Date Kaname

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

Also the ultimate coomer.

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 Aiba (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.

Episode 9
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 in the middle of the season.

Episode 3
Date fills in for a match meant to determine the next member of the famous investigator ring of wrestlers The Mystery Masters. While Date didn't manage to win, he works best with just the little voice inside his head anyway.

AI: The Somnium Files
In November 2019, a body was found at Bloom Park with multiple stab wounds and a missing eye. Date was called in to investigate the crime scene. This would start his greatest case, meeting the internet Idol A-set who was targeted by assassins for revealing one of the secret missions of The Bogdanoffs.

Episode 9
Kaname Date has returned to the ring, perhaps because he has taken a liking to wrestling. However, some reports there's something strange about him, feeling his head a little bit more metallic than usual.

Episode 10
Perhaps because he investigated a little too much, Kojima decided to put him in the universe with the oncoming Final Impact, and in a match where his very life is at stake. After being defeated by a man with a terrifying stare, Date just laments he won't be able to see 2 particular girls one more last time...

Episode 11
However, TFI was averted, and since Date couldn't help, he vows to try harder if anything were to happen in TFR. Except if a rare porno mag is at stake...
