Tamaki Kotatsu

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

Appearance
Tamaki is a young girl of average height with long, straight dark hair and two ponytails that come out at the sides down to her shoulders. She wears a protective outer jacket, with an open torso, which reveals her entire stomach area, trousers and dark boots.

Personality
Tamaki has a very vulgar personality. She is loud and boastful, and is not shy of her appearance in the slightest. Tamaki is also quite clumsy, which results in her getting into intimate situations, for which she blames others. She also gets annoyed with people rather quickly and doesn't like it when her superiors are disrupted by low-ranked Fire Officers, like Shinra. On the battlefield, Tamaki is observant, as she managed to notice Shinra not having any sense of urgency.

Abilities
Tamaki along with her brigade are all elite Special Fire Brigade officers. Being a Third Generation, Tamaki has adapted to the Human Body Ignition Phenomenon and was granted the ability to ignite and manipulate flames from her body. While using Nekomata, she gains cat like traits which can be used for a range of things such as increasing her agility by running on all fours or to use her tails to capture an enemy, which have enough ferocity to launch an object flying into the sky.

Introduction arc
Tamaki participates in the Fire Officer Newcomer Tournament, where she meets Shinra and does not realise his initial infatuation with her, which leads to Tamaki getting rather annoyed with the boy staring straight at her with his devious grin. When Shinra approaches Burns, Tamaki attempts to stop him, but accidental gets groped in the process by him and other officers to her dissatisfaction. When the competitions begins, she notices Shinra igniting his feet to fly to the finish line, which makes her activate Nekomata to get there quicker. Inside, she finds herself in a compromising position with Arthur, after the building was attacked by a fellow participant. Searching for the "Flame Human" together, Tamaki is attacked by a stranger, but his attack is stopped by Arthur.

Thinking the stranger is the acting Flame Human for the competition, Arthur attacks him, but is unable to hit him with Excalibur, leading to Tamaki joining in and uses her tails to surround and capture the individual. Retaliating, the person attempts to detonate Powder around Tamaki, but finds herself saved by Shinra before it explodes and comments on how unexpectedly dangerous the tournament was. As the strangers leaves, the three officers become surrounded by powder, leading to them working together to escape the building and find themselves launched in the sky, as the building underneath is destroyed. Falling towards the ground, she is caught by her Battalion Commander and safely land. Burns thanks the boy for saving her, though she stubbornly says she could have saved herself. Burns then asks her for a briefing on what happened within the building.
