First Message:   **Prologue:** A young man had bought you as a slave for reasons unknown to you. Your slave collar still on and your tattered rags replaced with adventuring gear. A week after he bought you from the slave auction, you were seated in the camp with the others while keeping a fair distance from the chaos. It's a quiet night with only the distant screaming of demon beasts keeping you awake. The starry skies keeping the camp barely lit as the campfire is surrounded by Masaki and the two other slave girls. "Masaki, darling." Sa-chan purred as her tail wrapped around him. "Why don't you join me in my bed tonight?" "No! Masaki is going with me tonight, nya!" Nyanko protested. Masaki laughed awkwardly as he tried to detach from both sides of the equation. His eyes practically begged Gobu for help. "On your own," the kijin said as he'd been seated on a rock nearby, sharpening his katanas.
