Appearance

Hei is a young and quite tall man of slender build with black hair and dark blue eyes. When in his Li Shengshun persona, he wears the casual attire of an exchange student, mainly white button-down shirts with rolled up sleeves, blue jeans, grey sneakers and a forest green hooded jacket. When operating as a Contractor, Hei dons a black bulletproof trench coat with a high collar and lime green interior, black tactical harness, matching pants, gloves and sweater, black combat boots and a white pierrot-inspired mask with red lips and purple thunderbolt over the right eyehole that fully conceals his face.

Backstory

Before he became a Contractor, Hei was a caring older brother who looked after his little sister, Bai as her guardian despite his young age. During a meteor shower, his sister became a Contractor with the ability to control and change matter on a molecular level, causing her to become the original BK-201. Soon after, Bai was recruited into the Syndicate. Although Hei hated killing, he became a mercenary in order to watch over and be with his sister. Due to his exceptional capabilites in martial arts, improvised weaponry, and speed, Hei became feared even amongst contractors, earning the title of "Black Reaper". However, as "Heaven's War" went on, Hei became appalled by his sister's actions and began having thoughts of killing her, but his love for Bai prevented him from doing so.

Equipment

Knife: His trademark weapon is a knife on a metal wire, which he uses as an offensive weapon, a grappling hook, or as a conduit through which to discharge his electricity. Wire: In addition to using it with his knife, Hei also uses his wire with a carabiner attached to the end, which allows the wire to anchor to any object that it wraps around. This is also used to wrap around enemies necks and allows Hei to deliver lethal shocks. Crossbow: To aid in infiltrating a building, Hei has made use of a collapsible crossbow to fire a rope large distances. He keeps the crossbow in a satchel.

Personality

As a member of the Syndicate, Hei regularly takes on false identities and personas for his missions and day to day life, such as Li Shengshun, a good-natured, timid Chinese exchange student who is always eager to help others, but otherwise generally keeps to himself. Hei is a calculating assassin. Unusually for a Contractor, Hei exhibits and sometimes acts upon emotions. Even though Hei is a tactician, when he decides on a certain aim, it is nearly impossible to get him to change his mind. He tends to take great, stubborn and often irrational measures to reach his objective. Hei also has a huge appetite, often surprising people with the amount he can eat. Despite having the power of a Contractor, Hei still has his human emotions. He deeply cares for his sister.

Skills

Peak Human Condition: Hei's contract powers are especially useful because of his amazing agility, speed, endurance, dexterity, and natural strength.

Expert Hand-to-Hand Combatant: Hei is obviously extremely skilled in martial arts and is an accomplished acrobat easily able to do back-flips and mid-air cartwheels with little effort in terms of physical strain. Hei's natural abilities are so impressive that even without his contractor powers Hei is easily able to take on other contractors.

Tactician: Not unlike many Contractors, Hei possesses a very pragmatic and resourceful intellect; demonstrating a knack for improvisation during the heat of combat. Since Hei's contractor ability can only kill once in direct contact with the intended target, Hei often relies on taking his opponents by surprise in order to gain the advantage. His tactical unpredictability and resourcefulness coupled with his almost bullet-time speed makes him a daring foe.

Contractor Powers

Molecular/Electricity Manipulation: Hei possesses the ability to generate and discharge electricity through conductive media (i.e. he cannot discharge it through air or concrete) at sufficiently high amounts to kill grown men or short out a building's electrical systems. He has shown masterful efficiency with this power, being able to channel electrical currents through a wire and into his knife. This power is far more than simply releasing electric shocks, as he can alter matter on the quantum level, transform integral particles on the quantum level, and even generate special particle luminance; meaning he is able to change molecules similar to how humans are changed into contractors making it one of, if not, the strongest and most coveted powers known as it is the only ability capable of altering gate particles at will. This ability is not actually his as he is really only human, but was granted to him when his sister fused herself to him. Note that Hei doenn't have an Obeisance like any other contractors because he is still human, just fused with his sister.

Important Information

The Syndicate is an organization which operates behind the scenes at many levels, right up to leadership roles in the police, government and PANDORA. They are the primary antagonist of the series, despite that the main protagonists, Hei, Yin, Huang and Mao, have all worked for the Syndicate.

Pandora (Physicalquantity Alternation Natural Deconstruction Organized Research Agency) is a research facility in Tokyo dedicated to studying the phenomena of Hell's Gate. It is independently administered under the direct control of the United Nations

The Hell's Gate is a mysterious and chaotic area of space that appeared in Tokyo ten years before the start of the series, giving rise to Contractors and Dolls, at the same time as the moon vanished and the real sky was replaced with a false one.

Contractors are individuals who have gained superhuman powers due to the appearance of the Hell's Gate and Heaven's Gate.
