Cain

Cain: "Ah. You're finally awake."

Conley Mitchell: "Finally awake? What do you... What do you mean?"

--Cain's first appearence

Cain is a demon who, like the Mitchell Family, has been hunting the storm demon. Coming from Hell, Cain revealed to Conley that he is wanted by almost every demon and demonic leader of Hell. He has also revealed that he was once considered a demonic leader, much like the storm demon.

Early Life
While almost nothing is known about his life when he was alive, it is known that he must not have been a good person to have gone to Hell upon his death.

While in Hell, he encountered the storm demon, a demonic leader with his own Cult. Like the storm demon, Cain was also a demonic leader with his own Cult. However once he began hunting the storm demon, he left his Cult in Hell to find Bane himself, resulting in him being hunted by almost all of demon-kind and possibly losing his status as a demonic leader.

Life in Hell
" "

--Cain about his life in Hell.

As a demon in Hell, Cain eventualy rose to be known as a demonic leader and had his own Cult along with a very small portion of Hell being considered his. However he preferred not getting involved in the demonic warfare and thus he kept his Cult in his part of Hell.

However, the storm demon preferred the fighting, commonly attacking other demonic leaders and their Cults. At some point, he attacked Cain's Cult and completely wiped them out, taking Cain's small portion of Hell and leaving Cain the only survivor.

Once he discovered that the storm demon had left Hell to try and free Lucifer from Lucifer's Cage, he found a way to leave Hell to stop the storm demon, mostly out of hate for killing off his Cult, going as far as to consider his previous demon followers as friends.

Appearence
"Turning to his left where he heard the man's voice, he saw that he looked rather young, maybe just a little bit older than Conley was, and had jet black hair. He was also fairly muscular but not as much as he was. He was sitting at a small clear table and was reading a book. Conley wondered how he could be reading while he was wearing sunglasses."

--Conley on seeing Cain for the first time.

Cain has black hair and fair coloured skin as well as possessing pure black eyes with no whites in them, a common trait for demons. He has a fairly muscular built though not as much as Conley and is about the same height as Conley, being one or two inches taller.

To hide his black eyes from normal view, he commonly wears sunglasses to avoid drawing suspicion or avoids making eye contact. He typically wears dark coloured clothing that also sometimes has the appearence of being burnt, showing that he is a demon of Hell.

He also has fanged teeth, much like a vampire.

Personality
Cain: "Well it was a choice I made. Just like how I am making the choice not to rip you apart right about now."

Conley Mitchell: "You're all heart, aren't you?"

Cain: "I prefer to think of it as flirting."

--Cain's arrogant persona. Like most demons, Cain as an egotistical persona about him, feeling that he is better than everything and everyone. Though a demon, he saved Conley Mitchell from death when the T.E.N.S. Prime Building collapsed from the storm demon as he felt that Conley was the best person who stood a chance against the storm demon, showing his strategic intellect.

He is also shown to bond quickly with people, quickly becoming good friends with Conley Mitchell and giving him a demonic knife that can be used to call Cain to him, even giving one to Conley to give to Daniel Mitchell should the deaf boy ever be in trouble.

Though very arrogent and egotistical, he also knows the limits of his own demonic powers, knowing that while he might be able to go toe to toe with the storm demon, he would be unable to kill him, hence why he saved Conley Mitchell.

The Boxes of Lucifer
While Conley fought his way through the T.E.N.S. Prime Building in Tokyo, Cain followed him in pursuit of the storm demon. When the storm demon dropped a massive red lightning bolt onto the building and caused it to collapse, also greatly injurying Conley, Cain saved him and took him back to his small house in the forests of Tokyo.

Conley Mitchell: "Wait, a demon can be wanted by other demons? I thought you were a demonic leader or whatever you are?"

Cain: "I am. But my entire Cult is still in Hell. I came up here solo."

Conley Mitchell: "How suicidal."

--Conley Mitchell discussing Cain being wanted by other demons.

Once Conley recovered after a month, he took him back to Tokyo where he gave him a demonic knife to use to call him should he ever be needed. He also gave him one to give to Daniel Mitchell for his birthday, warning him not to actually touch the blade itself until Daniel does first, otherwise it will recognize Conley's call first instead of Daniel's.

He was then called by Conley during the Battle of Lakeview Road, being stopped by Kenton Alexandria, Marcus Nolan, and Ayumi Hiyashibara. Once Conley explained that he called them, the group, minus Ayumi, left the E.N. Security building to recover the boxes of Lucifer.

He later confronted the storm demon alongside Conley, Kenny, Marcus, Aaric Mitchell, Mason Mitchell, Daniel Mitchell, Caleb Mitchell, Alex, and Kristen, who the latter of which is a witch. There, he witnessed Mason killing some fifty or so demons single-handedly and witnessed Daniel killing the storm demon.

Three weeks after the battle, Cain is mentioned to still be on good terms with the Mitchell Family as Conley still gave Daniel the demonic knife for his birthday.

The Ephemeral Line
While not officially confirmed, it is possible Cain will return in The Ephemeral Line.

Demonic Abilities
Wisping: Wisping is a demonic ability possessed by Cain that allows him to teleport to various places. Cain's skill with this demonic ability is great enough that he can wisp to a place in midair to catch a falling Conley Mitchell and then wisp immediately after that.

Intellegence: Being a demon and almost becoming a demonic leader, Cain has a vast knowledge of demons and Hell as well as other demonic entities and demonic abilities.

Demonic Knives: Cain also has the ability to fashion demonic knives that he can then give to various people who can use them to call him to them simply by holding the blade and thinking of his name. He also makes them recognize the first person who touches them, besides him, so that only that specific person can use them.
