With radiation spreading to the Planet in two-three days and preventing the survivors from having any safe passage out, Ibara and Haruto come up with an idea to transport the survivors to safety by fixing and using the city's broken Rail transportation. But knowing the Ozu sisters will come after them once they are free, thanks to Kanon's tacking abilities, Ibara forms two teams; one team led by her will be a diversion for the Ozu Sisters while the others go and fix the power to the railway and escape. With Ibuki experiencing more labor pains, Taeko is afraid of delivering the baby until she is contacted by Granny Ayame by radio who tells her that she will help her deliver Ibuki's baby. As the Coppelions and the survivors prepare to evacuate the Planet for their escape plans, everyone has one last dinner inside the dome where Aoi finally comes out thanks to Mr Nonsense. Before they leave, Ibuki asks the Coppelions to rescue one more survivor, the baby's father, who is revealed to be the 1st Division Soldier who helped Aoi escape. Joined by Aoi and Mr Nonsense, Ibara and Haruto head out to draw out the Ozu sisters while Taeko, Ibuki, Gennai, Oyakata and Gojiro heads to the railway.
