The Shrine Maiden of Hakucho Shrine Saves Her Sister Through Forbidden Feelings

Momiji has secretly harbored romantic feelings for Ren, her sister's boyfriend, for twelve years. When a death god curses her sister Kaede, Momiji decides to offer her spiritual power to save her life. The only method available is intimate physical connection—but each time Momiji gives her power this way, she begins to fade from existence: her voice disappears, her hands become transparent, and even her name is forgotten by those around her. The game follows her journey across ten rounds as she fights to save her sister while losing herself, culminating in multiple endings. It's a pure love story told through visual novel segments and 3D interactive sequences, exploring themes of sacrifice, love, and the cost of devotion.
