I'd like Tana to have a higher pitched, more child-like voice, instead of the deeper and mature one she was given in Heroes.

Tana joins the army in order to accompany her friends and older brother to war, having trained under Syrene and Vanessa. The circumstances vary depending on which path you take: in Ephraim's path, she runs away from home and is captured when she was tracking Ephraim's group after they leave Frelia, but in Eirika's path, she directly goes to Eirika and asks to join her troops.
