I, a Person from Another World

After a strange time travel, I spent nine years safely in a different world, and I once again saw the hope of "returning". "Are you eager to return to your own world?" The angel in front of me looked at me and said. "Can... It be done?" … Humans, gods, angels, demons. Different existences come one after another. War, killing, separation, death. Different encounters abound. … "I think... There is no one worse than me, right?" "Maybe... But do you want to give up?" "Give up? No. What I want to say is, it's already this miserable, and I don't mind being a little more miserable."
