Rosalina was born in another land outside of Caerundal, supposively known as Hikugami. She was sent to an adoptive family in this land as an infant for an unknown reason, her sister following her for the same reason a year or two later. It is assumed her and Lucilla are from the same place and original family. It isn't known exactly what caused her adoptive parents to outcast her when she was sixteen, but she blames it on how she started to suddenly grow wings. Her sister followed Rosalina as she left, not because Lucilla herself was outcast, but because she was loyal to Rosalina.
Unknown to most, Rosalina used to be a rather shy and timid woman with her heart deadset on researching and using her potions to benefit others. Her earliest friends know this, but seem to have forgotten or not care. After a series of unfortunate events, her mind just cracked and she broke down, going on a murderous spree of bloodlust which resulted in a few injured people. This, ontop of other things to come like having to deal with new truths and her new personality disorder, caused her to lose most of what she was, and instead become a rather sorrowful alchemist with no real goal in the world anymore.
Too much has happened to Rosalina to be properly documented, but she has gone through several changes in what she is emotionally. She used to be rather lighthearted and talkative, but seems to always have a sorrowful and melancholy, even cold, aura to her now. She has devoted most of her research to try and fix her disorder in any hope of possibly repairing some of the damage that has been done, and try to go back to being more of her old self. She has made many friends regardless of all kinds, and no matter the predicament, they always have succeeded in helping her out of her problems, including the time she even died once.
Luna "Lunatic" ScarletEdit
Luna, better known as Lunatic, is Rosalina's main alternate personality, and serves as a strongly contrasting alter ego. Lunatic is the embodiment of trauma, despair, lust (especially bloodlust), pain, suffering, among other things. She will amuse herself by any means possible, whether it be trying to murder someone or invading the dreams of a person, creating a very twisted nightmare, and feeding off their soul energy, to simply drinking and making rather crude jokes. She doesn't think, she just does what she feels like doing. She is just as intelligent as Rosalina as they are one in the same mind, which makes her even more troublesome at times, though she usually doesn't have the common sense to use her intelligence. She prefers slow, torturous pain over quick, precise damage, leading her to mainly use gnarled, jagged blade or a whip. She can be quite eerily nice at times, but it is quite possible that is due to her unpredictable nature and childishness.
