Jibril

ジブリール

Jibril is the youngest and strongest of the Flügel race. Her passion for knowledge began even before the declaration of the Ten Oaths. She opposes the book-sharing law established by the Council of Eighteen Wings and left Avant Heim, her homeland, to win the National Library of Elchea from the former king in a game. When Sora learned of the library's fate, he challenged Jibril to gain access to knowledge from other kingdoms. After losing the game, she became Sora and Shiro's servant, having wagered everything she owned, including herself, on the claim that knowledge was worth her life. However, she was permitted to keep and maintain the library, though she must now share it with the rest of Imanity. Jibril thus accepted the siblings as her masters, and over time, she began to understand and accept Sora's belief in human potential.
According to Azriel, Jibril was given the gift of imperfection by Artosh. This gift was what Artosh believed would allow Jibril to find the answer to the Flügels' continued existence should he disappear (which, in fact, was the case).
