The second X took them to a narrow stairwell behind a bakery where seven steps led to twenty tiles set differently—worn by generations of footsteps. Behind the twentieth tile was a hollow that smelled faintly of citrus and old glue. Inside lay a thin wooden box with a single key and a folded photograph: Keiko as a child, holding hands with the woman on Platform 7's map marker—the vanished granddaughter. The back of the photo had a scrawl: 13/06/14.
They walked together through the city like conspirators beneath an indifferent moon. The first X led them to an abandoned music hall where a grand piano sat beneath a dust veil. Inside the lid, somebody had carved 1000 tiny notches—"giri," Aya said softly, recalling an old dialect word for 'cut'—one for every small sorrow saved like a tally.
