Go-Jaraji-Da

Go-Jaraji-Da (ゴ･ジャラジ･ダ)/Unidentified Life Form #42 (未確認生命体第４２号): Armed with needles, Jaraji assumed the form of youth in black who enjoys human suffering and snaps his fingers when able to move at fast speeds. He supported Gamego in his game before his death. When his turn came, Jaraji started to target 90 people by shooting his quills into them, having them die of encephalitis in four days. While going after Kazuya Ikuta, killing the police, Jaraji is interrupted by Kuuga, taking offense to it and leaving Kuuga wounded with a warning to stay out of his game. However, because some of his victims committed suicide, Jaraji is forced to find replacements before the 12th day ends. But when he was about to kill Kazuya to finish the game, Kuuga attacks Jaraji in a berserk rage, assuming Rising Titan Form to brutally kill Jaraji.
