■Currently, Volumes 1-4 are available from Hero Bunko.

Young Holy Knight Ashle, tasked with recapturing sacred relics, encounters Sion, a Night Demon Princess trapped in an eternal night, and Izma, the forgotten ancient Tsuchigumo King, in the ruined and desolate Kingdom of Ignash. The spark ignited by their encounter becomes a flame that moves history. Facing powerful foes──Overlords, and a sprawling grand conspiracy, the heroes fight back, relying on their own will and its manifestation, the 《Spindle》. And where will the multifaceted intertwining romance eventually lead?

When the radiant light of the Holy Sword: 〈Rose Absolute〉 illuminates their arduous path, will the mystery of the Brilliant Soulspinner: 《Weaver of Souls》 be unraveled?

This is a fantasy, and at the same time, a story that delves into the mysteries of the 《Soul》.
