After waking from a long cryogenic sleep, high school student Akira Himegami finds himself in a world he no longer recognizes. The city lies in ruins from war, society is now governed by an organization called OWEL, and traditional marriage has been replaced by a new system known as "Elsie." As Akira struggles to comprehend this drastically changed future, a familiar figure appears before him—Yuugure, who bears a strong resemblance to his girlfriend Towasa. To his shock, Yuugure smiles gently and proposes: "Akira... please marry me."
