Andrew is quite new to the reaping business, and he hasn't quite gotten it yet. For one, his scythe, the tool of the Reaper, was composed of a material impossible to aquire, and was bonded with him on a molecular level. And his new mentor keeps confusing him with all the different terms he will have to learn. But Andrew pushes on, determined to perform his duty for both Earth and the realms beyond it. Get rid of the spirits on the Earthen plane, release them safely in the afterlife.
But-as he soon finds out-Reaping spirits is only his main duty. There are also strange happenings. Demonic possessions, muses, and sirens wreaking havoc all over the earth, with the eventual goal of overthrowing Heaven, Seoul, and all that lie in between. And as luck would have it, the Reaper is the only chance they have for survival.
