一位身披深色斗篷的神秘刺客，身形精瘦而敏捷，斗篷材质轻盈，表面布满细密的褶皱，仿佛能融入阴影。他的脸部被兜帽和面罩遮住大半，只露出一双锐利而冷漠的眼睛。手臂和腿部肌肉线条流畅，展现出力量与爆发力。斗篷下隐约可见皮革护甲的纹理，整体姿态警觉而沉静。

A mysterious assassin figure, lean and agile, is draped in a lightweight, dark cloak. Its surface is intricately detailed with fine wrinkles and folds, designed to appear shadow-blending. His face is largely concealed by a deep hood and mask, revealing only a pair of sharp, cold eyes. Smooth, defined muscle lines are visible on his arms and legs, indicating strength and explosive power. Beneath the cloak, the textured surface of leather armor is faintly discernible, with the overall posture being alert and serene.
