Ayano Kannagi

Ayano Kannagi is the main female protagonist of the series. She is the future head of the Kannagi family, the inheritor of Enraiha and the daughter of the current head Jūgo Kannagi. She is also the second cousin of Kazuma Yagami and Ren Kannagi, as well as the love interest of the former.

Personality
Ayano takes her role as the next head of the Kannagi family very seriously. She's brash, short-tempered, impetuous and easily as arrogant as her cousin. She rarely thinks things through, preferring to charge in blindly to situations and believing that any problem can be solved with brute force. Her pride for her family and heritage is often the fuel for her recklessness, as she believes her family name and force alone would allow her to beat anyone. Whenever a problem arises for the family, Ayano is usually unable to see that it was the very policies of the Kannagi family that caused the problem in the first place, believing that there is nothing wrong with the way the Kannagis do things. She can also be very stubborn, sometimes refusing to admit when she's wrong even if all the evidence points against her.

Despite claiming to hate Kazuma, Ayano develops a crush on him, but gets angry when he flirts and makes a move on her and is prone to throwing fits of rage when he gets close to another woman, making her a tsundere. She later comes to realize that she is actually in love with him. Kazuma is also the only person she sees as stronger in power and presence than even her own father.

Ayano also has something of a sweet tooth, spending a lot of time at cake shops after school and gorging herself on sweets, especially if she's in a bad mood.

Despite her undisciplined attitude and short temper, Ayano is a kind person who cares a great deal for those close to her. However, much like Kazuma, she can also be brutally honest at times, such as when she bluntly told Ren he abandoned Ayumi and that sitting around feeling sorry for himself wouldn't solve anything. Ayano also takes any insult against her family very seriously, which is especially shown in the anime with her fight against Catherine McDonald, saying she would sooner die than hand over the title of her clan to 'some random family'.

Later in the series, it is shown that, however arrogant she may act on the surface, the massive gap between her power and Kazuma's has left her with serious self-esteem and confidence issues, causing her to doubt herself frequently and worry she might mess things up. Her insecurities are especially shown when, after Kazuma declares that he'll protect her, she takes it completely the wrong way and asks if he sees her as a helpless little girl who can't take care of herself.

History
Four years before the events of the show, Ayano defeated Kazuma in the Right of inheritance Ceremony. She was crowned the heir for the Kannagis and recieved Enraiha.

Abilities
Ayano is an En-Jutsu user and is very skilled at it. Her fire is often fueled by anger, especially anger towards Kazuma. Ayano's flame is the Crimson Flame, though she cannot control it consciously. She temporarily wielded the Azure Flames when Kazuma's Contractor magic combined with hers during their fight against Michael.

She is also a skilled swordsman because she wields Enraiha.

Relationships
Kazuma Yagami- Initially, Ayano was very hostile towards Kazuma, mainly because she believed him to be the Kannagi murderer. Afterwards, she began to see him as a jerk due to him charging Jugo for saving Ren, greatly annoyed that he would demand money for saving his own kid brother. As the series progresses, she became less hostile but still is rather cold towards him, though he is cold to her in return. However, she soon fell in love with him but often denies it. She easily becomes jealous when Kazuma is often with another women, but denies caring about it. Because of this, Ayano is considered a textbook example of a Tsundere because of her outward hostility and inward softness towards Kazuma. Eventually, Ayano admits that she in fact always looked up to him, wishing that one day she could be as strong as he is.

Ren Kannagi- Ayano cares a great deal for her younger cousin, who look up to her in return, affectionately calling her 'Nee-sama'. She often teases him, much to his dismay. However, sometimes Ayano feels jealous of him when Ren demonstrates techniques that she can't use or had no prior knowledge of. Much like Jugo, Ren is a big supporter of the growing feelings between Ayano and Kazuma and hopes the two will one day be honest with their feelings.

Jūgo Kannagi- Ayano greatly respects and fears her father. She often willingly takes missions from him and always wants to make her father proud. She also wants to prove to her father that she is capable of leading the family, much to the dismay of Jūgo as the ways she attempts to do so are often incredibly reckless..

Yukari Shinomiya and Nanase Kudō- While it's not known exactly how long the three girls have known each other, it's clear that they are very close. Yukari and Nanase are the only people at Ayano's school who know about her powers; in the anime, they know from the beginning but in the novels, they don't know until the second volume. Much like Jugo and Ren, Yukari and Nanase are huge supporters of Ayano's feelings for Kazuma and often tease her about them, which frustrates her to no end. Despite this, she cares for both of them a great deal, once saying she couldn't have better friends due to the fact that they aren't afraid of her in spite of her very lethal magic abilities.

Catherine McDonald- Ayano saw Catherine as her direct rival at first. After Catherine enlisted Kazuma to train her after she lost their first duel, Ayano saw her also as a romantic rival. They dropped hostilities as direct rivals but continued to be romantic rivals throughout the remainder of the series. She is also jealous and envious of Catherine Mcdonald's beauty and her breasts.
