Also known as: 幻月, 겐게츠
The second Extra stage boss of Lotus Land Story. After her sister Mugetsu (Touhou) is defeated, Gengetsu rushes to her aid, while admitting that she doesn't even know why the heroine is there. Little is known about either her or her sister and they appear to have no importance to the story. Extremely infamous for one of her final bullet patterns being very difficult to time out as it becomes increasingly more complex the longer the phase continues. This is often referred to as “Gengetsu Rape Time”.
Like her sister, she has Yellow Eyes, medium-length yellow hair, a Red Bow in her hair, wears a pink and white Dress and a Red Vest. She also has White Wings that resemble an angel's wings.
