Tamaki Kotatsu

is a Third Generation Second Class Fire Soldier formerly in Special Fire Force Company 1. Due to her service for Rekka Hoshimiya, she is being disciplined under Special Fire Force Company 8's watch.

Abilities
As a Third Generation pyrokinetic Tamaki is immune to most burns and can use her Ignition Ability to create herself in pink flames. Her powers grant her various cat-like traits when activated, including: cat ears, two forked tails and nails on her fingertips. This is an ability she dubbed "Nekomata". With her Ignition Ability active, Tamaki's agility and mobility are substantially increased, allowing her to run on all fours and across rooftops. She can use her forked-tails to propel herself forwards or upwards or generate a blast of fire, which is strong enough to break through building walls, or repel Infernals. She can also restrain her targets in a circle of fire by lengthening these tails, or using them as a distress signal by the same process. With additional training, Tamaki's abilities evolve to allow her to coat her entire body in flames which takes the form of a humanoid cat. She is also able to generate her larger, almost transparent flames in the shapes of fangs and other features. In this state, her flexibility improves dramatically and she is able to destroy large fire constructs created by powerful opponents.

Background
While attending school, Tamaki's clumsiness lead her to being ostracized by other girls at school, including verbal bullying and forcing her to sit out off the way. After her friend became a sister she assured Tamaki that she could pass the test to take the occupation as well, during which she fell over and sprouted fire tails. When her school peers found out she had become a Third Generation, they questioned if she'll become a fire soldier and join Company 1. Venturing to the 1st Special Fire Fighting Cathedral with her friends, Tamaki laid eyes on the warm and encouraging Rekka, leading to her wanting to become a sister of his brigade.

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 Human Body Ignition 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.

As she lays on the ground, she witnesses Rekka turn a mother into an Infernal and kill her brutally, and realizes he isn't the man she thought he was.

Tamaki then lets out a loud cry for help, and uses her Nekomata 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.

She soon finds herself saved when Karim intervenes and immobilizes him, before looking on as a light attacks Rekka, subsequently killing him in the process, much to Tamaki's shock.

As everybody is endangered by an unknown figure shooting flaming arrows into the building, Shinra creates a smokescreen to blind them, and Tamaki bites back by using her ability to extend her tails toward the snipers, which Karim freezes, scaring them off in the process.
