Hellbringer

In a place which was situated who-knows-where, Death was casually sipping some coffee while reading a book.

Billions of bookshelves surrounded him, each containing many books. In total, trillions of books surrounded him.

These books were known as death books and they contained information regarding a person's death like the cause of death, the one who killed the person, the place of death, etc

Every single person in this universe had a death book and it would open five minutes before their death.

Or at least, Death had thought that every person in the universe had a book. But some people were out there without a death book.

As he was simply drinking some coffee and reading his book, a red alarm started to resound in the library.

He frowned as he put the book down as the shelves in front of him started to change their positions.
