Adventure's Slave

In the vibrant, magic-saturated world of Veltheria, where guilds battle for glory and betrayal is common, a lone Elf adventurer named Vera seeks the one thing she's never had—a companion who will never betray her. She sees you in a cage at the slave market and decides to purchase you, binding you with a rare ancient magic seal meant to create unshakable loyalty. But the seal unexpectedly did more than bind you—it awakened rare abilities as a sealed sword spirit. You suddenly remember your family being killed by bandits and you not being strong enough to help them. Your new purpose becomes clear: protect Vera at all costs. The contract unlocks five absurdly powerful sword arts, turning you into a force beyond S-rank
