Tuka Luna Marceau is an elf and the sole survivor of her tribe in Rodo Forest which was annihilated by the flame dragon's assault. She is later rescued by the Third Recon Team.
Tuka is a girl who appears around sixteen but she is one hundred and sixty five years old. She has long blond hair and blue eyes. Being an elf, she has noticeable pointy ears.
After she was rescued, Tuka wears a white t-shirt folded on sleeves and on the stomach part revealing more skin plus a red scarf around her neck. She also wears blue pants and tennis shoes.
Tuka is seen having a cheery and upbeat attitude but is later seen having psychological issues after she was rescued. She is suffering from her father's death which she stubbornly refuses to accept.
Tuka was living with her father, Hodoryuu Rei in Rodo Forest, a settlement of elves. The forest, however, was later attacked by a rampaging flaming dragon killing everyone on its wake.
Tuka survived because her father protected her, pushing her to the community's drinking well. She remained hidden in the well until Itami Youji accidentally hits her with the well's pail.
