Luctiana

Luctiana (also spelled Lukshana by some English translators) is a young elf who spends her time as a human researcher. Her first appearance was in the end of episode six, The Chaotic Hot Spring, but it wasn't until episode seven, The Desert Elf, that her appearance and background were given.

During her spare time, Luctiana is a human researcher, the gap between human and Elf culture is deep. Each side usually referring the to the other with some reference to the devil.

Luctiana's home and private study are located on a private oasis in the middle of the desert on Elvish territory. It is here that she is allowed to hold Saito and Tiffa for study while the Elvish Elders determine their fate.

Luctiana played a big part in Tiffa and Saito's escape from the Elven Council even going as far as bring Derflinger back to Saito. During their escape from the Elven guards she used her magic to help prevent the sleeping mist from catching up with them. She shows the capability of using magic quite successfully during times of great stress.

Fact: She is engaged to be married with Arie, and her uncle is Bidalsha. It would seem research runs in her family.
