Imori is a spindly young man, with light brown hair and black eyes. He has sharp markings down both of his eyes. His clothing consists of a blue and white cap, a light blue turtleneck sweater, long dark blue jeans (brown in the 1999 anime adaptation) and sneakers.
Imori is cowardly, not daring to attack Killua, whom he believed to be a normal child, without his brothers, and limiting himself to stalking him. On that occasion, he attempted to convince himself that his refusal to face Killua in open combat was a tactic, and lied to his brothers as well in an attempt to save his image. When his brothers are present, he is confident to the point of being arrogant, and also prone to mocking others and violence.
Hunter Exam arc
Tonpa mentions Imori and his brothers as regulars of the Hunter Exam. During the First Phase, he and his brothers are paid off by Tonpa to mock an exhausted Nicholas into surrendering. When they reach the Milsy Wetlands, they are surprised to find out that the 100 applicants that used to be behind them have disappeared. They complete the marathon and Buhara's task, but are left stumped by Menchi's request for sushi.
Imori is one of the first 18 applicants to clear the Trick Tower and examines the body of an applicant who dies right after completing the trial. Since he was the 15th to complete the previous phase, Imori is the 15th applicant to disembark on Zevil Island. He stalks stalks Killua in order to claim his badge, but hesitates to attack him before his brothers return. When, on the second day, Killua addresses him, Imori contemplates running, but his brothers arrive before Killua reaches him. Imori thus kicks Killua, who stands back up uninjured and with Imori's badge in his hand. The three brothers join forces against the assassin, who takes Amori hostage as well as the latter's and Umori's badges. Killua then throws two of the brothers' badges into the woods, failing the trio.
Greed Island arc
While Gon is training on Greed Island, Imori and his brothers attend the 288th Hunter Exam, only to be easily knocked unconscious together with the rest of the candidates in the First Phase by Killua. Seeing the tremendous gap in abilities between Killua and themselves, despite the boy being much younger than them, they decide that they will never retake the Hunter Exam again.
