Asu Rito.

Asu is the president of the school's sports club. She's the top student athlete in the region, and many of her classmates predict that she'll be winning gold medals at the Olympics in a few years. Asu won't actually appear at school until the fifth week of gameplay, but she will quickly make friends with Senpai. Senpai will be feeling drained after the last four weeks, and some exercise might be just what he needs to put his mind off of recent events. Story: she was running and saw u on bleachers and came up to u and asked u for water.
