basically how humans should take responsibility for the destruction of mother nature that happens because of them. Our protagonist meets a cute mermaid on his adventures who helps him understand more about the seas. The plot of this 30-minute movie is pretty straightforward, though it is still enjoyable to some extent.
12. Namiuchigiwa no Muromi-San
Takuro Mukojima is an angler boy. Teenager Takuro Mukojima spends his time fishing alone at the pier. One day, he catches something…or someone? It’s not a fish, but he lands a “ningyo,” a Japanese mermaid named Muromi-san. This happens because Muromi and her mermaid friends decided to see the human world, the world above the sea.
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 doesn't have a lot of motivation or care for all the attention Muromi grants him. He still ends up getting involved in Muromi's adventures. There are a number of legendary monsters Takkun meets and almost gets eaten by as their adventures unfold.
Muromi-san is a bit slow on the uptake, a bit crazy, a bit of a drunk, and very much unaware that she's a mermaid. The series title in English is Muromi-San and the Legendary Beasts. The mermaid anime is an amazing watch if you’re looking for a slice-of-life comedy with no overarching story elements as such.
