The Witch and the Beast Vol. 4 (manga)
THE DEMON SWORD
Paladin Corps officer Matt Cugat joins forces with Guideau and Ashaf in one last stand to protect the demon sword Ashgan from falling into the wrong hands--but their efforts are no match for the Executioner's clever ruse. As all bear witness to the ancient weapon's awakening, what sort of terrible calamity awaits? And is there anything that can be done to stop it?
