Spiral: The Bonds of Reasoning Vol 12

From the Yen Press edition

Ayumu prepares to leave the hospital, still mulling over the murderous role fate has for him to play. But if Hizumi is destined to die at Ayumu's hand, why does he seem so eager to be friends? Far from bloodthirsty, the good-natured Hizumi has been living in Ayumu's apartment since the Kanon incident and intends to stay on as Ayumu's roommate! Hizumi claims to have accepted the cards fate has dealt him, but can he really be so complacent about his own death?
