In a peaceful kingdom shaped by the Kinoko, a mushroom god as ancient as life itself, a lunar eclipse unleashes sudden chaos: creatures transform, forgotten legends awaken, and the six divine diamonds, once set in the sacred crown, scatter to the far corners of the world.

Ciruela, a pure‑hearted teenager, must recover them in less than two months to prevent darkness from taking over. Joined by Kilou, her little koala newly gifted with speech, and Kimino, an elf with a mysterious past, she rides Fégor, a horse turned dragon, through diverse biomes. Together, they encounter remarkable peoples and face a relentless witch determined to stop them, while a hidden benefactor watches over them from the shadows.

A journey filled with emotion, discovery, and danger, where each recovered diamond brings Ciruela closer to saving her world… and those she loves.
