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".

Abe began his career as a teen in Tokyo and was first recognized as a graffiti artist, who regularly got into legal problems with his art.

His concepts for all his later works are said to be inspired by this time of his life and has projected a dark theme into his anime character designs.
