The groundbreaking revelations that drew Camille and Miep together are yet to be fully brought to light. The two young women present an ultimatum to Urasawa and the billionaire Grynson.

The revelation of the Alter Ego secret has shaken up the entire world population, that is now more or less divided into three categories: those who believe, those who don't, and those who've chosen sides for other reasons. This is the case of Delia, a high-flying lawyer who has decided to vehemently refute the Alter Ego theory. But behind her skepticism hides a secret wound, driving her forward...

Following the great revelation of Alter Egos, crooks and visionaries of all sorts are making the very most of the uncertainty that still lingers around this new-found truth. Gail Llewellyn, the man responsible for evaluating the validity of the Alter Ego theory, travels to Singapore accompanied by his mistress. Gail, who got his job thanks to American pressure on the UN, knows that they are expecting him to sway the Committee's deliberations towards a negative conclusion. He's not too bothered by this, since he himself is somewhat skeptical about the Alter Ego theory. That is, at least, until the day he finds his life indebted to a young woman mandated by his own Alter Ego. Whether he likes it or not, for Gail, choosing his truth becomes a question of life or death.

But which version of the truth will humanity accept? Who will pass the final verdict?
