Alias: Sisti/White Cat/Shironeko/Sistina
Sistine Fibel is obsessed with magic—specifically, she's determined to solve the mystery of the Flying Castle, something no one's managed to figure out yet. She's an Air Magic specialist, and she's genuinely talented at it. The whole thing stems from a promise she made to her grandfather when she was younger. After he died, that promise became her driving force, pushing her to constantly improve her skills.
She's got striking looks to match her serious personality: long silver hair, olive-green eyes, and she practically lives in her school uniform. But the beauty is secondary to her sharp, no-nonsense attitude. She doesn't tolerate slacking off, which is exactly why she couldn't stand Glenn Radars at first. His lazy demeanor rubbed her the wrong way, and she assumed he was as incompetent as he seemed. That changed once he actually started teaching—turns out he's genuinely skilled, and she had to grudgingly respect that.
Beyond magic and academics, Sistine is genuinely close with Rumia, who was taken in by the Fibel family. She looks out for her and tries to be there whenever Rumia needs support.
