Tamaki Kotatsu is a 17-year-old female Fire Soldier, currently serving with Special Fire Force Company 8 after a prior assignment in Company 1. Born February 22nd, she stands 156 cm tall and weighs between 41-47 kg. Her appearance features long, straight dark hair typically styled in twintails, striking golden eyes with white pupils, and a slender yet curvy figure. On missions, she wears dark undergarments, a protective jacket fastened with cross-shaped buttons, a neck protector, dark boots, and gloves, often accented with blue lines and designed with minimal coverage that exposes her midsection. Off-duty attire includes modest dresses with long sleeves or Company 8's orange jumpsuit. Activating her pyrokinetic abilities manifests cat ears, two forked tails composed of pink flames, and claws. Her background includes experiencing school bullying due to clumsiness, leading to social isolation. Inspired by Rekka Hoshimiya's warmth and encouragement after a friend became a nun, she pursued sister training and joined Company 1. This followed her accidental manifestation of pyrokinetic abilities at school, sprouting fire tails after a fall. Her inherent "Lucky Lecher Lure" trait—extreme clumsiness causing frequent unintended compromising situations—contributed to low self-esteem and feelings of being a burden. Despite this, she demonstrates kindness, loyalty, and protectiveness towards teammates and children, alongside classic tsundere traits and implied romantic feelings for Shinra Kusakabe. Her strong sense of justice compelled her to defy Rekka upon discovering his human experimentation, enduring a violent beating to call for help. As a Third Generation pyrokinetic, Tamaki wields the Ignition Ability "Nekomata," granting immunity to burns and control over pink flames. This power enhances her agility, enabling movement on all fours, rooftop traversal, and high-speed dashes. She manipulates her fiery tails to propel herself, generate explosive blasts capable of breaking walls, restrain targets within fire circles, or create distress signals. Training with Company 7's Benimaru Shinmon unlocked latent potential, improving her flexibility and enabling larger flame constructs like humanoid cat forms and transparent fangs. Her combat skills encompass crisis management, tactical analysis, and using clothing as fuel for firepower. She possesses enhanced durability, surviving assaults from powerful opponents like Rekka and Assault, and heat resistance against high-temperature attacks. Her development spans key arcs. During the Rookie Fire Soldier Games, she allied with Shinra Kusakabe and Arthur Boyle against Joker. Witnessing Rekka's betrayal in the Company 1 arc led her to signal for help and assist in his defeat. Transferred to Company 8 as disciplinary action, she supported investigations into the Preacher and White Hoods. In the Netherworld incursion, she protected Iris and defeated Assault by using her Lucky Lecher Lure defensively. She served as the team's nun during the Chinese Peninsula expedition. Confronting her insecurities solidified her resolve; she trained rigorously to overcome self-doubt, vowing to become a reliable combatant. By the series' conclusion, she balanced combat duties with religious services as a nun, wearing a combined habit and Fire Force uniform. Controversies surround her character, particularly the narrative emphasis on her Lucky Lecher Lure. Critics cite repetitive fanservice scenes as undermining serious moments and character agency, while supporters highlight occasional tactical utility (e.g., incapacitating Assault) and comedic intent. Debates also focus on perceived underutilization in combat compared to peers, though later arcs address this through dedicated training and power unlocks.
