Finished

うみものがたり ~あなたがいてくれたコト~

Marin and her younger sister Urin are seafolk living peacefully in the ocean. One day, they discover a beautiful silver ring that has fallen into the sea. Determined to return it, Marin convinces a reluctant Urin to journey to the surface world, where they meet the ring's owner, a girl named Kanon. Kanon, heartbroken after a recent breakup, rejects the ring and discards it once more.

While searching for the discarded ring in a forest, Urin accidentally breaks a seal on a stone coffin. This reckless act releases Sedna, a great evil long imprisoned. An elder turtle named Matsumoto emerges, revealing Marin's destiny as the Priestess of the Sea. To confront the rising darkness, she must unite with the Priestess of the Sky. During a battle with Sedna's minions, Kanon discovers she possesses this very power, forging an unlikely alliance to save their worlds.
