Shin Kagami

Within the NPO known as Blue Ship, Kagami occupies the role of guiding mind and, by most accounts, the organization's originator. His doctrine fills a book titled Alert Status Red: The Human Species, whose readers make up most of the membership gathered around him, disciples drawn to the ideas laid out across its pages.

His central ambition is grim in its logic. Standing inside a sealed biotope he treasures as a model of equilibrium, he dreams of engineering a lethal virus and loosing it on humanity, thinning the population so that a new and balanced world can rise from what remains.

Kagami's downfall springs from his clash with Daisuke Matoba over what Blue Ship is really for. He accuses Matoba of hollow commitment, of caring nothing for the cause and everything for the profit in peddling their engineered virus to buyers stretching from Russia to the European Union to the Middle East. To Kagami, exactly this breed of greed is the sickness they exist to cure.

The confrontation ends the same way in both tellings. In the film, Matoba answers the rebuke by stabbing him and throwing the dismissive words back at him, after which Hatsune Misawa treads on the fallen man and mutters that death awaits all of them regardless. The novel hands the killing to Hatsune directly, who drives a stiletto into his heart and tells him to rest. Matoba frames the loss as unavoidable, privately satisfied, certain the doctor's creeping doubt would have spread and rotted the group's resolve.

Blue Ship operates as a non-profit on paper while pursuing apocalyptic ends, and its membership is built from readers won over by Kagami's writing. Daisuke Matoba emerges as its dominant figure once the founder is gone, the pragmatist who would rather auction the virus than release it on principle.

Among the others orbiting the group is Hatsune Misawa, the woman whose blade ends Kagami in both versions of the story. The organization appears in the feature L: Change the WorLd and the novel that adapts it, where the surviving members carry the doctor's plan forward without him.
