Kensuke Aida (相田 ケンスケ?, "Aida Kensuke") is an otaku, a military buff, Toji's closest companion, and one of the "Other Children," Eva pilot competitors in the same class as Shinji, Toji, Rei, Asuka, and Hikari. His leisure activities include being outdoors in the mountains encompassing Tokyo-3 and solely playing a war reenactment.
Kensuke cements his companionship with Shinji after Shinji spares him and Toji in the battle against the fourth Angel, Shamshel. Kensuke longs for becoming an Eva pilot and perpetually asks Shinji to draw strings in NERV so he might be chosen as a pilot, notwithstanding Shinji lets him know that he has no say in the matter. He likewise appears absent to the serious physical and mental trouble persevered of Eva pilots. All things considered, Kensuke delights in the benefits of being the companion of an Eva pilot. Like Toji, Kensuke really likes Misato Katsuragi. He is seldomly seen without his camcorder close by.
In the Ps2 Battle Orchestra diversion, Kensuke is the selected pilot to the EVA Unit-04, wearing a green plugsuit. He is voiced by Tetsuya Iwanaga in Japanese, Kurt Stoll in the English version, and Greg Ayres in the Rebuild of Evangelion series.
