貞本義行
".hack" was conceived by CyberConnect2 with the idea of creating a fictional MMORPG in order to simulate a realistic story. The initial characters were designed by Yoshiyuki Sadamoto while later instalments involved additional artists. Critical reception to the original characters has been positive for their designs and realistic traits. The "G.U." characters received mixed responses due to Haseo's antiheroic characterization but praise for his growth.
