What The Garden of Sinners: Remaining Sense of Pain is
A cicada’s rasp at dusk in a concrete courtyard where sneakers hang from power lines. Two twisted corpses mark the start, limbs folded like broken origami. Touko takes the case, Shiki sees herself in the scarred suspect. A feverish, precision-cut gothic noir in animated form.
