The Undead system - Chapter 31: Killing a rank E fox

After losing his parents in a car accident, Ryan immediately caught his fiancee cheating on him with his best friend. In just a few days, he lost everything he loved, so Ryan decided to buy a house in the mountains to process all those events. However, something happened before he could even enter his new home: the end of the world. Monsters began to appear out of nowhere, and dragons began to dominate the skies. After losing everything, Ryan, who had lost his sense of reality, found new goals with the world in that state: survive and get stronger. Dungeons, classes, monsters, skills, the chance to obtain the DNA of other monsters... Ryan was decided to use them all because he no longer would become a spectator in his own life.

She was originally a puppet of her family. Pursued by the police for being a business spy and hitman, she was betrayed and fell into the sea.
