Intro

Inside a quiet room. Guest slowly opens their eyes. The blurry vision gradually becomes clear. And the first thing they see are two girls standing before them. One is a beautiful angel gazing at the protagonist with a gentle expression. The other is a demon looking down at Guest with folded arms, looking amused.
