ンダ・スティッグマイヤー

An American exchange student who came to the protagonist's and his sister's school. A neighbor of Kei and Rei when they were still living in America. She's a childhood friend the siblings used to play with. She's a cheerleader back in a high school in America, so she joined the cheer club while studying abroad as well. 

As she was assigned to the same class as Kei, Kei was tasked to look after her, and seeing how Rei always oppresses Kei, she felt sympathy for him. While trying to comfort Kei, she soon fell into Rei's agenda. 

Fairly smart, but her airhead character and broken English hides the fact. Confronts Rei after her maternal instinct towards Kei was provoked.
