A famous cover and character designer. He owns a bearded dragon as a pet.

He received his Master of Fine Arts from the Tokyo National University of Fine Arts and Music.

His works have an edgy style due to, among other things, his not using a ruler while drawing as is usual for most anime-style art. He first gained fame in his work on the avant-garde anime Serial Experiments Lain. He is also responsible for the concept and character design for the series NieA under 7. He is the creator of the doujinshi Haibane Renmei which was then adapted into an anime.

He is a colleague and friend of Chiaki J. Konaka, with whom he collaborated on the series Serial Experiments Lain and Texhnolyze. He usually uses the Romaji form of his name instead of the kanji, with the "B" in "ABe" capitalized, as a reminder of his early works, for which he used the pen name "AB".
