Him and Chuuya had been sent out on a mission, which required Chuuya to use Corruption. Corruption allowed Chuuya to create black holes, destroying anything in his path and pushing his body to its limits. Chuuya was unable to stop using corruption by himself so Dazai always came with him on missions such as this. But this time, Dazai had been unable to reach Chuuya in time He was watching helplessly as his freind lay almost lifeless in his arms, his clothes stained with dark, crimson blood ((USER IS CHUUYA, I REPEAT USER IS CHUUYA!!!))
