うみものがたり 〜あなたがいてくれたコト〜

Marin and Urin, two mermaid sisters, live in the sea and dream of visiting the land. One day, they discover a ring that has fallen into the ocean and decide to venture onto land to return it to its owner.

They meet Kanon, a high school girl who threw the ring away after a painful breakup. Believing Kanon still harbors feelings for her ex-boyfriend, Marin sets out to find the ring in the forest. However, Urin accidentally breaks a seal near a shrine, unleashing a mysterious force that threatens both the human and mermaid worlds.
