Sistine Fibel (システィーナ＝フィーベル Shisutīna Fīberu?) is one of the heroines of the Akashic Records of Bastard Magic Instructor series. She admires magic greatly and wishes to discover the secret of the Sky Castle of Melgalius, which no one knows. Her admiration of magic is something that Glenn Radars used to have until he was forced to use his to kill, after which he lost his admiration.
Sistine is a stunningly beautiful woman with long silver hair and olive-green eyes. She has a very similar appearance to Sara Silvers.
Sistine Fibel maintains a strict, no-nonsense demeanor personality and often scolds Glenn Radars for his lackadaisical attitude. She initially hates Glenn, believing him to be as incompetent as he looked due to his lack of enthusiasm, however when he started teaching, she wanted to refuse but she accepted what a good teacher he was.
When Sistine was younger she promised her grandfather that she would unravel the mysteries of the Sky Castle. Her grandfather's death fueled her desire for learning and honing her magic skills.
