The Fantasy World of Sinful Spirits

The exchange students accidentally stumbled into the dark side of the world - a different world called the Singularity. On the dark and scarlet streets, twisted monsters were wandering one after another. When there was nowhere to escape, a girl holding a gray-blue sword stopped the monster's attack. From that moment on, the gears of his and her destiny began to turn, surrounding the city of "Issu". This novel and its characters are purely fictitious.
