A very serious girl with a brusque personality Asahi is the ace of her school’s basketball team, despite only being a first year. As someone who didn’t have time for anything she considered frivilous, particularly romance, it came as something of a surprise to her when she fell for one of the boys at her school, Medaka Kuroiwa.
Learning that she would have to compete with the school’s most popular girl, Mona Kawai, did little to deter her and she started to pursue Medaka with the same dogged determination she put into basketball. However she is often hamstrung by her nervousness around him.
Though normally terse, Asahi has a lighter side and often displays a sense of humour, and genunely loves basketball. Though Mona and she are romantic rivals, they’ve developed a somewhat antagonistic friendship.
