In ancient China, during the Warring States period, a former servant named Xin rises through the ranks with a dream: to become the greatest general under the heavens. Fighting alongside King Ying Zheng of Qin—who seeks to unify China and end the chaos—Xin leads his own unit, the Fei Xin Force, onto the battlefield. With power reclaimed from the influential Chancellor Buwei Lü, King Ying Zheng begins laying the groundwork for a new, unified legal state with the support of key allies like strategist Changping Jun and legalist Li Si. As Qin launches a campaign to seize new territory from the state of Zhao, their advance is halted by the brilliant strategist, Li Mu. In response, Changping Jun devises a bold plan: to bypass Zhao's defenses and strike at the key city of Gyou, near Zhao's capital. To carry out this risky maneuver, a powerful coalition army is formed—led by the tacticians Ou Sen (Wang Jian), Kan Ki (Huan Yi), and the warrior queen Yo Tan Wa (Yang Duanhe). Joining them are the next generation of Qin commanders: Xin's Fei Xin Force, Mou Ten (Meng Tian)'s Gaku Ka Unit, and Ou Hon (Wang Ben)'s Gyoku Hou Unit, each operating independently. The fierce battle for Gyou begins, as the future of Qin's unification hangs in the balance.

Melphiera Marchalrayd, the daughter of a count, dedicates her time to researching the culinary possibilities of monster meat—a peculiar endeavor started by her late mother. By teaching the people of the Marchalrayd lands to prepare such exotic ingredients, Melphiera hopes to help stave off famine. Unfortunately, her unique tastes and intimate knowledge of monsters have led to her social isolation: few nobles interact with her willingly, disdainfully calling her the "Voracious Villainess." When a monster attack erupts at a royal banquet—where Melphiera has been sent to find a husband—Aristide Rogier du Galbraith, the younger brother of the crown prince, leaps to her aid. Due to his terrifying skill in slaying monsters, Aristide has earned the title of "Blood-Man Duke." Charmed by Melphiera's fearlessness and intriguing culinary prowess, Aristide soon declares his intent to propose. Together, Melphiera and Aristide, high society's most eccentric couple, strive to see beyond the cruel rumors and encourage each other's fascination with monsters and the art of preparing them.

In a ritual, the Goddess bestows upon 10-year-old children a "class" that shapes their entire future. As the son of the legendary Sword Princess Fara and Archmage Leon—two of the highest-ranked individuals in their respective classes—Arel seemed destined for greatness. Unfortunately, he is branded as classless and thus unable to naturally inherit any kind of specific skill.

Eager to test his unprecedented skills even more by finding stronger opponents, Arel sets out to defy the limits imposed upon him and prove that perseverance can surpass even divinely appointed talent.
