As the rebel leader, Retsumi commands one of the sides striving over control of the Eighth Region Hod. However, in truth the conflict was instigated by Retsumi after discovering her friend Kareha's slow transformation into an Empty. Desperate to save her friend, Retsumi asked Kareha what would provide her with motivation to keep living. After Kareha answered that it was through fighting Retsumi, she founded the rebel army in hopes of saving her friend. Like Kareha, Retsumi doesn't like the life or death battles that predominate the Tenth Region Malkuth. As a result, both sides agreed to a non-lethal war where bullets were traded for water guns and defeat would be determined if a poi sheet of paper on each Quasi-Spirit's body was successfully struck.
