ID: Invaded Complete Series of 3 Volumes

In a futuristic world, investigators have the power to tap into a killer's subconscious and see fragmented parts of their psyche. It's called an "identity sink," a mental plane that can be digitally investigated to gather clues about victims, crime scenes or a killer's motives. We follow the investigations of Narihisago, a renowned detective now in prison, tasked with delving into the wells of identities of various serial killers. Two years before current events, Narihisago's daughter Muku was brutally murdered by a serial killer, leading Narihisago's wife to commit suicide. These deaths prompted him to track down and murder the killer, earning him his prison sentence. He is still depressed and haunted by the deaths of his wife and daughter, but also uses this as motivation to take his job seriously and help stop serial killers. However, following the death of his family, he resents all serial killers, which sometimes manifests as an uncontrollable urge to kill.
