Fubuki is struggling against Do-S. All of Fubuki's subordinates have turned into love slaves. While Fubuki tries to hold off Do-S's love slaves, Do-S's whip eventually manages to pierce through Fubuki's telekinesis and hit Fubuki. Do-S manages to hit Fubuki multiple times. Believing that she has Fubuki's mind under her control, Do-S approaches Fubuki and tells the hero about her plans to lure Tatsumaki out. Enraged, Fubuki sends Do-S flying back. Before Do-S could get a hold of the situation, Fubuki uses Hell Storm, which slightly injures Do-S. As it turns out Fubuki did not succumb the monster's mind control. Do-S changes her plans and decides to kill Fubuki instead of using the hero to lure Tatsumaki out. Fubuki tells Do-S that her sister would come anyway.Tatsumaki causes an explosion in the city where Do-S and Fubuki are fighting. Do-S realizes the mistake she has made and immediately tries to make an escape plan. A monster falls in front of Do-S asking for help and warns her of Tatsumaki.
