S1.E1 ∙ Youthful Prelude

The year is 1945. Everything as usual in the Fukuoka city. Some places in Japan have already been scorched by the fire of war, but here it is relatively peaceful and calm. The school still working, and the boys play war in their spare time. Daichi and his friend are the commanders of rival squads. One day a newcomer appears in the class - Yoriko, a girl evacuated from Tokyo. Yoriko takes life very seriously, she has good reasons - her childhood ended after the loss of loved ones in the bombing. Children get to know each other and become friends. They, as the rest of the city, do not yet know that on June 19 their life will be divided into "before" and "after".

During World War II, a teenage Jewish girl named Anne Frank and her family are forced into hiding in the Nazi-occupied Netherlands.

In 2086, Earth's axis tilted 90 degrees and after three years span, approximately ten billion people died. One million colonists who had moved to the moon prior to the disaster escaped what later became known as "The Great Fall". At the moon, they established the Panhuman World Government (PWG) and organized the recolonization of the world. Seven locations were chosen for cities as starting points for this massive project. To guarantee their authority over the new colonies, the PWG built a highly advanced defense system on the moon called Olympos-System. In 2136, the lunar government perished due to an unknown virus brought to the moon by a meteor, but the automated Olympos-System remained active and has a life span of about 200 years. It is 2190 and some of the Seven Cities wage wars against each other. Two talented military strategists from opposing cities rise to confront each other.
