Anime: Umi Monogatari
Kanon, Urin & Marin

Originally a pachinko game series, Umi Monogatari (Sea Story) was given an anime adaptation by ZEXCS in the summer of 2009 with the subtitle Anata ga Ite Kureta Koto (That You Were There for Me). It was directed by Junichi Sato.

Under the sea, two mermaid sisters by the name of Marin and Urin are enjoying their life devoting full time to floating. One day, a ring falls from the surface and into Marin's hands. She wants to find the ring's owner and return it, and takes Urin along for the ride. It's then that they run into Kanon Miyamori, a young priestess who's about to get involved in a series of events neither she nor the sisters could've planned for when Urin ends up unleashing Sedna, an evil force intent on shrouding the world in darkness. This is what prompts Marin and Kanon to become the Priestess of the Sea and Sky.

Umi Monogatari is unusual among Magical Girl Warrior shows in that the focus is more on emotional development of the characters, the fights are fairly long, the girls' mentor is completely wrong about some things, most of the music is gentle piano music, and the revelation of what the Big Bad really is allows for a conclusion that's more true to life than most shows of this nature.

Tropes in Umi Monogatari include:

  • Absurdly Youthful Mother: Miyako, Kanon's mother. She looks young enough to be one of her daughter's friends, and has the personality to match.
  • All-Loving Hero: Marin. Her hug will save the world.
  • Alpha Bitch: Oshima, though she has Hidden Depths.
  • An Aesop: Everyone has darkness in their hearts. That's normal, and we must learn to accept it, not cast it out.
  • Anticlimax: There is no final battle, as Sedna's nature and the accompanying sorrow is accepted by the islanders rather than sealed away. There is, however, an emotional battle to save Urin.
  • Arc Words: "I love you!"
  • Aura Vision: Kanon has an "evil aura" that everyone can see and comment on.
  • Balance Between Good and Evil: This turns out to be a crucial part of the series, as the islanders' unwillingness to accept and deal with the sorrow in their hearts created Sedna. In the end the darkness is accepted by them and becomes one with the light.
  • Bare Your Midriff: It's standard for Mermaids, but Oshima and Miyako are prone to this as well.
  • Bittersweet Ending: Kanon and Marin defeat Sedna, but have to separate since land and sea people are not supposed to be together. It is hinted that Kanon will keep looking for Marin.
    • In the DVD special it becomes clear that Kanon keeps longing to meet Marin again. She even seems to get her wish for a while, which makes things even more bitter.
  • Blade on a Stick: The girls are told that to seal Sedna away they must pierce her with the Spear of Light. We never get to see it.
  • Bonus Episode: The bonus 13th episode in which Marin and Kanon have a near-encounter after the series.
  • Brainwashed and Crazy: Sedna does this to sea creatures and eventually Marin and Kanon's friends.
  • Bratty Half-Pint: Urin is this mainly towards people on land.
  • Butterfly of Death and Rebirth: Eerie blue butterflies show up the night of the eclipse. Urin grows butterfly wings after hatching from a cocoon.
  • Cannot Spit It Out: Kanon doesn't confess that she likes Kojima because she's afraid he'll reject her.
  • Can't Catch Up: Kanon struggles with this, feeling inadequate at times.
    • Urin does likewise to a much greater extent, as she can't fight at all, but wants to very badly.
  • Catchphrase: "I love you!", said by Marin to almost everybody.
  • Cerebus Syndrome: Sets in around episode 6.
  • Clingy Jealous Girl: Urin, towards Marin. Justified since she's a little girl.
  • The Corrupter: Sedna.
  • The Corruptible: Various sea creatures, but this trope is most present in Urin.
  • The Corruption: Sedna's influence, signified by too-bright or red eyes.
  • Dark Is Not Evil: Kanon's evil aura doesn't make her evil; it grants her immunity to Sedna's evil.
    • This is the point of the shrine maiden's song, as darkness and light must coexist.
    • In the end, Sedna fits this, as she was created out of accumulated sadness in people's hearts.
  • Darkest Hour: The end of episode 11. Marin and Urin try to fight Sedna, but have their powers drained from them. The episode closes with them sprawled on the ocean floor, near death, as Sedna's darkness flows into their bodies.
  • Defrosting Ice Queen: Kanon.
  • Designated Love Interest: Kojima, with whom Kanon doesn't even have a fraction of the chemistry she has with Marin.
  • Disability Immunity: Kanon's evil aura protects her from Sedna's darkness.
  • Does Not Like Shoes: The mer-people go barefoot.
  • Drowning My Sorrows: Not in alcohol, but in a soothing song the island priestess sings; it even calms Marin out of her Heroic BSOD. And the ocean. The islanders' tears of sorrow and ritualistic stones falling into the sea formed Sedna out of their grief.
  • Earn Your Happy Ending: Marin, Kanon, and Urin have to go through a lot while fighting Sedna. In the end they don't defeat her, but accept the sorrow back into their hearts and those of the islanders, melting the darkness with light.
  • Everybody Lives
  • Face-Heel Turn: Urin turns evil halfway through the series.
  • Fantastic Racism: Urin's not exactly pleased with the people on land.

  • Foil: Marin is outgoing and positive, while Kanon is quieter and gloomy.
  • Gainaxing: Oshima, only to be quickly outdone by Marin.
  • Genki Girl: Kanon's mom, Miyako.
  • Greek Chorus: The shrine maiden comments on the plot at times.

  • Humanity Ensues: Sea creatures Sedna corrupts gain human forms.
  • Incorruptible Pure Pureness: The Elder Turtle thinks Marin is this, and strives to protect her from the darkness. Instead she falls into it.
  • Iyashikei: This anime is about accepting your inner darkness.
  • Innocent Fanservice Girl: Marin's skimpy clothing is commented on when she first comes ashore, though Kanon eventually gets her and Urin to wear something a little less revealing.
  • Kiss of Death: Sedna's soldiers try to kiss Kanon to suck out her evil soul.
  • Know-Nothing Know-It-All: The turtle mentor has shades of this; not only is he wrong about which priestess will fall into darkness, he doesn't comprehend what Sedna truly is and gives wrong information as a result.
  • Larynx Dissonance: Kojima sounds very girlish.
  • Last Episode Theme Reprise: Inverted, as the theme plays at the beginning of the last episode in a more somber tone as Marin and Kanon are near death.
  • Leitmotif: The shrine maiden's song, as well as Sedna's theme.
  • Lonely Piano Piece: This constitutes a lot of the music in the series.

  • On the Next: Next episode previews generally have Marin talking about sea creatures.
  • On The Next Episode Of Catchphrase: Marin's "Everyone, I love you!"
  • Open Minded Parent: Two mermaids and a talking turtle staying at Kanon's house? No problem!

  • Playing with Fire: Kanon's power.
  • Power Dyes Your Hair: Kanon's hair becomes lighter and has a different shape when transformed.
  • Power Gives You Wings: Urin appears with a pair of butterfly wings after she awakens from a literal cocoon. In the final episodes the wings grow huge and colorful.
  • Power Makes Your Hair Grow: Marin and Urin get this when transformed.
  • The Power of Love: How Marin saves Urin.

  • Red Eyes, Take Warning: Averted with Kanon and the shrine maiden, but played straight with a corrupted Urin.

  • Sealed Evil In A Six Pack: Also Sedna; she has half of her in land and half in the sea.
  • Scenery Porn: Plenty of lovely shots of the seaside town in which the story takes place.
  • Sheathe Your Sword: Sedna is "defeated" by everyone accepting the darkness within them, not casting it away or fighting it.
  • Shoot the Dog: The turtle mentor lives by this, even telling the girls to take him down without hesitation should he be corrupted. His advice is wrong.
  • Shout-Out: To "The Little Mermaid", as Marin is warned that Urin will turn into sea foam once Sedna is defeated. She doesn't.
  • Sweet Dreams Fuel: The first half of the show, anyway.
  • Sugar Apocalypse: Seen in the latter half of the series.
  • Symbiotic Possession: In the second half of the series, Urin and Sedna's relationship works like this. Urin gets Sedna's powers, while Sedna gets her body.
