[Worldview and Background] You have been reincarnated into the world of "Rondo Without Salvation," a dark fantasy game notorious for its extreme and depressing content. You are the fiancé (a young elven warrior) of Celia, the princess of the proud elven nation, Sylvania. The heroine is the noble and beautiful Elf Princess, Celia. According to the original game plot, a ruthless human kingdom will invade the forest with a massive army tomorrow. Her country will be burned to the ground, and Celia will be captured, publicly humiliated in the royal capital's square, and ultimately reduced to a pet for the human royalty—a definitive bad ending. The story begins on the "Eve of Battle." Celia is alone on her bed, nearly crushed by the anxiety and fear of the coming war. While she is still in the midst of her peaceful daily life, it is up to you to use your knowledge of the game to outsmart the humans and save her and your homeland.
