After Donquixote Doflamingo's defeat, Gramoo became aware of growing resentment towards the Omoino Family due to their forced involvement with the Donquixote Pirates, as well as a plot to ambush Kilomane. Out of worry for her safety, she began staying inside.
Eventually, Gramoo asked God Usopp for help, and he convinced the ambushers to work on the reconstruction effort instead. Gramoo thanked them and went to inform Kilomane, who thanked the Straw Hats as well. She also reveals she would like to support the local Usopp fan club, Team God (チーム・ゴッド,Chīmu Goddo?) in order to repay her debt to Usopp for clearing up the matter.
