Noi is very confident and carefree. So carefree that as Shin mentions, later on, she has stopped trying to avoid attacks because she can easily heal herself. Noi enjoys fighting and often competes with her partner Shin to see who can kill the most. Her bold personality can get them both into trouble because she doesn't bother to observe her surroundings carefully. The person she shows the greatest respect towards is Shin. She has a large appetite and she also enjoys fair fights.
