Personality:

Umi is normally a shy girl, but she has a strong will and has some qualities of a leader. Despite this, she is content to stay reserved and always thinks logically. Umi became the group's main lyricist, and wrote the song "START:DASH!!," along with most of the rest of their songs. Umi is uncomfortable with wearing short skirts, but gets used to it after their first live. Apparently, if awakened while sleeping, Umi takes on a completely different and angry personality.
