Yui(Knot) - The Forgotten Girl is an urban fantasy visual novel, taking place in Japan. The protagonist of the story is Shokichi Namino, a shy and frail man in his late thirties who, after being fired from his job, fell asleep at a bus stop. He wakes up late at night and sees an illuminated road going up the mountain, which he decides to climb. At the top, he finds a shrine and is attacked by evil spirits. Fortunately, the goddess of the shrine shows up in time to save him.  Yui is the goddess of the knot, or in other words, a goddess of marriage. Her temple has been largely forgotten about, and so she spends her days there in loneliness. She invites Shokichi into his temple and spends time with him, eventually using him to satisfy her sexual desires as well.
