For ten-year-old Kaori Tanaka, the house wasn’t just a landmark of local legend. It was a dare. A test. A monster under her bed that she could see from her own bedroom window.

Kaori’s flashlight flickered. Any rational person would have run. But Kaori remembered something her grandmother once said: “Fear is just curiosity in a scary mask. Take off the mask, and you’ll find a question.”

Kaori had never heard the note. But last Tuesday, on her way home from calligraphy class, she did.

The front door was already ajar—not broken, but politely open, as if expecting her. The air inside tasted of wet ash and old paper. Her flashlight beam danced over a grand staircase, a chandelier draped in cobwebs like funeral lace, and a piano. It sat in the corner of the main hall, its lid closed, its keys yellowed like old teeth.

It wasn't a sound so much as a vibration —a low, humming ache that made her teeth tingle. That was when she decided: Halloween was three days away. If she was ever going to prove the legend wrong (or, terrifyingly, right), it had to be now. Her best friend, Yuki, refused to go within three blocks of the mansion. “I don’t need candy that badly,” Yuki said, crossing her arms.

Silence.
