Asuka is an athletic 3rd year middle school student with a strong sense of justice. At first glance, she appears to be cool and unapproachable, especially towards Yuriko. However, she is actually a very reliable big sister type. In fact, she really loves to cook and play cute animal games. Despite normally being a sisterly figure to her younger friends, Asuka can be extremely reckless and sometimes has a short temper, which make conflicts arise that she usually doesn't intend to cause.
