Ep. 18: Licht slaughters enemies during the Waste War while Schmelman creates the floating utopia of Alcia.

The Waste War begins. Rihito, now Licht, begins slaughtering thousands of the enemy, hiding his face behind a mask. Four of his classmates receive the Ace surgery, Sakai, Doan, Sonohara and Captain Alan. Schmelman decides the world is beyond saving and begins planning a utopia called Alcia. Rihito eventually goes insane and severs Sonohara's left arm. Two years later, the war ends when Schmelman, having now retrieved all seven ballots, uses them to create Alcia floating above the ruined planet. He destroyed all means of contacting the surface and creates Alcia's population from the DNA of all races and kept the population in check by sending anyone with a 0 ballot count to the abyss, revealed to be a portal to the planet's surface. It is also revealed Althing sustains Alcia by continuously stealing resources from the survivors on the surface. Learning this Sakai stole a ballot, so Rihito killed him on Schmelman's orders, but murdering his brother sent him into a coma. After he finally woke up he learned every member of his class remained on the surface and committed suicide. That day, he and Nana escaped Schmelman and for 300 years Licht never removed his mask and barely spoke, even to Nana, until he met Hina. Nana reveals to a returned Hina she was worried Licht had decided to destroy Alcia to save the planet, risking his own life. She had always known it was impossible for them to change the past, but hopes they have learned how to save the future. Hina approaches Licht, offers him her breasts and tells him to continue where they started 300 years ago. (Source: Wikipedia)
