"Sisters" (姉妹, Shimai) is the 65th chapter of the One-Punch Man manga series.
Do-S manages to hit an injured 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 to 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 the monster 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. Tatsumaki finally arrives and immediately tell Fubuki to go home and that she will handle the rest. Do-S orders her love slaves to attack Tatsumaki as a distraction as she escapes. Tatsumaki immobilizes all of the love slaves and tells Fubuki that they will only get in her way and to not call them her allies. She then takes off to find the rest of the monsters.
- By using the unconscious bodies, Tatsumaki writes ashidematoi, which is a Japanese expression referencing to someone who is a burden or hindrance and holds you back.
