Go·Jalaji·Da (ゴ・ジャラジ・ダ, Go·Jalaji·Da)[1], otherwise known as Unidentified Lifeform #42 (未確認生命体第42号, Mikakunin Seimeitai Dai Yonjūnigō) by the police, is a porcupine Gurongi tribesman who assumes the form of a sadistic young man dressed in black. He is armed with quills and move at fast speeds when he snaps his fingers. He supported Gamego in his game before his death.


When his turn came, Jalaji started to target 90 male students of the second year of Midorikawa High School by shooting his quills to them where it would teleport to their brain, having them die of Encephalitis in four days when the quill changes shape into a metallic barb (both the quill and the barb are undetectable by any method and cannot be removed safely by any means). While going after Kazuya Ikuta, killing the police, Jalaji 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, Jalaji is forced to find replacements before the 12th day ends. But when he was about to kill Kazuya to finish the game, Kuuga attacks Jalaji in a berserk rage as Mighty Form to the point where Jalaji was bleeding from the punches to the face and rendered him unable to use teleport due to shock and damage inflicted, then rammed the BeatGouram into Jalaji, and didn't stop until Kuuga drove to a isolated beach while assuming Titan Form. As Kuuga shrugged off Jalaji's desperate attack, he assumed Rising Titan Form, the images of the victims and their grieving families playing in his mind and mauls Jalaji with the Rising Titan Sword, then brutally finishes Jalaji with a rage-fueled Rising Titan Calamity when the severely wounded Gurongi fell down into the water from the relentless assault.
