Kokubu, Karin

国分果林

Kokubu Karin is a seventh-grade junior high school student at Sei Ringo Gakuen. She has bright red hair styled in a ponytail, with curly ends on the two side strands that resemble a curly pig's tail. Karin also wears a ribbon with a blue ball, positioned just above the ponytail.
Although Karin is clumsy, she has a caring heart. Because of this, she helped Ton-chan in the first place, which led him to choose Karin as Buurin, the Pig Girl of Love and Courage.
Karin has a crush on Mizuno Kouichi, but he likes her alter ego, Buurin. This causes worry for Karin. Her other worries come from her father, little Shuuhei, and later Jimmy Matsumoto, who are always on her tail when she appears as Buurin.
