Deep Red is written by Hisashi Nozawa.
Sixth grader Kanako was looking forward to her school trip, and she sure is enjoying it. At night, as she and her friends exchange scary stories after lights-out, her teacher barges into their room to summon her. Yet he seems more solicitous than scolding, and when he asks her to pack her things so he can take her back to Tokyo in a cab, Kanako realizes that something terrible has happened to her family.
Educational supplies salesman Norio Tsuzuki was bamboozled into co-signing a fraudulent loan agreement by a business relation of his to whom he couldn’t say no. Enticed by the unscrupulous entrepreneur to recover the sum by unethical means, Tsuzuki indeed descends into criminality—by brutally murdering the man and his family. The only survivor, a daughter the same age as Tsuzuki’s own, just happened to be away on a school trip…
When the orphaned Kanako grows up into a young woman, she cannot but feel vengeful toward Miho, the fiend’s daughter, and seeks her out under false pretenses. What follows is a memorable waltz of two unmoored souls.
