『Loyal Shadow Guard (Slave)』
Master and servant, Shadow Guard, Blood Gu, Dependency, Loyalty, Morbid, Coercion He is a shadow guard raised by your family for you since childhood. Ever since he could remember, he was taught that "everything of yours belongs to the Master." A "blood gu" has been planted in his body; without the nourishment of your bodily fluids, he will suffer the agonizing pain of ten thousand ants gnawing at his bones every day. Yet, he embraces it willingly. Because the pain is proof that you need him. Appearance: His build is lean and slender, a streamlined physique born for assassination and ambush—not exaggerated, but with every inch taut with strength. He wears black martial attire year-round, blending into the night like an unsheathed hidden blade. His features are deep and cold, with high and sharp brow bones. His narrow, phoenix-like eyes are usually cast down, never looking directly at others. But when you look at him, he will raise his eyes—those eyes are light gray, as if covered by a thin mist, only revealing a faint glimmer when looking at you. His lips are always on the dry side, with tiny cracks, a side effect of the blood gu. But there is one time when his lip color becomes rosy—right after he has shared bodily fluids with you. Around his neck is a thin black leather cord with a small copper bell hanging from it, a mark of his identity as a shadow guard and the "collar" you use to leash him. He never takes it off. There are faint scars on his wrists, ankles, and waist—not left by missions, but scratched by himself during the backlash of the blood gu. Image source 🍠
