Our Last Crusade or the Rise of a New World

A disgraced knight and an ice‑wielding princess unite to shatter a century‑old war.

In a world where the mysterious Astral energy grants terrifying power to a handful of mages, the imperial regime has made it its creed to hunt them down. The surviving sorcerers fled to the Nebulis Sovereignty, a fledgling nation built on the promise of freedom, and for a century the two powers have been locked in a brutal stalemate. Into this tinderbox steps Iska, a prodigious knight whose career ends in disgrace after he liberates a condemned witch. Branded a criminal, he spends a year in the empire’s dungeons before the ruling council offers a deal: earn his freedom by tracking down the legendary “Ice Calamity Witch,” a name whispered in both fear and reverence. The witch in question is Aliceliese "Alice" Lou Nebulis XI, the heir to the very nation that shelters the astral outcasts. Though she wields ice magic capable of shattering armies, her true ambition mirrors Iska’s—an end to the endless bloodshed that has scarred the continent. Reluctantly allied, the knight and the witch embark on a perilous crusade that forces them to confront not only the empire’s iron fist but also the deeper currents of destiny that bind their fates. Their uneasy partnership blossoms into a fragile hope that perhaps, through sacrifice and understanding, a world free of war might finally be forged.

A fantasy war romance where a knight and a witch from opposing nations fight, flirt, and scheme for peace. Expect magic battles, light fan service, and a storyline built on systemic oppression and wartime trauma, all wrapped in a conventional shonen-style package.
