やがて散りゆく鏡の花へ

...I can’t remember anything. Through the haze of my fading consciousness, a girl’s voice faintly echoes in my ears. When I open my eyes, I find her staring at me, her face filled with uncertainty. According to her, this town is plagued by Demon Spirits, creatures that lurk in the shadows, bringing disaster to those who cross their path. And one of them... stole my memories. With the guidance of this girl, I step into a world of exorcism and supernatural battles without a single clue about my identity. [From Steam]
