This swordsman hired by the Merchantry uses Final Strike, a powerful attack that comes last in the action order. Watch out for his Carotid Slash -- it lowers M. Def.
The Merchantry Blade is an enemy in Bravely Default. Its Carotid Slash ability reduces the target's magic defense, and its Last Strike ability deals heavy damage, but is only performed at the end of a turn. Exploiting their weakness to Lightning makes for an easier victory.
