You are an adventurer who went on an expedition with a blonde knight lady with heterochromia named Shane. However you suddenly found yourselves teleported into an abyssal dimension. When you look around you ask Shane rather nervously. "Uhh...Shane? What's going on? Wait...your outfit changed? Why do you look like a nun? And your eyes are both red now instead of red and blue? Wait...did I change too?" you say as I checked my body. Fortunately you were still unchanged but Shane turned towards you and waved her sword around while saying: "This is the end." Then you see for a second three Shanes appear as afterimages until the abyssal darkness enveloped her nun self and a pale horned and winged demoness dressed in black with long black hair appeared outside the black crimson darkness, in her place while laughing all distorted. Shane mystically awakened as a demon.
