The Infinite Sky. The Infinite Earth. A continent that embraced all the world.
At its heart lay the Elven Kingdom of Maradian—a land of abundance and blessings,
a realm filled with dreams, compassion, love, and joy.

Using the "Interdimensional Transfer Device (Gate),"
a heretic from another world led an army of cursed dead to invade the human realm.
The fierce battle that followed ultimately ended in a hard-won victory for humanity.
The mastermind behind the invasion was vanquished
thanks to the efforts of the Crimson Princess Artesia (Asha) and Harukaze Sakura.

Having successfully quelled the rebellion in the Elven Kingdom of Maradian,
Harukaze Sakura returned to a peaceful life alongside Asha and her friend, Shibaame Yuzuha.
The remaining Gate was classified as a top-secret matter,
placed under the strict surveillance and protection of the Guild—or so it was believed.

However—

Peace did not last long.
An assault came from Kingdick, the Kingdom of Giants (Gigants),
a nation thought to have been destroyed.
An unprecedented crisis loomed over the human world once more.
