In this gripping tale, 10th Muse finds Orion bird-watching in a national park, questioning his purpose and worn down by a crisis of meaning. The Muse proposes a new mission—using his talents to find missing people instead of hunting beasts. Their first case leads them to a crime scene with no clues, until Orion's keen senses point them to a local bar. A brawl ensues, but a tip leads them to a warehouse hideout. There, 10th Muse battles a demon while Orion rescues kidnapped children. Victorious but wounded, Orion finds a renewed sense of purpose—though at a personal cost.
