'He'd come to realise that it was a mistake to grind up his father's remains with such a thing. The mortar was lined with narrow grooves, a little too perfect for ashes to get stuck in.'

Divorced and cut off from his family, Taro lives alone in one of the few occupied apartments in his block, a block that is to be torn down as soon as the remaining tenants leave. Since the death of his father, Taro keeps to himself, but is soon drawn into an unusual relationship with the woman upstairs, Nishi, as she passes on the strange tale of the sky-blue house next door.

First discovered by Nishi in the little-known photo-book 'Spring Garden', the sky-blue house soon becomes a focus for both Nishi and Taro: of what is lost, of what has been destroyed, and of what hope may yet lie in the future for both of them, if only they can seize it.
