Y'Shari

Y'Shari is an ancient demon who is recognized as the King of Qin'guang Valley and former co-ruler of the Underworld with Xi Sha.

Background
Y'Shari is an ancient demon who has lived for thousands of years through reincarnation. Throughout his life, he has been challenged by countless people, all of whom he killed using their own techniques. More than two hundred years ago, he was the lover of Xi Sha's previous incarnation's, who he ruled the Underworld together with.

He was eventually sealed away by Yan Wen almost two hundred years ago, who used the Yellow Spring Demon Seal to seal him in a stone statue along with his follower.

Personality
Y'Shari is deeply infatuated with Xi Sha. Since his liberation, he repeatedly expressed his desire to reunite with Xi Sha and "join their bodies and soul". For the sake of gaining her affection, he is even willing to compromise by living together with Ye Yan, her crush, if it means she can requite his love. However, he is not above mind controlling his former love into loving him when she adamantly refuses to reciprocate his feelings.

Y'Shari has demonstrated a domineering and bloodthirsty attitude since his introduction. He repeatedly resorts to violent killing as a solution to problems, even if there are options that do not involve bloodshed. Additionally, when being refused by someone, Y'Shari prefers to mind control them into obeying him.

Y'Shari is also sadistic and arrogant. The reason Y'Shari is most skilled at using another person's techniques to kill them when challenged is because he believes crushing their pompous pride and confidence and leaving them with only despair and humiliation is the only appropriate punishment for offending him.

Appearance
Y'Shari is a fair-skinned man with long, spiky shoulder-length black hair and dark red eyes. He wears a black tailcoat with red markings on the left side, and a pair of black pants and black shoes. He has a tattoo on his back consisting of a cross with a crescent facing up, which is the same design as the emblem of the necklace he wears.

Abilities and Powers

 * Bloodbath Tide (血吸潮): By holding out his hand, which emits red energy when using this technique, Y'Shari can instantly kill all the creatures within a certain radius of a point he designates by absorbing their blood, causing them to bleed out profusely.
 * Maximum Power Bloodbath Violent Tide (最大功率血吸狂潮): Using Bloodbath Tide with maximum power, Y'Shari can instantly kill and absorb the blood of all the creatures within a five hundred meter radius of himself. Additionally, he can imprison their souls.
 * Blood Manipulation: Y'Shari has demonstrated the ability to manipulate his own blood, and other peoples' blood upon seeing it. He is able to fire his blood as tiny pellets from his wrist and onto other people. When done so, a small black dot is usually left at the point of impact on the recipient's skin. When manipulating another person's blood, Y'Shari prefers to use it to bind them by tethering their blood around their body.
 * Primordial Blood (始祖之血): Y'Shari can convert a large quantity of his own blood into a special blood known as Primordial Blood, which resembles normal blood but black in color. He can create three drops of Primordial Blood at full blood capacity. This special blood has a multitude functions, usually demonstrated by splashing a drop of it onto a person's skin.
 * Mind Control: By splashing a drop of Primordial Blood onto the forehead of another person, Y'Shari is able to subject that person under his control. The controlled person has unwavering loyalty to Y'Shari, described as if their allegiance was "engraved in their genes". The target still possesses some of their memories and can form coherent thoughts, but will obey his orders without question. If they question their loyalty to Y'Shari mentally, disobey his orders, or try to invoke their own memories, they will experience headaches. Sufficient willpower and important memories can bypass Y'Shari's control, as shown when Huang Xiaoyan vaguely remembered Ye Yan and freed him from his restraints despite being ordered by Y'Shari to kill him, even attacking her controller in the process.
 * Grave Enslave (深度奴役): Y'Shari can enhance the effects of his mind control on his controlled subject in the event that they are capable of disobeying his orders, even changing their personality. This also causes the subject's outermost clothing to turn black. However, sufficient self-awareness can counter the mind control and allow the subject to move freely.
 * Memory Awakening: Using a drop of Primordial Blood, Y'Shari was able to awaken portions of Xi Sha's latent memories from her previous incarnation.
 * Appearance Altering: Using a drop of Primordial Blood, Y'Shari was able to alter Xi Sha's appearance into that of her prime, which is her previous incarnation's appearance.
 * Copied Power Enhancement: By mixing a drop of Primordial Blood with another person's blood and then splashing it on his forehead, Y'Shari gains access to that person's most powerful techniques, even if they are unable to use them themselves. He demonstrated this ability by mixing his Primordial Blood with Ye Yan's blood, allowing him to attain the Night Conqueror form.
 * Power Replication: When manipulating another person's blood, Y'Shari also replicates that person's powers, albeit only most of their intermediate-level abilities and not their most powerful attacks. Additionally, when faced with an unexpected predicament, he can "realize" (明悟) the optimal technique among his available stolen techniques to use against his enemy by analyzing the situation.
 * Yellow Spring Demon Seal (黄泉封魔大印): After manipulating Yan Wen's blood, Y'Shari copied her Yellow Spring Demon Seal and used it to seal her into a stone statue.
 * Hundred Thousand Seal Formation (十万灵符阵): After manipulating Huang Xiaoyan's blood, Y'Shari copied her Hundred Thousand Seal Formation and used it against her, severely injuring and defeating her.
 * Darkening (黑化): After manipulating Ye Yan's blood, Y'Shari copied his Darkening ability, turning his scleras black and allowing him to generate and fire destructive green energy.
 * Night Purge (黑夜清君侧): After manipulating Ye Yan's blood, Y'Shari copied his Night Purge technique, which he used in an attempt to destroy Ye Yan in his Flag Demon form and his Flag Demons. Night Purge is an execution technique used by Nightwatchers in case their Flag Demons revolt against them. By releasing a green aura from themselves, the Nightwatcher indiscriminately kills all Flag Demons and any gaseous life form around them instantly. As such, this is a forbidden technique and is only used when no other options are left.
