Amber Lucifer

General Description
Amber Lucifer is a full-blood devil; the Princess of the Underworld; and the leader of Black Crown. After ignoring her problems down in the Underworld, she decided to move to other mortal world, where she met Zane Euphoria.

Appearance
As noted by Zane, Amber is very pretty, especially for a Princess. She has short, chin-length blonde hair and emerald-green eyes, both of which are recessive genes in the Lucifer bloodline. While in the Underworld, she dresses like a Princess would; while in the mortal world, she generally wears normal clothes, opting for brighter colors and refusing to wear the color black.

In Book 2, The Dragon-King Alliance, Amber loses her left hand in battle against Dragon Claw; afterwards, it's replaced by a metal hand that's made from the same material as Zane's armor.

Abilities

 * Destruction Magic: a type of magic that destroys anything it comes into contact with, Amber is a welder of this form of magic — which is considered one of the strongest — through her ring, which she inherited from her father. While Amber cannot destroy living beings like Zane can when he borrows her magic, she can destroy nearly all magical attacks.
 * Black Fire Magic: as opposed to normal Fire Magic, her flames are black in color; they burn hotter and are more destructive, but are also slower than normal flames when shot from a distance
 * Empress of Destruction: a transformation that shields Amber in an aura of Destruction Magic, which prevents her from taking any damage at all from ranged attacks

Personality
As seen in Book 1, Amber is pretty smart school-wise, but lacks a lot of knowledge to the social customs of the mortal world, which is noted by Zane when she is unable to understand the concept of privacy. However, during the events of Book 2, as she begins to become closer to Zane, she begins to learn a lot about the proper way to act, and begins to show more emotion as opposed to her usual stoic self.

Later in Book 2, though she still struggles to understand the concept of love, she realizes through the help of Kristina that she loves Zane, and wants to be by his side for as long as possible. In Book 3, after Zane, Umbra, and Spencer defeat Ivior, the Iron God-Slayer, Amber has a larger understanding of the concept, and even kisses Zane on the cheek after the battle.

By Book 4, Amber is much more expressive, as is noted by Zane as being energetic and full of emotion, which was a complete contrast to how she was in Book 1. Half-way through the book, she confess, to the best of her abilities, her feelings to Zane, which are reciprocated but delayed to the upcoming battle; at the end, the two finally share a kiss, and by Book 5 are dating.

Relationships

 * Melanie Bernard: the first friend that Amber makes in the mortal world, and the first person to join her guild, Black Crown, Melanie was the closest person that Amber had to a best-friend, up until her death at the hands of Jay Valentine in the war between the Underworld and the Alliance.
 * Divinos: though Divinos later joins Black Crown, it's noted by Zane that whenever Divinos spoke to Amber previously, there was a clear condescendence in his voice; however, this dissapearences after he allies himself with the guild.
 * Chloe Murphy: one of Amber's best friends and her previous advisor, the two were very close to each other until Chloe's death in her battle against Van, the White God-Slayer and the villain of Book 1.
 * Zane Jackson: During the first book, the two are only ever seen talking if Zane needs something explained in the magical world, or if he's in need of a little confidence booster; before splitting up in the war, however, Amber tells Zane that if he dies, she'll be the one personally torturing him in Hell. During the Dragon-King Alliance, Amber begins to realize, with the help of Kristina, that she's begun to develop romantic feelings for Zane, after the two begin to go on many quests and missions as a duo. Though she finds it hard to understand the concept of love and what she's feeling at all, Amber attempts to conceal how she feels towards Zane when in his presence. Due to her inability to understand love, Amber is also ironically oblivious — as noted by Lance — that Zane has begun to see her romantically as well, which leads to a numerous amounts of awkward moments between the two.  At the end of the second book, in the final few chapters, Amber asks Zane for a large favor: enter the upcoming tournament in the Underworld, which would decide who the Princess of the Underworld would marry. While declining at first due to realizing her has feelings for her and the awkwardness that marriage at that stage would bring, Zane eventually accepts the offer as he realizes that it isn't just about him, and that Amber shouldn't be forced to marry anyone if she didn't want to.   In the final round, Felix easily defeats Zane, but it's due to the cockiness of the former that triggers Zane into activating his Crimson-Gold Dragon-Slayer Mode, which is when Amber discovers than Zane is able to use Fire Devil-Slaying Magic. Using the short burst of power to take in the win, Zane is crowned the champion; however, in the final scene of the second book, Zane is seen asking Lucifer for a favor — allowing him to marry her traditionally and fairly through Amber's consent. During the third book, The Path to Tartarus, Amber accompanies Zane on his quest to confront Afeus, and it's only thanks to her that Zane is able to overcome the mental games and trauma that Afeus plays on him; throughout the book the two share moments, but don't progress too much until the end.  At the end of the third book, after Zane defeats Afeus using his Steaming-Gold Dragon-Slayer Mode, Amber leans up and kisses him on the cheek, thanking him for playing the role of hero again.   In Black Crown & The Ironworks of Conquest, the fourth book, the opening scene displays the two attempting to "hang-out" like normal mortals would, but their day is interrupted when Reaper Kurosami appears before them, warning them of an impending danger — Ivior Gurren, the Iron God-Slayer and the fourth survivor of Project G-S.   Later in the book, when they're preparing to invade the Underworld and take it back from Hylax, Amber confesses her feelings to Zane and tells him that she doesn't expect an answer yet. After the battle, Zane also confesses his feelings, and the two end up sharing a kiss.  Throughout Book 5, Black Crown & The Necromance of Black, the tension between the two is noted by Lance as being awkward, with the two already having confessed and kissed, but not yet dating or in a romantic relationship. In the events of the book, Zane's mental health begins to decline as he faces the Shinriyoku, with Amber at the end being the one who helps him recover.   In Book 6, Black Crown & The Phantom Shield, it is stated that two are officially dating.
 * Ruben Brown: as one of the first members of Black Crown, Amber and Ruben are respect each other as friends, and also come up with strategies for the group from time-to-time
 * Hailey Luna: At first, Amber was jealous of how close and how quickly Hailey was getting to Zane, even going so far as to calling her food and teasing her from time-to-time; however, over time, she came to accept her as another friend.
 * Jay Valentine: though he was the person who killed Melanie, Amber eventually accepts his apology after she realizes that he's changed, and invites him to join Black Crown — though that only happens when Zane finally agrees that he's changed.
 * Lagann / Kieron Bernard: Since Kieron was Melanie's long-lost brother, Amber feels a responsibility to make sure that Kieron is a good state mentally, and is seen giving him advice from time-to-time whenever she can. In Book 3, after Lagann's fight with Zane, Amber invites him to join Black Crown, which he accepts.
 * Mio Tsukomi: after Mio joins Black Crown through Zane's invitation, the two become good friends, noted by Lance as hitting it off almost immediately
 * Lance Frazer: the two respect each other as friends, and are seen fighting alongside one another in several battles
 * Umbra: while noted by Zane as being a complex relationship, Amber considers Umbra as a sort of older brother figure, with the ladder referring to her as "Princess".
