Kensuke Aida is Shinji Ikari's classmate and friend; their mutual friend is Toji Suzuhara. As with all of Shinji's classmates, Kensuke is an Eva pilot candidate who is kept with other potential Children for his own protection. In relation to this fact, Kensuke's mother is deceased. Not much else is said about Kensuke's family life, but his father is at least alive.
Kensuke is fascinated with military paraphernalia and warfare. He acts out elaborate war scenarios in the countryside by himself, as seen in Episode 04, and was tremendously excited to be taken aboard Over the Rainbow in Episode 08, spending most of his time there taking video of everything in sight with his camcorder, regardless of what was happening around him.
Most importantly, Kensuke wants to become an Evangelion pilot extremely badly, making him benignly jealous of Shinji (though this is also for living with the attractive Misato Katsuragi). This never seems to have affected their friendship, though Shinji is confused by Kensuke’s enthusiasm about piloting.
It seems that no experience with Children will make Kensuke change his mind. He witnessed Shinji crying in the Entry Plug after the battle with Shamshel, and knew that Toji ended up in the hospital after being selected as Evangelion Unit-03’s pilot, yet when he found out that Shinji Ikari was leaving again after the incident, Kensuke’s phone message to Shinji, just before it was cut off, only said, "Damn! Even Toji became an Eva pilot, while I--" (Episode 19).
Kensuke often knows more about the doings of Nerv than Shinji does, and has hacked into his father’s data files to get such information on at least one occasion (Episode 06). Like the rest of the residents of Tokyo-3, Kensuke had to leave the area after the city was destroyed by the detonation of Eva 00 in Episode 23.
In the Proposal, Kensuke is depicted without his usual glasses and gives more of an impression of toughness, as opposed to the rather gentle and nerdy character shown in the Anime.
In Rebuild of Evangelion
In Rebuild of Evangelion, Kensuke closely follows his original role. In Evangelion 1.0, he and Toji witness the Shamshel battle and soon become close friends with Shinji. Kensuke demonstrates extensive knowledge of Nerv's internal projects in Evangelion 2.0, talking about the Eva-04 accident and Eva-03's imminent arrival. He is last seen with Toji, Hikari and Pen-Pen, holding his video camera and cowering from missile explosions as Zeruel attacks Tokyo-3. His fate at the end of 2.0 is unknown, and there is no mention of him at all in Evangelion 3.0.
Evangelion: 3.0 + 1.0 Thrice Upon a Time (SPOILERS)
This article or section contains spoiler information from Evangelion media that has been recently released and/or is of limited distribution. Do not read any further if you do not want to spoil your experience of said media.
Kensuke proves a supportive figure for Shinji, not unlike Kaji, telling him about how he overcame his difficulties in life and became a part of the community. He is receptive to Shinji's situation with his father, and tells him of Kaji's death and his son, named after him. When the Wunder arrives to pick-up Asuka, Kensuke and the others insist on Shinji not going with her, but he insists. Later, in a flashback to Shikinami's childhood during Instrumentality, she laments not having a parent to care for her, and Kensuke tells her it is alright.
Kensuke returns in Evangelion: 3.0+1.0 as an adult, working as a self-described "jack-of-all-trades" in the survivor's village. He is very friendly to Shinji and has an as-yet-undetermined relationship with Asuka  and she lives in his house when not in the AAA Wunder where she instead shares quarters with Mari. Asuka remains isolated from the community, as she wishes to avoid "the Lilim", calling him by the nickname "Ken-Ken", though he still refers to her only as "Shikinami". Toji mentions how helpful Kensuke, the "survival otaku" has been in keeping their community together. Visually, Kensuke looks very similar to Ryoji Kaji, the elder. After Kensuke leaves on a supply run, Asuka strolls around naked in his house and finds Shinji, who much to her irritation, reacts badly to her DSS Choker, still traumatized by Kaworu's death. Kensuke appears, covers Asuka, and cleans Shinji's vomit. They talk and Asuka expresses irritation at Shinji's inaction, but Kensuke defends him. Later, Kensuke finds out Shinji ran away, but before leaving to retrieve him, thanks her for feeding Shinji, to which Asuka responds: "It's not like I did it for him or anything".
In Other Media
Shinji Ikari Raising Project (Manga)
In the SIRP Manga, Kensuke's role is that of comic relief, much like most of his appearances in the original series. He is also presented as a conspiracy theorist, with "crazy ideas" about a secret society known as SEELE, NERV's goals, Human Instrumentality, etc. He remains friends with Tohji and (after a fashion) Hikari.
- The name "Kensuke Aida" was taken from Ryu Murakami’s novel Ai to Gensou no Fascism (The Fascism of Love and Fantasy)
- In Episode 03 Misato brings up Kensuke's I.D. info on her computer:
- Kensuke Aida is originally from Yokohama (which is just southwest of Old Tokyo), he was born on September 12th, 2001, and his blood type is A+.

"No, this is... Lilith!? I see. I understand the Lilin now."
- Yuko Miyamura apparently believes that Kensuke is in more of a father figure than a lover to Asuka, based on the ongoing interview translations.
Let’s talk about Ken Ken. First, when I received the script, I noticed Kensuke was written into it. Even though he wasn’t called Ken Ken, there wasn’t that kind of connection in the previous film, Q. In the TV series, he was one of the “three idiots.”<brAsuka will give people nicknames like “baka Shinji” and the like.
Asuka’s not a human and can’t live with the people in the third village so she freeloads off of Kensuke.
Asuka was isolated, she couldn’t grow up, only her hair grew.
Ken Ken is trying to take care of an isolated Asuka.
Ken Ken took the place of Mr. Kaji.
Try to think about this everyone. Ken Ken is such a good guy. Do you think such a good guy would try to advance a physical relation with a troubled 14-year-old girl?
Asuka says to Shinji that she's already become an adult but that doesn't mean sexually.
Asuka says “I am alone (in the film)”. Asuka was isolated.
Ken Ken has been watching over Asuka.
I think Ken Ken is like a father [to Asuka].
Asuka and Kensuke’s relationship is not a romantic one but rather a parental one.
When Shinji said “I think I liked Asuka,” it means that at the time he liked Asuka, even though he never came back 14 years ago.
To be honest, at the time of recording the last scene, Director Anno and Assistant Director Tsurumaki explained it.
Director Anno told me that Asuka’s ending scene correlates to the idea that Ken Ken is like a father to child Asuka.
Asuka really wants the father and mother that she's never had and Kenken could see this so his intention was to foster something like that.
Personally, I really think that “Ken Ken’s not a bastard.”
I'm not a fan of the "Ken Ken" scene.
I personally strongly think "no way Ken Ken is acceptable [as Asuka's partner]"
I think the Original Asuka is not Asuka Soryu.
My performance instructions were “Please do Soryu and Shikinami differently”
Asuka Soryu was not a clone.
When adult Asuka says, “Baka Shinji,” it has a special meaning.
Ken Ken doesn’t make a move on Asuka.
Ken Ken would never make a move on 14-year-old Asuka.
Ken Ken whose affection is deeper than the sea, stands by Asuka's side without laying a finger on her. [Imitating Asuka's voice].
Miyamura confirms Tsurumaki was in charge of everything Asuka-related, and asks fans to create new fanworks on pixiv for her to see.
Yuko Miyamura, MIYAMURA YUKO Corp. - Fanicon March 20th 2021, around 37 minute mark.
- Shinji's still fourteen both inside and out, and I don't think he could have helped Asuka, a girl fourteen on the outside but twenty-eight on the inside. Kensuke's twenty-eight on the outside and on the inside, so wouldn't he be the person who could do it? In the group for all the EVA voice actors on the LINE messaging app, Miyamura Yuko posted, "If Kensuke's the one who can be there for her, then please be there her." - Tetsuya Iwanaga (Kensuke), 3.0+1.0 booklet interview
