Biography
EE Jump was a Jpop duo made up of Sonim and Goto Yuuki (Maki Goto's younger brother). The group proved to be very quirky and sometimes downright weird, but their combination of pop/opera/rap/hillbilly-music proved to be very popular.
After Yuuki was caught in a bar underage, he was to take a 3-month leave from the group. During this time Sonim released a single as EE Jump featuring Sonim which was EE Jump's most successful single. She released one more single before the band officially disbanded.
