Katia, a young farmer, leads a simple rural life in a remote corner of the Kingdom of Phoenix.

But that peaceful life goes to shit when she meets a cocky female guard accompanied by her half-sister on the streets of a border town.

The three girls don't yet know that their future is about to do a steep somersault in the air, crash to the floor with all their might, smash their foreheads through it, and collapse into an abyss of incredible adventure.

Lia, a powerful priestess with the title of Countess of the noble House of Hawk, and Katya's older sister, is unaware of this.

Nor does the fiery-haired Reina, the true target of the planned attack, suspect the impending threat.

And of course, Katya, an illegitimate bastard who was exiled to the farthest province of the kingdom as a child, is unaware of any of this.

As a result, a huge monster invades the city, and only thanks to the holy power of the High Priestess, the spawn of darkness was defeated.

Unfortunately, the victory comes at a high price, the wounded monster kidnaps the battle-weary Lia and retreats into the depths of the dungeon.

What should an ordinary girl who has devoted her life to growing zucchini and tomatoes rather than training with swords and magic do in this terrible situation?

Wasting no time, Katia sets off in pursuit.

All she has is a body hardened by hard work, fists trained in street fights, and a vow to save her sister.

An oath made not on the blood of the Hawk family, but on the blood of her long-dead mother, a troll warrior.
