50,000 years ago, Hell was destroyed because of too much Foul from the resentment of the souls that later turned to Soul Eaters and devoured everything in their wake, leaving nothing of Hell. The gods above in Heaven, in order to take care of the newly-died souls, created the Afterlife Department comprised of grim reapers. Huo Ling was delivering food that day when he met Yi Bing and the guy gave him a warning. When he arrived to the customer's unit, he was killed. Huo Ling: you set up a death flag for me! Yi Bing: I'm a grim reaper. I'm the flag myself. Let me help you solve the mystery of your death. Huo Ling: your sister! Alternative title: The Different Ways I Died at 23 Update: daily
"Don't fret. It was me who set the condition of locking your memories during the day, so you won't be exposed. You can only return as a grim reaper during the night." Yi Bing explained when he saw Yang Jie is in low spirits.
"Boss Yi doesn't need to explain everything to me. I understand." Yang Jie answered.
Silence fell upon them for a while. Yi Bing continued to gaze at the city blanketed by the darkness, where only the lights coming from different kinds of establishments illuminated it.
Yang Jie is one of Yi Bing's former assignment. In fact, Yang Jie is his first assignment when he became a grim reaper. Yang Jie died by committing suicide. Yi Bing, as a newbie, was flustered because he found out that Yang Jie didn't have any attachment.
