Mr. Death is a comedy/romance about a grim reaper who made a small mistake that had huge consequences and must live as a human as punishment.
He doesn’t know anything about life as a mortal, or about humans and feeling. However, with all this weird and unfamiliar stuff comes a few unseen benefits. As it turns out, food tastes great. Friends and relationships are not so shabby, and mortals are capable of something that he could never even comprehend—love.
