Hibana

is a Third Generation and the Battalion Commander of the 5th Special Fire Brigade.

Appearance
Hibana is a tall woman with tanned skin, long pale-blonde hair, thin eyebrows and aqua blue eyes with pink, flower-shaped pupils. Her brigade outfit consists of a personalised protective outer fur-tim jacket with a hood, no zipper, blue lines, which are a custom on a Fire Brigade's jacket, and a patch with the number "5" on it. Underneath the jacket, Hibana dons a v-shaped, sleeveless white pencil dress, which partially reveals her large bust. She also wears a belt with a gold buckle, with a whip and a holster attacked to it, black high heels, a golden necklace and light-coloured underwear. Hibana's dress has a split on the side from the belt down, providing full-front view of one of her legs. In her youth, Hibana wore a habit, which consisted of a tunic, covered by a scapular, and a veil, black shoes and a necklace with a cross-like insignia. She also carries a iron fan around her when on the battlefield.

Personality
Hibana takes her role as the Battalion Commander seriously and doesn't hesitate to remind lower-ranked members of their place. She is deceiving and has quite a twisted personality, as she seems to enjoy conducting experiments on Flame Humans, during which, even her own followers appear to be frightened of her. Hibana is ambitious - she wishes to gather as much data on Flame Humans as she can and unravel their secrets. She also has a goddess-like complex, which she expresses towards males, manipulating people using her charm and beauty and making them do her bidding, being dominant of them and thinking of them as insignificant; going as far as using her own comrades as stepping-stones from her throne. Hibana considers herself to be a demon within the world that she lives.

Abilities
Princess Hibana is a Third Generation, who was given the ability to generate flames through her iron fan. Due to her unique choice of weaponry, it is implied that she has some sort of skill in tessenjutsu. By gazing at her opponents, Hibana is able to control the heat of other people which she uses to put them under a heat trance that makes the target fall to their knees and prevent them from moving.

Background
Princess Hibana attended The Holy Sol Temple in her youth, with Iris as her colleague. Due to the honourific Iris uses when addressing Hibana, it is implied that the two share a close relationship. She previously worked for Haijima Heavy Industries as an employee, quickly earning a name for herself. Hibana eventually joined the 5th Special Fire Brigade, where she illegally experimented on Flame Humans and sold the data of her research, resulting in her becoming the brigade's Battalion Commander.

Introduction arc
Hibana spectates the Fire Officer Newcomer Tournament, where she supports her peers in the exam, until it is halted after an incident inside the building. Some time later, she interrupts the clash between Shinra Kusakabe and Setsuo Miyamoto in an attempt to stop the Fire Officer from dealing the finishing blow to the Flame Human.

VS. 5th Special Fire Brigade arc
Princess Hibana orders her subordinates to take the Flame Human away as she gazes at Shinra, causing him to fall to his knees. She then orders the 3 Angels of the 5th to hold the Fire Officer down while she lectures him on how to be respectful towards superiors. Hibana orders Shinra to lick her shoe and refuses to listen when Shinra attempts to explain his actions. When the Fire Officer spots her underwear by accident, Hibana becomes startled and walks away. She later explains the 8th Special Fire Brigade that she wishes to research the Flame Human and deceitfully claims that she is willing to share the information amongst the Special Fire Brigades. A stand-off between the brigades is then catalyzed, but the two depart without any signs of struggle.

After returning to the headquarters, Hibana begins viciously experimenting on Setsuo, tempting the man to reveal the secrets his body holds. When Iris arrives at the complex in order to speak with her, Hibana rips off the sister's habit and claims to be a demon living in this world. She then suggests using Iris as a bait to lure out the 8th Special Fire Brigade, after which Hibana overhears a loud noise outside the headquarters. As she recollects her past with the sister of the 8th Special Fire Brigade, Hibana is interrupted by Shinra. The Battalion Commander attempts to use her gaze to succumb the Fire Officer, but fails, as Shinra stands up through sheer willpower. Princess Hibana then takes out her fan and uses her Ignition Ability, prepared to fight the Devil.
