Tuka is a girl who appears around sixteen when she is in fact one hundred and sixty five years old. She has long blonde hair and aquamarine 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.
