Relics of Osai

Manomi Itsuki is a ten-year-old prodigy from Stonehart, Reggad—the Stone Nation built on endurance, discipline, and unwavering order. Raised in a family renowned for their unbreakable will, Manomi embodies the core values of his homeland: calm under pressure, sharp of mind, and deeply respectful of tradition. But his journey is not one of simple mastery. As the story unfolds, the very foundation that shaped him begins to crack. The calm he was taught to maintain is shaken. The discipline he inherited fractures. The certainty of Reggad's stone-solid worldview is tested by forces beyond his understanding. Manomi's arc is one of loss and reconstruction—a boy who must watch himself break, then choose to rebuild. Through hardship, doubt, and growth, he will reclaim the qualities that once defined him—not as inherited traits, but as hard-won wisdom. In doing so, he becomes the living embodiment of Reggad's ancient philosophy: "Stone breaks. Stone reforms. Stone remembers." This is the story of a boy who must lose himself to truly find who he is meant to become.
