Eiji Niizuma (新妻 えいじ, Niizuma Eiji) is a high school genius mangaka who has been drawing manga ever since he was little. From Aomori he moved to Tokyo for the serialization of his manga Yellow Hit with the condition that if he becomes the Jack's best mangaka he will be given the right to end one series in Jack that he hates. Niizuma also has a great love for manga, loving manga more than Ashirogi Muto and his opinions are valued by everyone at Jump. He also is able to give pretty spot-on analysis to other manga, as when he predicted the results in the Golden Future Cup. His rival is Ashirogi Muto, though he is also a fan of their manga.
