Tales of Hearts

Because of the great empire ruling over the whole continent, the people are in complete peace. They pass down fairy-tales such as "The Sleeping Princess of the Thorny Forest", "The Monsters that Eat Dreams", and "The Eventual Fading of the Black Moon". Though recently a disease that contaminates the heart called "Despil Disease" (デスピル病, Desupiru Byou?) has begun to spread.

Then the "Zerom" (ゼロム, Zeromu?), the monster from the fairy-tales that eats dreams is shown to exist, and they are beginning to eat into a person's heart, referred to as "Spiria" (スピリア, Supiria?) within the world. To be able to fight the Zerom, the humans' Spiria has created mysterious labyrinths in their hearts, known as "Spir Mazes" (スピルメイズ, Supiru Meizu?). Only with equipment known as "Soma" (ソーマ, Sōma?) can people go into these Spir Mazes.

The plot follows a young village boy known as Shing Meteoryte, and his adventure after rescuing a young woman named Kohak Hearts on the beach.
