That amazing assignment is none other than to roam Earth for one week and observe how humans have evolved. It's mandatory that every grim reaper fulfills this assignment once every hundred years.
In other words, grim reapers needed to know what's trending in the human realm. What are some of the new technologies they have finally managed to develop and what types of medical breakthroughs they have finally achieved? But as far as he knows, there aren't cars flying and people are still dying from the same diseases. Humans also tend to repeat history and recycle their fashion trends. So, there probably hasn't been that much change since his last visit.
That's why some grim reapers simply find humans a bore and this assignment a complete waste of their time. However, to D209, this is like a paid vacation. In fact, he wished the assignment was longer than a week but he'll take what he can get. It's an opportunity to learn and play, and don't even mention all the food he's going to be able to eat. Because in the underworld, grim reapers don't eat so there is no such thing as food. During his last visit to Earth, he discovered tacos, and those were amazing. And then there's chocolate. He ate so much of that, he made the last person he possessed gain almost ten pounds in a week. So he can't wait to possess another human so he can discover more new food.
However, what he didn't expect was for his vacation, no, his assignment, to land smack dab in the middle of a worldwide pandemic. Hello Covid-19! Everything is closed and humans are under mandatory hiding or quarantine as they called it. So what on Earth should he do now? How is he supposed to report back his findings when there's nothing to see or do?
That is until he found the busiest and most active place during this damn pandemic, St. Bernard Hospital. Now, he just needs to find the right human to possess. Hmm, how about this Asher Jansen?
