Tamaki Kotatsu, a Third Generation pyrokinetic, originally served with Special Fire Force Company 1 before her disciplinary transfer to Company 8 after unintentionally aiding Rekka Hoshimiya’s unethical experiments. Born February 22, she stands 156 cm tall with a curvy frame, weighing 41–47 kg. Her striking features include long dark hair styled in twintails, golden eyes with white pupils, and mission attire combining form-fitting protective gear—gloves, boots, and a neck guard—with an exposed midsection. Activating her Ignition Ability summons feline traits: flame-wrought ears, claws, and dual forked tails, embodying her "Nekomata" power. Hailing from a family suspected of Holy Sol Temple connections, Tamaki endured ostracization in school due to clumsiness and unpredictable pyrokinetic surges. Peers tormented her over the "Lucky Lecher Lure," an involuntary trait triggering frequent wardrobe malfunctions or compromising scenarios. Despite this, she entered sister training and joined Company 1, inspired by Rekka’s facade of compassion. Her loyalty fractured upon uncovering his creation of Infernals, spurring her defiance and alliance with Company 8. Tamaki’s personality balances a duality of insecurity and resolve. Early struggles with self-doubt stemmed from mission dependency and wavering conviction, but her alliance with Shinra Kusakabe and Company 8 nurtured self-acceptance. Fiercely loyal, she shields allies like Iris from Assault in the Netherworld and channels protective instincts toward children. Though prone to tsundere outbursts, her core radiates empathy and justice. In combat, Nekomata augments her agility, speed, and mastery over flames. She wields fiery tails for offense, defense, and emergency signals. Training under Benimaru Shinmon unleashed latent potential, granting techniques like full-body flame armor and expansive fire constructs. Despite proficiency, battles often pivot on her "Lucky Lecher Lure" disorienting foes—a quirk some argue overshadows her tactical skill. Her evolution spans pivotal arcs. Post-Rekka’s betrayal, she vowed to transform into a proactive guardian, emblematically merging her Fire Force uniform with a nun’s habit to honor dual roles as warrior and spiritual anchor. During the Chinese Peninsula crisis, she showcased crisis leadership by soothing allies through gas-induced hallucinations and safeguarding Juggernaut. Later Netherworld clashes saw her resilience shine, repelling Knights of the Purple Haze and aiding critical missions with sharpened tactical acumen. Tamaki’s journey traces her navigating societal pressures while forging self-identity. Initially conforming to external expectations, she embraced autonomy through independent training and confronting insecurities. A defining moment came when ritualistically shedding her turnout gear against Assault’s doppelganger, signifying embrace of both flaws and strengths as intertwined facets of her growth.
