Ryuji, a magicless boy born into a family of legendary warriors, has always been seen as weak and unworthy of his heritage. But everything changes when he encounters the Koori no Yumi (Bow of Ice), an ancient relic tied to his family's forgotten legacy.

Yet, what lies ahead for Ryuji—whether he can control this newfound power or whether it will consume him—remains a mystery, as the shadows of the future loom ever closer.
