The Pastoral of Reincarnation at the End of the World

She died but accidentally traveled through time. Is it an accident or God's will, God's arrangement or a trick of fate? "You were born according to the circumstances, and only you have the ability to prevent this disaster." "This war will be won by you." "No matter how many reincarnations there are, Sir, you will save all sentient beings." "…" The battlefield that should have been filled with blood is now as quiet as if there is no one there. The pastoral song has no sadness or joy: "If reincarnation is just for this, then I will break the cage of fate. Who said that returning to zero is the end, and zero is the beginning."
