Ep. 13: Kanon attacks the train while Gennai dies and Ibuki’s twins are born.

Kanon uses her electricity to power a robot spider, intending to kill Ibara and others so she and her sister can die together, despite Shion’s protests that this is killing Kanon. Ibara defends the train from Kanon’s attacks while Onihei and his men race to the old capital by helicopter. Ibara tries to reason with Kanon, who refuses to listen and hates that humans sent them to a contaminated city to die. After being knocked out by the robot spider, Ibara stops Kanon by using Haruto’s grenade to blow up a water tower above her. Ibara, Aoi, and Oyakata rescue Shion and convince Kanon to live by becoming friends. Gennai dies from radiation poisoning after seeing the sunset. Taeko reveals Ibuki’s twins were successfully delivered. Kanon provides a landing location for the rescue team. Aoi, Ibara, and Taeko give a group picture to the JAXA survivors and name the twins Riku and Sora. Onihei reveals a secret about the Coppelions. The group continues their mission to rescue more survivors.
