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
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 flames from her body. She is able to capture a target by surrounding them with flames and is also capable of increasing her agility by giving herself cat-like traits while running on all fours.

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 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 actions 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 ability, 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.

Tamaki and Arthur follow the path together, and notice a nearby explosion just around a corner. Arthur tells Tamaki to go first since she is a lady, to which she does, though questioning his acts. Out of nowherere, Joker throws one of his fire-cards at her unprepared. Arthur intervenes and slices it with his Excalibur, and getting excited about the fact that he found the fake Flame Human, much to Tamaki's displeasure as he went ahead of her even though he said she should go first. Shinra attempts to tell the duo that he is actually a bad guy and for them to get the Commanders for help, but they don't listen. During Arthur's and Joker's spar, Tamaki interrupts in an attempt to trap Joker who she thought of as the fake Flame Human, posed for the tournament, but really was an intruder. She leaves Joker with no where to run by using her tails in Nekomata form to trap him, but he sneakily releases some of his Exploding Powder. Unexpectedly, an explosion goes off in Tamaki's direction, but luckily Shinra made it in time to save her. Tamaki mentions that the attack was a little too hardcore for a tournament like this, but Shinra tells them again that he isn't part of the tournament. As Joker releases the rest of his Exploding Powder, Shinra yells at the pair to escape immediately. Joker escapes saying his last words to Shinra, and the top floor of the building explodes with the trio still inside.
