Master Liber is the Paladin Class Headmaster of the now destroyed Liber Academy. She is presently a member of Iscariot and is the closest thing seen to the group's leader thus far.
She appears to be very respectful and even playful, perhaps even as much so as Biblia's headmaster. Despite being a member of a group openly opposed to the Magic King, she praises Arata's development as one and even seems happy to see him growing more powerful, or at the very least acknowledges that his improvement is their failure rather than anything else. She even appears to be supportive of Arata's desire to take Hijiri back from her, openly edging him on despite stating that Hijiri is a weapon they're using against him, she appears to respect him as a person who'd even fight for the very woman whose purpose it is to kill him.
She gets along quite well with her colleague, Biblia's headmaster, and even engages in playful discussion with him while their respective students are fighting to the death right in front of them.
Master Liber is short and slender, with pink hair that ends in curls. Her eyes are a darker shade of pink, or even red.
She was formerly the headmaster at Royal Liber Academy, but has since joined Ish Kerioth, it is not known whether she played any part in destroying her former school, or if she joined Ish Kerioth before or after becoming the headmaster there.
She seems to be acquainted with Biblia's headmaster, likely meaning their schools communicated or they met before rising to their current occupations.
As a Paladin, she is assumed to be as powerful as Biblia's headmaster, a fact he himself regularly confirms. The two have yet to be seen fighting, preferring to let their students do that, not out of laziness or malice however, but because the sheer idea of two Paladin's fighting could cause serious damage to the world itself, which, given the group she's affiliated with, is putting the means before the end and doing the Magic King's job for him.
Summon Astrology - Master Libel's magic. Other than divination, she can also summon evil god army of star spirits to fight for her (from Liese Chronicle).
Summon Ars Paulina - By using her own blood as a catalyst, she is capable of summoning a creature that appears as a mass of floating liquid with many eyes that allows her to predict the future. It may cause some damage to her if used for a period of time, though.
