Tamaki Kotatsu

is a Third Generation Second Class Fire Officer of the 1st Special Fire Brigade.

Appearance
Tamaki is a young girl with long, straight dark hair tied into twintails. On missions, her outfit consists of dark undergarments, a protective outer jacket, a neck protector, dark boots and protective gloves. Parts of her outfit are coated with blue lines. Tamaki's torso is open, revealing her entire stomach area. The sleeves of her jacket appear to be too long for the arms and the buttons are in the shape of cross-like symbols. Her outfits contain patches with "1" on it, to signify Tamaki's affiliation to the 1st Special Fire Brigade. When residing at the 1st Special Fire Fighting Cathedral, Tamaki wears a more modest outfit, which consists of a light dress, a dark-coloured garment with long sleeves over it, leggings, dark shoes and a headband. Tamaki's collar is tied up with a string in a ribbon-like fashion that has a cross-like button on it. While under the effects of her Ignition Ability, Tamaki gains noticeable cat-like traits, which include two forked-tails, cat ears and claws.

Personality
Tamaki has a vulgar personality. She can be loud, boastful and is not shy of her appearance in the slightest. She is known to be very clumsy and has "Lucky Lewd Syndrome", which results in her getting into intimate situations, for which she blames others. Tamaki is easily annoyed by other people and shows dissatisfaction when her superiors are confronted by lower-rank Fire Officers. She is very proud of the 1st Special Fire Brigade. According to Leonardo, Tamaki often gets herself in uncomfortable situations. Tamaki is courageous and has a strong sense of justice, as she was willing to disobey Rekka after seeing how he treated innocent people, going as far as slap him, even though it resulted in her being beaten up violently. As she highly admired Rekka as a person as well as a superior, Tamaki displayed deep emotions when she found out his evil intentions.

Abilities
Tamaki is considered to be an elite within the Special Fire Brigades, due to her affiliation to the 1st Special Fire Brigade. Being a Third Generation, she has adapted to the Human Body Ignition Phenomenon and was granted the ability to gird herself in flames, which grant her various cat-like traits, including cat ears, two forked tails and nails on her fingertips, an ability she dubbed "Nekomata". With her Ignition Ability active, Tamaki's agility and mobility is substantially increased, allowing her to run on all fours. She can use her forked-tails to generate a blast of fire, which is strong enough to inflict damage to building walls, or restrain her targets. On the battlefield, Tamaki is quite observant of her surroundings.

Introduction arc
Tamaki participates in the Fire Officer Newcomer Tournament, where she meets Shinra and gets irritated with him staring straight at her with his devious grin. Tamaki attempts to stop Shinra from approaching Leonardo, but gets groped in the process, much to her dissatisfaction. When the simulation exam begins, she notices how further Shinra has advanced, which pushes her to use her own Ignition Ability in hopes of recovering her position. Inside, Tamaki teams up with Arthur to fight Joker, despite Shinra's warnings, thinking it to be part of the exam. When the stranger uses a substance to detonate the building, Tamaki decides to ally herself with the two Fire Officers in order to survive the jeopardy. When she starts falling from the sky, Leonardo catches her, after which she stubbornly claims that she could've survived on her own accord.

VS. 1st Special Fire Brigade arc
When trainees from the 2nd, 5th and 8th Brigades arrive at the headquarters of the 1st Special Fire Brigade, Tamaki recognises Shinra in the crowd and spectates the event. After training, when a Flame Human was spotted in the Shinjuku District, Tamaki informs the newcomers of the emergency and directs them to their respective Company Commanders for the duration of the mission. Afterwards, she leads a few people to an abandoned building, where Rekka claims to know of a prayer that can protect people from succumbing to the phenomenon.

Tamaki, asked to be dismissed so Rekka can focus on the prayer, insists she stays because she wants to witness it with her eyes. Tamaki is then hugged by Rekka, and who starts thanking her loudly. The hug soon turns into painful suffocating, and Tamaki collapses from a short of breathe. As she lays on the ground, she witnesses Rekka turn a mother into a Flame Human and kill her brutally, and realises he isn't the man she thought he was. After recollecting herself, Tamaki slaps Rekka for conducting experiments with people's lives, but is quickly punched and told that she will not intervene with his passion for violence.

Tamaki then lets out a loud cry for help, and uses her ability as a distress signal. When Rekka notices her disobeying him, he starts repeatedly kicking her, but all she can think of is how much she admired him. Suddenly, Shinra bursts in and stomps Rekka onto the ground, saving Tamaki from harm. Shinra asks if she's okay, but she's too overwhelmed to say anything. As Shinra and Rekka engage in battle, Tamaki is surprised by Shinra's ability to fight on par with the priest. As Rekka throws his fiery punches repeatedly, they land on Tamaki's clothes and they burn away, leaving her in just a bra and knickers. After Shinra repeatedly lands on her seductively from falling down, Tamaki grips onto his back, unable to look him in the face, and begs him to put a stop to Rekka once and for all. As he dashes forward to attack him, she encourages him.

Trivia

 * A "Kotatsu" is a table frame, covered by a heavy blanket, upon which a table top sits, and is exclusive to the Japanese culture. Domestic cats are often portrayed sleeping underneath them for warmth, as Japanese homes don't generally have floor heating vents.
