Claire Kagenou

As the firstborn of the Kagenou household, Claire is Cid's elder sister and a remarkably talented magic swordsman. Despite her own exceptional abilities, she harbors an intense, near-obsessive protectiveness and possessiveness toward her seemingly ordinary younger brother. She was once afflicted by demonic possession, which Cid secretly cured, granting her a vast surge of magical power as a result. In the second season, while journeying to the Lawless City to hunt down the 'Queen of Blood,' she becomes mysteriously linked to the calamity witch Aurora, ultimately serving as a vessel for her soul.
