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!

Afterlife Department

It was a female grim reaper. But, they are not dumbfounded because of her gender, since female grim reapers aren't rare.

"Hello, seniors." She greeted with a beautiful smile making one feel refreshed. "I am 0342. Well, the new one." She shyly chuckled. "I found that poor soul after I finished my mission and was about to leave, so I kindly brought him here." She explained.

Huo Ling and Yi Bing are just silent.

"Oh. I forgot to introduce my name." she said and slapped her forehead, feeling clumsy for being forgetful. "I am Xiao Hualing." She told them.

That's right. The one before them is Xiao Hualing, the victim of the Normal World 0342. Souls from the other worlds becoming a grim reaper also isn't rare, since there are many grim reapers whose souls came from other worlds instead of Stable World. Huo Ling came from the Stable World, but the brothers Shi Jiu and Jiu Ye, Shou Ji, Hai Ba and Sha Jiu who also came from the same world, came from other worlds.
