Kokubu Karin is a Grade 7 junior high school student attending Sei Ringo Gakuen. She has bright red hair that she wears up as a ponytail and, like the two wisps on her sides, has curly ends that reminiscent to a curly pig&#039;s tail. Karin also wears a ribbon with a blue ball, just on top of the pony tail.    Although Karin is klutzy, she has a caring heart. Because of this she helped Ton-chan in the first place, and that made him 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 caused worries in Karin. Her other worries came from her father, little Shuuhei, and later Jimmy Matsumoto, who are always on her tail when she appears as Buurin.

"Look! In the sky...It's a bird...It's a plane...It's Super Pig?!"<br><br>
One fateful day, Karin, a junior-high student, found what she thought was an injured piglet. However, the piglet was just exhausted from hunger. After the piglet regained his health by eating Karin's apple, he revealed that he is a prince, Tonrariano III, from a planet called Booringo. Tonrariano wanted to reward Karin for helping him and so he transformed her into a pig with superpowers. Karin was not at all pleased with the gift because she wanted to become a pretty superheroine like "Cutey Chao" (a parody of Cutey Honey), not Super Pig. Reluctantly, she became more interested in her role as Super Pig when she found out that she can turn into someone like "Cutey Chao" if she can collect 108 pearls through doing good deeds for other people.
