Kioku Sousa ~Shinjuku Higashi-sho Jiken Fairu~

Three years after turning himself in for his mother's murder, a man still refuses to reveal where her body is hidden. Based on Onizuka's deductions, the team canvasses Shinjuku and uncovers a dysfunctional family dynamic involving pension fraud and severe caregiver burnout. To crack the suspect's stubborn silence, Onizuka connects the case to an unusual mass death of civets that occurred in the neighborhood three years ago.
