A freeform adaptation of a classic sci-fi novel by Hiroyuki Morioka. This is the story of Jinto and Lafiel - the unlikely "couple", brought together by chance; an imperial princess, and a son of a nobleman, who gained his rank by treachery. They get involved into the first acts of the war to end all wars - the final conflict between the huge Humankind Empire of Abh and the Alliance of Four Nations.
