is a Japanese anime series, directed by Yuu Kou and Junichi Sato and produced by Zexcs. It began airing on Chubu-Nippon Broadcasting on June 24, 2009.[1] An unaired episode was featured in the final DVD volume, released on March 26, 2010.[2] The anime is based on a pachinko game manufactured by Sanyo Bussan.[3]
The story centers on Marin and Urin, two “pure” mermaid sisters who live alongside the fish in the sea, but yearn to be in the world beyond the water and above ground. One day, a beautiful ring falls in the middle of the sea, and Marin and Urin retrieve it. The two decide to leave their waterbound world for the first time to deliver the ring. After an arduous journey, they come across an isolated island where a high school girl named Kanon lives. Urin accidentally unleashes Sedna, a powerful entity sealed a long time ago on the island and in the sea, and the only ones who can defeat her are Marin and Kanon, as priestesses of the sea and the sky.
Mentored by the Elder Turtle, the girls fight various sea creatures that Sedna has transformed into monsters, but Urin's growing jealousy of Kanon and inability to fight on her own draws Sedna to corrupt her. Taking the role of priestess of darkness and Sedna's host body, Urin releases Sedna's sea half to restore her full strength and declares Marin and Kanon her enemies. The despair from losing her sister and her own inability to cope with darkness causes Marin to lose her powers. Kanon similarly despairs over her fear of making meaningful connections with people and driving them away, in particular her distant ex-boyfriend, Kojima.
While Kanon works to develop her powers and help Marin regain hers, the Elder Turtle is adamant that Urin is a lost cause and focuses on stopping Sedna by force, as previous priestesses had done, even if it kills her host. After confronting her own insecurities, Kanon helps Marin come to terms with her fear, and she regains her powers. They are determined to save Urin, but Sedna absorbs their magic and destroys the stones they use to transform. Confronted with Sedna's darkness, Marin and Kanon realize that Sedna is actually the combined sorrow the islanders committed to the sea, afraid to face what was in their hearts--she's not evil, but a necessary part of humanity. With this knowledge and the experience gained from their journey, Marin and Kanon help the islanders accept Sedna back into their hearts, freeing a remorseful Urin and letting Sedna disappear peacefully. Marin and Urin soon return to the sea, but Kanon will never forget them and admits to Marin that she loves her.
Two manga adaptations of Umi Monogatari were serialized in two different magazines by different publishers. The first one, with the title Umi Monogatari ~Anata ga Ite Kureta Koto~, follows the same story as the anime. The second, titled Umi Monogatari: Minna Aishiteru! (Sea Story: Everyone, I love you!), has a yonkoma format and follows Marin and Urin's experiences on the island.
The first manga, illustrated by Akira Katsuragi, was serialized in Mag Garden's Monthly Comic Blade magazine. The second manga, illustrated by Tonmi Narihara, was serialized in Futabasha's Comic High! magazine.
