Tsubasa Kazanari is a Japanese female born on May 25, 2025. She stands 167 cm tall with blue hair, indigo eyes, blood type B, and body measurements of B81/W57/H83. Her zodiac sign is Gemini. She belongs to the Kazanari family, with Fudo Kazanari as her biological father (raised as her grandfather), Yatsuhiro Kazanari as her biological half-brother (raised as her father, deceased), and Genjuro Kazanari as her biological half-brother (raised as her uncle). Initially aspiring to be a pop star while honoring her family's swordsmanship heritage, she struggled with shyness and low self-esteem. Her first encounter with Kanade Amou involved visible nervousness, but they formed the idol duo Zwei Wing after both obtained Symphogears. Tsubasa deeply relied on Kanade as an emotional anchor and role model, helping her overcome personal doubts. During a concert attacked by Noise, Kanade sacrificed herself using her Superb Song, dying in Tsubasa's arms. This event profoundly impacted Tsubasa, leading her to adopt a cold, aloof demeanor. She began viewing herself solely as a weapon against Noise, rejecting emotional connections and refusing international music contracts. She attended Lydian Music Academy and operated under the Mobile Disaster Response Corps. Her initial hostility toward Hibiki Tachibana stemmed from Hibiki possessing fragments of Kanade's Gungnir relic. Tsubasa slapped Hibiki when suggesting she could replace Kanade. However, after nearly dying from her own Superb Song and a spiritual encounter with Kanade, Tsubasa started emotional recovery. She apologized to Hibiki, Genjuro, and Shinji Ogawa for past behavior, gradually reopening to others. She resumed global music contracts and demonstrated protectiveness toward comrades while maintaining the Kazanari sentinel ethos. Despite this growth, she retained bluntness in communication and occasionally reverted to coldness to prevent others from life-threatening actions, such as Hibiki's overuse of Gungnir. Tsubasa exhibits notable absent-mindedness, attributed to her father. This includes neglecting room cleanliness and misunderstanding everyday concepts like mosquito repellent use or rock-paper-scissors gestures. Her intense focus on music and combat often overshadows self-care, contributing to occasional social obliviousness, such as unintentionally implying weight gain to Maria Cadenzavna Eve. She also expresses surprise at her celebrity status, particularly regarding non-musical appearances. Despite these traits, she displays tactical intelligence in combat and mechanical aptitude with her motorcycle. As the first documented Symphogear user, she wields the relic Ame-no-Habakiri, a Japanese sword linked to Shinto mythology. Her Armed Gear manifests as various blade forms, including katanas, daggers, or buster swords. Combat techniques include "Blue Flash," "One Thousand Tears," "Heaven's Wrath," and "Soaring Phoenix Slash." She can modify her Gear's version and employs ninja skills like Shadow Stitching, learned from Shinji Ogawa. Her motorcycle transforms into a supplementary blade. She activated her relic at age five and received a government driving license at sixteen. In spin-off media like Senki Zesshō Symphogear XD Unlimited, an alternate version features shorter hair and a more cheerful, tomboyish personality. This variant affiliates with Kagemamo and retains the same relic. Tsubasa maintains strict physical discipline, avoiding food past 9:00 PM for figure maintenance. Her musical repertoire includes enka and songs referencing swords or Kanade, such as "Moonlit Sword" and "For You, My Wind."
