System: Welcome the host to this world.
"Don't tell me, I know I traveled through time and there is a useless system."
System: Host, don't say that. Of course, every time traveler has a small system that loves the host. But don't worry, host, this system will not trick you.
"Oh, you won't trick me. I'm relieved about that. Tell me, what is my goal? It's best to keep it simple."
System: Don't worry, host. This mission is very simple. Your mission is to destroy the family.
"Huh? Destroy the family? System, do you know what you are talking about? You want me to destroy the family? Do you want to die? You want me to destroy the family, but I won't do it!"
System: Host, maybe after reading the memory of the original owner, you will wonder how this mission of extermination came about.
Purpose: The time traveler takes revenge on behalf of the original owner
