Ihna's vocal range is medium or medium high. 

Ihna can be very blunt and sarcastic at times, she is a moody person and easy to provoke. She often gets into petty fights with Hyesung throughout the game. Ihna suffered abuse at the hands of her father, who wanted a boy and not a girl. As a result, she's tried to bury her past, and the idea that it might be brought up again inspires true panic within her. Inha often tries to act tough in stressful situations to avoid looking like a victim. She easily empathizes with, and attempts to protect "weak" or vulnerable people, while scorning anyone who would bully them.
