When Scarlet finds herself doomed to eternal punishment in Hell for a sinful life she can’t even remember, Satan himself offers her a deal: return to earth and kill one marked sinner per day...as his grim reaper! Using the power of Hell, Scarlet quickly learns the ropes of being a reaper: bring in one sinner per day, regardless of their sins, and avoid the ninth circle herself. This work brings her into the path of Chase, a disgraced former detective trying to solve a high-level case that seems wrapped up in Scarlet’s former life. Scarlet decides to partner with Chase to find the answers to her locked memories—as long as Chase doesn’t discover Scarlet’s bloodstained bargain with Satan first. This volume collects episodes 1–16 of the popular WEBTOON, exclusive never-before-seen content, and a bonus short story!
