B-ko

B-ko is said to be the most popular and beautiful girl in the school the characters are attending, excelling in both her studies and sports. She appears nice, cute and cheerful to most people. In spite of her perfect reputation, she has a hidden, aggressive side, that only her three friends seem to know. She is also constantly worried about her image and seems to have somewhat of low self esteem, as she uses a façade to hide her insecurities. Throughout the series, B-ko becomes increasingly anxious and paranoid as she faces her coming death.
