Jōnetsu Nagabi

Background
As the oldest of the foursome (herself, her brother, and her two cousins) she is a powerful ninja, something that is only confirmed when you fight her. From the age of two she was trained by her clan in the art of the fire release. This meant working day and night, often without sleep and food, to perfect the skills that had made her clan famous. Only after she had mastered the in and outs of the fire release was she allowed to take the challenge that would see if she had inherited the clan's Zeal release kekkei genkai. Fortunately for her, she had, so she was trained by her fellow clan members in the art of the Zeal release. As part of the training, she was taught basic skills in the taijutsu, something that would help her excel when she was sent to the Academy at the age of 6. Since many of the other Academy genin considered her to be too young for the Academy, they picked on her, to only find themselves, whipped and burned into submission. Thus she earned the name The Flame. The rest of her time at the Academy went by in a blur, and she found herself graduating to the genin level. Happy to be rid of those pesky people, she went on as many E and D missions that she could, so she could distinguish herself from the rest of her graduating class. It worked, as a year later she became a chunin, giving her the ability to go on D and C missions on her own. However, in true Yakeru fashion, she went on a A rank mission on by herself, scaring the other shinobi and even the hokage, who assumed that she had been captured, only for her to show up a few days later unscathed. This led to a heavy punishment heaped upon her by both the village and the Yakeru (though they were both secretly proud) and the delay of her jonin rank. She finally reached this at the age of 11. Her skill with her Zeal Release and taijutsu was such that she was called up by the ANBU at the age of 14, to take part in their capture and missing-nin missions.
