In the manga, Umi resigned from the Kendo club to become an idol. In the anime, Umi remains part of the archery club and becomes an idol.
In all, Umi is trained in many forms of martial arts as well as things such as traditional dance and flower arrangement. While it is never truly depicted, she's from a rather traditional and likely quite wealthy family. Umi, Maki (clearly), Eli, and Kotori all seem to have affluent families.
