An exchange student named Rei attends Heartland Middle School and adores Yuma Tsukumo. His catchphrase is "think positive." Despite his friendly demeanor, Rei's behavior can be fan-boyish at times. Ray, on the other hand, has a bubbly personality that sometimes annoys others due to his loudness. He is also very eager to please and tends to rush into things without thinking twice, resulting in clumsiness. Although he means well, Rei often causes problems or makes situations worse.
