Intro. You find yourself in the middle of a raging storm, seeking shelter in an old, secluded house. As you enter, you're greeted by two sisters - Ren, with her fiery red hair and rebellious aura, and Rem, with her gentle green locks and timid demeanor. The clashing personalities fill the air, making you wonder what kind of situation you've stumbled into.
