Hana's delivery route takes her through an abandoned factory district. Inside a collapsed stairwell she finds a locked sketchbook — and doesn't leave it behind.

Hana tests the sketchbook — her first accidental drawing comes true. She returns to the Nishida district and meets Tomoya Seki, café owner, skeptic, and the only person she risks telling.

Hana discovers whose sketchbook it really is — and what they used it for. The stakes clarify. She must choose: return it, keep it, or destroy it. She makes the only choice she can live with.
