"Seven-twenty?" Keiko whispered.

The bundle contained a ledger, photographs, and a small leather-bound journal. The journal's first page bore Keiko's name in a hand she recognized as the same as the scrap's. The last entry read: "High quality: keep the work precise. The world saves itself one careful act at a time."

Aya produced another scrap. On it, hand-stamped, were the same numbers—1000giri 130614 Keiko 720—followed by a small map dotted with three Xs. "My granddaughter left me these," Aya said. "She vanished ten years ago. Before she did, she encrypted a message across the city—places she loved. I couldn't decode it. Your name was on her last note."

Years later, Keiko would mark each small rescue into the ledger. She would learn to read the city like paper music—hidden codes under benches, folded messages in ramen bowls, dates tucked into the seams of theater curtains. She would become fluent in the economy of quiet help, where "high quality" meant meticulous care and "1000giri" meant the patient tally of lives redirected.

At a 24-hour photocopy shop two blocks away, a bored clerk fed the reel into a scanner. The screen filled with frames: a young woman—Keiko's grandmother, years younger—played a simple melody on the piano, then spoke. Her voice cracked but clear: "If you find this, know the numbers guide you. 1000giri is the tally; 130614 is a date you must remember; Keiko 720—follow the seven-twenty path."
