[Atypical quick travel, a two-person travelogue to a different world (beginning of Chapter 6?). There shouldn't be any bitterness or hatred, just some adventures in a wonderful world?
You wake up and the world disappears.
A cat that I have had for a year:
"I'm leaving, man, take care of yourself."
A friend I haven't seen for many years:
"The task of saving the world is left to you."
A stranger whom I have just known for eight hours:
"My life is in your hands."
A cartoon bird claiming to be an assistant with power:
"Saving the world is very simple. As long as you stay mentally healthy and alive, you can wait for the battles in other world lines to end."
You: "I don't have to do anything?"
"You have worked very hard in other worlds, and your peace of mind is the greatest help."
[This is the product of the neighbor who wanted to set up and thought about it. Only the "grey sea" is related to this story. Free writing begins. The author does not know much more about the plot than the readers. I don't know where the bottom of the pit is. Feel free to jump and read XD]
Purpose: Free writing, text adventure
