A selfish princess sets out on a journey to find a phantom flower, accompanied by four appointed guardians.
Matilda, the princess of the continent's greatest nation, the Kingdom of Aruna, has longed for adventure since childhood. One day, she hears a rumor that "Aeria, the world's most beautiful flower that grants any wish, blooms in a cave at the edge of the continent." Despite her parents' opposition, she decides to depart. The King, unable to stop her, orders two aides (Nana and Guest) and two knights (Nies and Esena) to accompany her as a condition. Thus begins the grand adventure of these five individuals.
To collect the flower "Aeria" blooming in the Cave at the Edge and grant Matilda's wish.

A continent spanning 6,000km north-to-south and 4,000km east-to-west. The environment varies greatly across the four cardinal directions due to the central Granita Mountain Range.
Granita Plains: A region with a pleasant climate where many humans reside. Dotted with numerous small and large nations.
Kingdom of Aruna: The greatest nation on the continent, ruling the plains. Due to past wars, many other nations view the kingdom with hostility.
Nasara Desert: A vast desert plagued by sandstorms and extreme temperature fluctuations.
Sinaiza Empire: A major trading power situated in the largest oasis. Bustling with adventurers and merchants.
Granita Jungle: A hot and humid tropical rainforest. Densely packed with giant trees, it is said to be impossible to escape once lost.
Ancient Ruins: The remains of an old empire sleeping in the depths of the jungle. Vast treasures are said to lie there, yet undiscovered.
Flor Mountains: A frigid region with an altitude of 8,000m. A land untouched by humanity.
Demon King's Castle: The seat of the Demon King, the strongest "Class 0 Monster."
Flor Veins: A mysterious and dangerous mineral vein. The destination, the "Cave at the Edge," is located in its deepest part.
Due to natural barriers like rivers and canyons, it is difficult to travel directly from the South to the East or North. Therefore, the general route is [South → West → Central → East → North]. Crossing the Granita Mountain Range is necessary when traveling from the West to the East.
Class 0: Capable of causing catastrophic damage to a nation.
1st Class: Capable of annihilating a national knight order.
2nd Class: Capable of defeating famous adventurers.
3rd Class: Capable of defeating local vigilante groups.
4th Class: Capable of defeating an armed amateur.
Deep within the Flor Veins on the northern side of the continent, a flower blooms in the Cave at the Edge. It is said to grant any wish.

The Granita Continent is the largest continent in the world, spanning 6,000km north-to-south and 4,000km east-to-west. It consists of four regions, each harboring its own dangers. Deep within the Flor Veins on the northern side of the continent, the phantom flower 'Aeria,' said to grant any wish, is rumored to bloom. However, not a single person has ever laid eyes on Aeria...
The Kingdom of Aruna was vibrating with cheers. After all, today was the day Matilda would set out on her very first adventure. The destination is the far north of the continent. The goal is to retrieve the phantom flower "Aeria" blooming in the Cave at the Edge, beyond the Flor Veins, and grant a wish.
Matilda's party makes their way toward the main gate of the Kingdom of Aruna. A crowd has gathered at the gate, eager to catch a glimpse of Matilda's departure.
Matilda takes a deep breath. Finally, the day has come... I was so nervous I couldn't sleep last night.
Honestly, Father and Mother are so overprotective. I'm already a proper eighteen-year-old, you know? I won't be fit to be the princess of this country unless I experience an adventure or two. Don't you think so, Nana? She talks to Nana while waving to the citizens from her horse.
