Three

Three was a member of Sun, as well as a swordsman and a Nightwatcher, though it is unknown which main branch family he belonged to.

Background
Three was born in one of the main branch families of the Nightwatchers, as he is able to wield multiple Demon Flags, a feat only accomplishable by main branch Nightwatchers. At some point in his life, he joined the anti-Department of Night organization, Sun. Later on, he met Ye Lanlan and attempted to exploit her low self-esteem by provoking her to kill Ye Yan, but failed and was beaten up by her instead. A month before the current timeline, Ye Lanlan came to him and asked to join Sun, and was subsequently recruited.

Personality
Three was manipulative and successfully convinced Ye Lanlan and Gu Xiaohua to join Sun, though both of them initially rejected him and beat him up.

Three was extremely loyal to Sun. However, he was ultimately killed by the organization after being framed by Ye Lanlan for attempting to murder her, a fellow Sun member, which is a taboo amongst the organization.

Appearance
Three has long black hair and small eyes. He has a slightly darker skin tone than most characters, and is always seen wearing a green trench coat and a black shirt under it, as well as black pants and black shoes. He wore a watch on his left wrist, and a necklace which contained explosives that Ye Lanlan secretly stored in. After being injured by Left-hand Man and Right-hand Man, Three wore a cast over his right arm and had bandages on his face.

Abilities and Powers
Three was a main branch Nightwatcher and possessed three Demon Flags. He also possessed a sword and seems to be somewhat proficient with it. However, he seems overall weak, as he was easily beaten by multiple people through pure physical strength.

Weapons

 * ThreeDemonFlags.pngDemon Flags (煌妖幡): A Nightwatcher exclusive weapon, it is used to capture monsters, atomize their bodies into green smoke along with their soul and enslave them as Flag Demons for eternity. Flag Demons are capable of making themselves invisible and intangible by turning themselves into green smoke, they are also able to solidify themselves to deal a surprise attack. Nightwatchers are able to telepathically communicate with their Flag Demons within a few hundred meters. According to Wang Shengli, a Nightwatcher that can control more than four flags is able to store three Flag Demons at most in one flag.


 * ThreeSword.pngSword: Three possessed a sword and attempted to use it to kill Left-hand Man and Right-hand Man. He self-proclaims to be a swordsman so it can be assumed he is at least proficient in using it.
