Haseo was created by CyberConnect2 CEO Hiroshi Matsuyama whose aim was for him to be a different protagonist from the previous ".hack" lead Kite. Since Kite was created to be the player's avatar in the original story, Haseo was meant to be more individual when it came to his characterization, by giving him darker traits. He was designed by Seiichiro Hosokawa, a new artist who joined CyberConnect2 in 2006. Takahiro Sakurai voices Haseo in Japanese. In the English version, he is voiced by Yuri Lowenthal in the games and Andrew Francis in the anime.
