In "YUME", a girl went to the abandoned Dance Hall to record a program in a era of peace, but she became unwell and saw a girl in red who looked just like herself in a trance. Is this girl, who looks so similar to herself, maybe it’s the person from her past life? In the game, you will not play as a warlord or a soldier, but as a tender girl just trying to survive in wartime. Through the deep reveal of some obsolete items that can drive the plot, and the multi-layered switching between characters allows players to experience the girl's past. Whether it's the reincarnation of a past life or the warmth of the present, it's important to recognize which side is reality as soon as possible.
