The story of a Beast King intent on protecting monsters--and his human companion.

Dungeon diving is a way of life for adventurers seeking hidden riches and powerful monsters to defeat. Tina, a brash young explorer, is eager for glory--but her reckless pursuit of treasure leaves her gravely wounded. On the brink of death, she's stunned when a monster comes to her aid.

Her savior is no ordinary creature. He is the fabled demon known as the Beast King Garon--still very much alive despite legends of his demise. In exchange for saving her life, Garon makes one request: Tina must join him on his journey to heal wounded monsters. But can an adventurer raised to slay monsters learn to heal them instead?
