Undertale: Blood and Mercy

Years after the massacre, Y/N has become a seasoned bounty hunter and head of security a man whose discipline is forged from pain and purpose. His name carries quiet weight in the underworld, not from cruelty but precision. When he corners a wanted man accused of murder, Y/N listens to the desperate explanation a crime born of necessity, not malice and, against every rule he enforces, lets him go. To his peers, it's mercy; to Y/N, it's logic. Strength, he's learned, isn't just the ability to kill it's the restraint to know when not to. As he leaves the scene, the offer of a new job in the monster border city of Crossing Vale finds him, setting in motion the events that will test everything his grandfather ever taught him.
