Mayu Nozaki (野崎 真由 Nozaki Mayu) is the younger brother of Umetarou Nozaki. He is a third-year student in junior high.
Mayu has black eyes and black hair. He is physically fit due to being the captain of the judo club at school. His school uniform is a black gakuran and he wears it buttoned up. Additionally, he is occasionally seen wearing his judo uniform.
Mayu notable character trait is his laziness. He puts the minimum amount of effort necessary whenever possible, except for during judo after school.
Mayu is also a skilled artist and learnt drawing to make appealing diagrams of floor grappling techniques to interest the judo club members. He used Mikoshiba Mikoto's manga collection as a reference so that he could draw varying styles of attractive women.
He is very passionate about judo and sports, holding great respect for his seniors in sports clubs like Hirotaka Wakamatsu.
Mayu is highly skilled at judo and is also the captain of the judo club.
His love for judo is so great that it can drive him to accomplish almost anything else he sets his mind to. When he was told that he wouldn't be able to attend club unless he brought his grades up, he immediately raised them to perfection. He learnt to draw so that he could make the club members more interested in floor grappling techniques by drawing cute girls in the various positions and holds. His friend posts the art to a blog titled 'MayuMayu' and the art is fairly popular.
Umetarou Nozaki is Mayu's older brother. He is the only one that's able to understand Mayu's minimalist texts. He protected Mayu from bullies, which led to Mayu continuing to rely on others and be lazy. Mayu didn't want his brother to leave their home but he was too lazy to try and stop him. Mayu and Nozaki are close despite their physical distance but they understand each other well.
Mayu and Mikoshiba occasionally spend time together when he comes to his Nozaki's apartment. They're friendly with each other. Additionally, Mayu calls Mikoshiba by his first name but uses an honorific (Mikoto-san), implying that they are close.
However, they are also texting each other under pseudonyms, unaware of the other's identity. Mayu acts as a girl named 'MayuMayu,' using the blog his friend runs that features the art Mayu creates for the judo club. Mikoshiba is going as Mamiko because he feels that it would be creepy for a high school boy to text a middle school girl and that 'MayuMayu' would feel more comfortable talking to another girl.
