Life seems pretty normal at the Forensics Division. Ippei's canine partner, Oliver, appears to him as a womanizing middle-aged drunk in a dog suit, but that's nothing new. However, when "Super Volunteer" Konishi vanishes, the investigation pulls them into a bizarre mystery. Joined by Supervisor Hagoromo, Ippei and Yukina follow Konishi's trail, Urushibara uncovers a family secret, and former handler Mizoguchi stumbles upon a takoyaki-infested town and a tiny fairy man. All while mysterious red doors keep appearing… Something is obviously deeply wrong. Can the team find Konishi and save him from unseen forces before chaos consumes them all?
