   Summary

   Yuuri Shibuya, the Maou of Shin Makoku, is yanked from his quick trip home for university finals and lands in the middle of Fódlan’s war—right in the path of Edelgard von Hresvelg’s revolution. His mere presence shatters Crests and Relics, making him the perfect symbol (and weapon) for the Empire’s cause. A political marriage to the emperor is proposed, Wolfram and his allies cross worlds to retrieve their king, and when Byleth awakens to a changed Fódlan, loyalties, hearts, and divine orders collide.
   “Crestless King” Yuuri stands between inherited lies and a future remade—whether he wants to or not.
