Als ein Mann, der auf der Suche nach einer seltenen Briefmarke ist, die Asogi Consulting beauftragt, häufen sich die Leichen. Während sie versucht, sich einen Reim auf den Wahnsinn zu machen, begegnet Rin einem tödlichen Engel, der durch die Straßen streift.
One year after the Aoyama Pharmaceutical incident, Rin is hired to track down a rare postage stamp and visits an old homeless man she calls "Sensei" to gather information on it. He is revealed to possess one himself but it is stolen soon afterwards and he is severely injured. As Rin looks through his belongings, she is attacked by Laura who quickly detonates a suicide bomb. Meanwhile, Maeno meets a girl named Yuki who is looking for an "angel" that may know the whereabouts of her missing brother Shōgo. Attracted by the explosion, he finds Rin's mutilated body and is visibly shaken by witnessing her regenerate. Later, Mimi explains to him that both Rin and herself are immortal because of the "time spores" inside their bodies. In the meantime, several people including Rin's client are murdered and before long, she confirms that Yuki's brother turned into an "angel" due to contact with time spores leading him to commit the recent murders as acts of revenge. She also reveals that angels are natural enemies of the immortals like herself: in their presence, immortals are overcome with lust and angels use that time to devour them. Rin then deduces who Shōgo's final victim would be and confronts him only to seemingly give in to sexual desire. As the angel starts feasting on her, she manages to kill him. An apparition of Eipos, a demigod appearing briefly throughout the series, emerges nearby to claim Shōgo's time spore but Rin gives it to Maeno instead and he, in turn, to Yuki. In the final scene, Rin returns the stolen stamp to "Sensei" who laments how his life was wasted on it.
