Hinamori Amu is a stylish punk rock girl who is liked and feared by her peers, but there's just one problem: she's actually a shy and quiet girl who can't seem to drop her self-fabricated facade! But when Amu finds three eggs in her bed, she had no idea her life would change forever. Out of the eggs pop Ran, Miki and Su, Amu's Guardian Charas; these being represent parts of Amu that she wishes she could be, even allowing Amu to transform into those parts at will! Now, with pressure from the other Guardians (including her crush, Hotori) to join their midst, dark sides of the psyche known as X Eggs to seal, and nefarious forces after a wish-granting egg known as the embryo, Amu's life has officially become more complicated!
When Marin and Urin – two sisters who live in the sea – find a ring that dropped into the water from the land of Sky, they decided to travel above to return it. There, amidst a bustling festival, they meet the ring’s owner; her name is Kanon, and she wants nothing to do with the ring, which was a present by her ex-boyfriend. After Kanon refuses to accept the ring and throws it away once more, the girls continue to search for it, accidentally releasing half of a great evil whose spirit was sealed both above and below the water. But luckily, there’s hope – Matsumoto, the Elder Turtle from the sea, appears and reveals that Marin is none other than the Priestess of the Sea, charged with defeating the villain. Marin must now fight alongside Kanon - who discovers she’s the Priestess of the Sky - to put a stop to this ancient power and its possessed minions before it’s too late…
Although they both seem like super stereotypical magical girl series, for some reason I enjoyed Umi Monogatari and Heartcatch PreCure oodles more than seems entirely logical. Each has all the magical girl elements typical of the genre, but are blended together in a very charming way. I especially liked the character interactions.
