In a realm where humans, demihumans and oni clash in endless strife, the princess Saltorine "Sally" Aldike seeks out a man named Mikoto Kibitsu. As she roams the land, Sally uncovers truths long hidden by her bloodline—including that oni wield a force strong enough to erase humanity.
Fortune has granted Sally a counterforce: a peach‑shaped sigil that endows her with superhuman might, enabling her to vanquish formidable oni effortlessly. Yet she shuns bias against humans, demihumans or oni alike, holding that harmony among the three races is possible.
Mikoto, who shares Sally"s gift but wields it with greater skill, pursues a darker aim. He intends to exterminate every oni, leaving nothing behind. The clash of their powers will decide whether the world ends in peace or total ruin.
