Charlotte

Charlotte (シャルロッテ) is the court magician of the Kingdom of Belfast.

Appearance
Charlotte is a beautiful young woman with an hourglass figure, she has long teal hair and lime green eyes and wears clothing befitting her status as the royal archmage.

Personality
Charlotte is a passionate woman with a thirst for knowledge. Although not confirmed, she may have masochistic tendencies, hinted at a scene in the series when she blushed while Leen revealed that she used borderline torture when disciplining her.

History
She is known to be Leen's magic apprentice before being the official royal court mage of the Kingdom of Belfast.

Touya Mochizuki
Charlotte sees Touya as a gateway to learning new knowledge thanks to his vast repertoire of spells that can be used to help her research.

Leen
Leen is Charlotte's master and is supposedly the one who has taught her everything she knows about magic. Leen has a times been shown to mistreat and punish Charlotte from time to time if she withholds information or does not do something that should be obvious. As such Charlotte's is afraid of going against Leen and will do anything to please her master even if it puts others in unfortunate situations in the case of Touya, for example Charlotte once withheld information from her master and she was punished for it(though Charlotte noted that it was a good lesson and was blushing when she said this). Their relationship seems more akin to a Master-Slave relationship instead of a Teacher-Student relationship.

Abilities
As the court magician of the Kingdom of Belfast, Charlotte is presumably one of, if not the most powerful and skilled magicians in the country. She has an aptitude for 5 elements: fire, water, earth, wind and light.

She appears to know the ancient Partheno language and likely other ancient languages.

After Touya taught her spirit magic and creating a contract, she's able to summon a spirit from the wind family, Sylph
