What Keizoku: Unsolved Mysteries - Beautiful Dreamer is
Susono Station, late autumn, the 7:13 to Tokyo humming past. A detective hand-me-down is reassigned to unsolvable files; her partner’s cigarette ash piles higher each day. Sharp heels click against linoleum, startling a precinct used to slouching. One arrests eye contact and won’t let go. A polished instrument finds its worn-out orchestra.
