Tia

Tia is one of the four playable characters at the beginning of the game "Lunia Z".    
 
She is a Half-Elf who has a Human nobleman as father and an Elf as mother. She is on a journey, following the trace of her missing father who was a royal court official and disappeared into thin air. Practically raised herself, she appears to be very tough and independent, but in fact, is tenderhearted. She became a Thief to find the keepsake of her father. She is agile, but physically inferior; to compensate this weakness, she has mastered skills such as creating mirror images and hiding from their detection. Her most skills are capable of finishing enemies with a single hit.
