A peaceful kingdom, ruled by the young Princess Louise, is suddenly overrun by monstrous creatures known as Armed Penguins. These bizarre, aggressive beasts attack without warning, driving the kingdom to the edge of annihilation. The kingdom's defense relies on Guillaume, a magic technician, and his elite forces who wield Modern Magic, a refined system of combat sorcery that incorporates the pinnacle of scientific technology. Despite their advanced techniques and strategic prowess, the kingdom's military is overwhelmed and unable to repel the onslaught.

As despair takes hold of the citizens, a prophecy from a thousand years ago begins to unfold. Alvira, the legendary great mage of antiquity, is revived in the kingdom's hour of need. With the fate of the nation hanging in the balance, Alvira unleashes the most powerful Ancient Magic against the swarming Armed Penguins. However, the outcome of this clash between prehistoric sorcery and modern-day monsters is far from straightforward, and the revival of this ancient mage introduces its own set of complications and unexpected consequences.

The story is driven by the contrast between the highly technical, science-based Modern Magic and the raw, overwhelming force of Ancient Magic. Key characters include Princess Louise, the determined young ruler fighting for her kingdom; Guillaume, the capable but outmatched magic technician who represents the pinnacle of current magical science; and Alvira, the enigmatic and immensely powerful mage from a millennium ago who must adapt to a world that has drastically changed. The narrative arc follows the kingdom's desperate struggle for survival, the unexpected arrival of a legendary savior, and the chaotic aftermath of mixing ancient power with a modern conflict.
