Spoilers:
She's the crown princess from another kingdom (well 'former' in the upcoming chapters) she also achieved highest tier in magic and she's a very likeable character and witty like Cale and she's like the older sis of the group (▰˘◡˘▰)
She is a mage and also a princess of the breck kingdom. She is a VERY powerful mage and later on renounces her title of being princess and lineage to the throne in order to fulfill her dream of being a mage. She then becomes the master of the magic tower. She’s really cool and I really like her a lot!!!
She has great control in mana and always exceed the limitation of a normal human/mage!
a lot of people like ROSALYN plss spoil me on who she is(づ￣ ³￣)づ
