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. 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
Being a Third Generation, Tamaki has adapted to the phenomenon and was granted the ability to ignite flames from her body. She is able to use the flames to substantially increase her agility, giving her cat-like traits in the process.

Introduction arc
Tamaki participates in the Fire Officer Newcomer Tournament, where she meets Shinra and does not realize 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 finds the man from the 1st Special Fire Brigade, the one who helped him in the past, he attempts to approach him, but Tamaki gets in his way and orders Shinra not to bother her superior. Her attempt causes Shinra to grope her by accident. She attempts to slap him, but is unsuccessful and, due to her clumsiness, waddles towards Arthur and embraces him, then immediately pushes him away, claiming him to be a pervert. As Tamaki bumps into Shinra yet again, the boy accidentally gropes her once more. When the competition starts, Tamaki wonders why Shinra is not moving from his initial position. She then sees the boy using his abilities to jump onto the building, which leads to her using her own abilities to increase her own mobility and agility substantially in order to catch up to him and recover her position. Later, when the young man from the 2nd Special Fire Brigade bombards the building with his abilities, Tamaki, who was inside at the time, falls onto Arthur, causing her to lash out at him for supposedly being a pervert, but the boy just tells her that he is neither a cushion nor a sandbag.
