Nikka Koudowina

Nikka is Touru's childhood friend and a giant from the orc race. Back at the time when they were palying together (during their childhood) Nikka was around Touru's size (actually a bit smaller) and was hiding her identiy as a giant. She then suddently left without leaving a notice because she was reaching puberty (period during which giants grow up and reach become bigger than humans) as she didn't want to reveal her Identity to Touru, afraid he would be scared of her.
