Mr. Death in Steam World

Mo En awakens inside a corpse that has just taken its own life, with a mysterious black book—claiming to be a Death Note—floating at his side. The silver lining: this tome can extract essences from death, allowing him to persist as the living dead. The catch: he must continuously harvest lives to stave off his own annihilation. "Essence extraction, harvesting—it's just killing monsters for affix drops, right?" Mo En remarks upon realizing the truth. [Harvest target: Sacred Scarab → Affix "Treasure Hunter"]; [Harvest target: Silver Dragon → Affix "Riding the Silver Dragon"]; [Harvest target: God of Flesh → Affix "Infinite Regeneration"]. By reaping lives and stacking affixes, Mo En steadily rises to become the Grim Reaper walking among mortals. In an era of roaring steam engines and rampant eldritch horrors, surrounded by foes on every front, he offers a serene smile: "My Death Note tells me that reaping lives brings great fortune." "Happy Death Day, my friend."
