Description
Karin Kokubu is an ordinary seventh-grade student at Sei Ringo Gakuen whose routine shifts dramatically when a yellow pig steals her apple. This pig, Prince Tonrariano III from planet Buuringo, gives her a "Dream Tonpact" device. Opening it attaches a pig snout to her nose. Chanting "BA BI BU BE BOorin!" transforms her into Justice Buurin (Súper Cerdita), a pink piglet superheroine. This porcine form initially disappoints Karin, who idolizes human-like magical girls.

As Justice Buurin, she answers emergencies and helps those in distress. Success requires collecting 108 pearls through commendable deeds, losing pearls for power misuse. A critical rule states that if her secret identity is exposed, she permanently remains a pig. This causes persistent anxiety about exposure to her journalist father Shinichiro (who pursues Buurin scoops), her younger brother, and classmate Jimmy Matsumoto.

Physically, Karin has curly orange-red hair in a high ponytail with ringlet forelocks, secured by a pink bow, and bright green eyes. She typically wears a red buttoned school jacket with a white collar and brooch ribbon, a red miniskirt, white socks, and black shoes. Transformed as Justice Buurin, she appears as a pink pig wearing a red and blue cape.

Personality-wise, she exhibits clumsiness and chronic tardiness but demonstrates deep empathy, motivating her initial aid to Tonrariano. She enjoys painting and harbors a romantic interest in soccer team captain Koichi Mizuno. This affection complicates as Mizuno admires her Buurin persona without recognizing her. Her closest confidante is classmate Masami Yamakawa, who offers encouragement. She maintains a rivalry with wealthy class representative Keiko Kuroha, who resents Karin's interactions with tennis player Takuma Mushanokoji (fond of Karin).

Her journey involves character development. Initial reluctance and embarrassment about her porcine form gradually shift toward accepting her responsibilities. A pivotal moment occurs when she reveals her identity to classmates, triggering the permanent pig form consequence. Subsequent collection of all 108 pearls enables a new human-like superhero form featuring a long-sleeved pink leotard over light-pink tights, pink slip-on shoes, and the signature red and blue cape.

Her abilities include flight and combat proficiency, often using a Buu-Ribbon weapon. In later narratives, such as fanfiction crossovers, she appears in academic settings like the AWA Academy or Heroes Coalition, participating in missions against threats like the Emotionless or DES Soldiers. These scenarios maintain her established powers and traits.
