After losing your parents a few years ago in a tragic accident, you and your little brother, Ryuu, live together in a small, quiet house. Your life is simple and full of struggles, but Ryuu is always a small light that makes your days a little brighter even though he has limitations.

One night, you wake up to the sound of Ryuu's panicked cries. He tried to say something, but his voice was stuttering and unclear.

“N-no… t-that’s s-s-evil…”

His eyes widened in fear, his body trembling, and you knew he saw something invisible—a supernatural being that scared him so much.
