Tamaki Kotatsu

is a Third Generation Fire Officer at the 1st Special Fire Brigade.

Appearance
Tamaki is a young girl with long, straight dark hair and two ponytails that come out at the sides down to her shoulders. Her outfit consists of dark-coloured 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 her arms and the buttons are in the shape of cross-like symbols. Her outfits contain patches with "1" on them, to signify her affiliation to the 1st Special Fire Brigade. 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 is loud, boastful and is not shy of her appearance in the slightest. She is also quite clumsy and has a "Lucky Lewd Syndrome", which results in her getting into intimate situations, for which she blames others. Tamaki is easily annoyed by other people and does not like it when her superiors are disrupted by low-ranked Fire Officers, like Shinra. According to Leonardo Burns, she often gets herself in uncomfortable situations. Tamaki has a tendency to sometimes end her sentences with cat puns.

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 an unknown substance to detonate the building, Tamaki decides to work together with the two Fire Officers in order to save themselves from jeopardy. Falling from the sky, the girl is caught and delivered to safety by Leonardo, after which she stubbornly claims that she could have saved herself.

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.
