Left-hand Man

Left-hand Man is the assistant to Yan Sis, along with Right-hand Man.

Background
Left-hand Man is presumably born more than ten thousand years before the current timeline, and has assisted Yan Sis along with Right-hand man for a very long time. For unknown reasons, he lost all the flesh and skin on his limbs, with only his face retaining the orange skin shared by all demons.

Personality
A notable trait of Left-hand Man is his pedophilic nature, as shown when he blushed while commenting on Xi Sha's prepubescent appearance, and when he attempted to accompany Xi Sha to the human world.

Appearance
Left-hand Man is always seen wearing a black cloak that covers up his entire body. As a demon, he possesses orange skin, and has been shown to possess skeletal limbs. It is unknown whether his torso retains flesh and skin or not. During his infiltration in the human world, he wore a black hoodie and black pants, as well as wrapped his entire body in bandages except for his eyes, which he covered up with a pair of shades.

Abilities and Powers
Left-hand Man seems to possess no combat abilities. However, he does possess abilities to observe locations that transcend dimensional boundaries, making him great for observation and reconnaissance purposes.

Left-hand Man's techniques

 * EyeofDimensions.pngEye of Dimensions (异界之眼): Left-hand Man is able to create portals that allow him to observe other dimensions. He used this technique to observe Che Yongtai and Xi Sha while they were in the human world, as well as observe Ye Yan and Che Yongtai during their duel with Deng Yuankui and An Ningxue in a separate dimension. This technique takes up a lot of energy and concentration if it transcends dimensional planes, as Left-hand Man was only able to keep it up for a few seconds when observing the human world from the Underworld, while he was able to keep it up for a relatively long time while observing the duel.
 * Voice of Dimensions (隔界传音): Left-hand Man is able to speak to an individual of his choice in a different dimension through the use of this technique, but at the cost of ten years worth of his lifespan. If the line of communication is forcibly interrupted by the receiver, it will double the cost, making him lose twenty years of his lifespan as well as severely internally injure him.
