Moona is a shy girl, that never really take any initiative, letting Lucia do everything most of the time unless she's forced to do it. She's really kind and love her big sister a lot. Within Akasen, she's slowly learning how to be independant from her old mother, still being a mommy's girl at 50 yo.
Short Story
Moona lived all her life with her mother Natalia, dependant of people due her inability to go beyond her shyness, always hiding behind Lucia when she was here. When she discovered the storybook of Birthgiving Island, it woke something inside of her, a need to be part of it. So she decided to go for Akasen with her mother to find Lucia again, and live the happy life this book was foreshadowing. Thinking that, maybe the incestuous past of their ancestors was still something buried deep inside of them, unconsciously.
