He has known Ken Miyamae since high school, and both of them went to the same college.
Maeno has amber eyes, short silver hair (depicted as dark brown in the anime) and a messy fringe which is parted in the middle. He wears a varied selection of outfits which are commonly paired with white trousers. Some of these include: a grey blazer over a blue shirt, a yellow cardigan and a blue collared vest.
Even though he seems to be an ordinary friendly guy, he is a narcissist, and according to Nozaki, he always claims his suggestions are great ideas. This personality also can be seen through his actions using Monthly Girls' Romance editor's blog as his personal blog.
He is an incompetent person, who is always giving very bad suggestions, for example, adding unnecessary characters like elephants. He is also careless in his actions, for example, he casually loses Yukari's manuscript, and spills curry on another one. However, he has cute side that he is fond to cute characters such as tanuki, though he frequently forces the artists to add tanukis to every panel, even at the expense of disrupting important moments in the manga.
It is implied that he is initially popular with the female mangaka that he works with due to his looks, but they gradually end up disliking him due to his personality.
Ken and Maeno are editors under the same publisher, Monthly Girls' Romance. They were student in the same highschool and had the same ring of friends. Maeno graduated and got into the industry two years earlier than Ken, making him a senpai. Although Ken hates him, Maeno genuinely believes they are friends and annoys him to no end.
Yukari is a manga author under Maeno's management. She receives unhelpful advice from him, such as adding tanukis, but complies anyway despite the complaints of others. Maeno persuades her easily due to her soft spoken disposition.
Umetarou Nozaki, pen name Yumino Sakiko, is a manga author that used to be under Maerno's management before bering transferred to Ken Miyamae. He cannot stand Maeno for his incompetence and is eternally grateful to Ken for replacing him.
