Kazuya Niimi, a student at a music university, is known for having "immobile fingers". Hardly fitting for someone aspiring to be a pianist. One day, due to a sudden twist of fate, Kazuya finds himself lost in another world. In this strange new world, men are not treated as people. It is a society of overwhelming female supremacy and male subjugation. But in that world, Kazuya notices something strange happening to his body. His fingers now hold a mysterious power. Fingers that cause anyone they touch to physically react. Kazuya’s fingertips begin to make this irrational world wet.
