Date Kaname

A detective that confronts looking for a murderer inside people's' minds, and the main character of AI: The Somnium Files.

Diver of the Dreamworld
Kaname Date is a "cold" and "calculating" Detective who has amnesia and remembers nothing before six years ago. He forms part of the Advanced Brain Investigation Squad, appointed by his Boss. Prior to 2013, he lost his eye in an accident that also caused him Amnesia, and got it replaced with a mechanical one a year later by Pewter of ABIS. This mechanical eye contains an AI-Ball (Or Aiba), a snarky AI connected to Date's brain that makes fun on him for his utter pervertness. This AI can "dive" into the Dream World (or "Somnium") of people, where she acts as his avatar to gather information from a subject's subconscious for his investigations in the waking world.

Date's most notable characteristic is being perhaps the most perverted man in the world, Kaname Date has every fetish known to man, and more. Aiba has reported no less than 136 fetishes in his brain, without going into sub-classifications.

Season 3
Date's investigations have lead him to the famous TFR Wrestling, where he theorizes a culprit must be hiding. First besting some guy who likes snails, his lead was proven wrong, but nevertheless he still believes the culprit must be close at hand in the wrestling scene.

Season 4
An important case has made Date leave the ring temporarily.

AI: The Somnium Files

Episode 9
