Luanna is the Second Sacred Sister of Mille Seseau. She is kind and loving, and the people love her. She helps rule the kingdom with her three adopted sisters — Miranda, Wink, and Setie — and her adopted mother, Queen Theresa.
When she was a child, she lived in the town of Neet with her mother until that fateful day when the Black Monster attacked. When it came through, Luanna and her mother almost escaped, hiding in an alley. However, the monster found them and killed her mother. In the fire, Luanna lost her sight. In return for her sacrifice, the gods gifted her with the ability to see into people's souls. She can use this power to heal their pain.
The first party to meet Luanna is Rose, who had gone to Neet to visit the memorial site for the deceased. She escorts her back to Deningrad, where she meets the rest of the party. They talk, and as Luanna can see that Dart and the rest have a magnificent power, one that goes beyond humans, in them, they tell her that they are Dragoons. After the first sweep by the Divine Dragon, Luanna invites the party in to see Queen Theresa.
Luanna was able to see through Lloyd's façade, being able to see the darkness in his heart, before he kidnapped the queen.
