Guy A and Guy B

Two unnamed boys, dubbed "Guy A" (男A) and "Guy B" (と男B), are background characters of the Don't Toy With Me, Miss Nagatoro manga series. They are schoolmates of the protagonist and often tried to hit on Nagatoro and her clique.

Except for one occasion, they have been always seen together.

Appearance
Both the boys are quite muscular, robust build and attractive second year high schoolers, each at least a couple of inches taller than Senpai. On their firs appearance A has a bowl cut and B had spiky hairs, however from their second appearance they swap hairstyles. Their eyes, like those of many other characters, are never shown.

They typically wear their school uniform consisting of white button up shirts (with one flap always out of her skirt and collar never buttoned) and black trousers completed with sneakers. However, Guy A was also shown sporting jeans and v-neck fitted shirt while not at school.

Personalities
Both boys are very disrespectful, harsh, mean and lazy, regularly skipping their club practice, or committing delinquent acts. They also are pretty flirtatious, and Senpai was very jealous of their ability to approach girls smoothly, despite Nagatoro and her friends have described them as "boring", "annoying", "stupid, cocky and full of themselves", showing that they actually enjoy Senpai's company while rather avoid the duo's. Despite Senpai once imagined Nagatoro's clique acting just like the two boys do, once the girls guessed his tought, they scolded him for being rude as they have proved more than once to be nothing like them.

On his first appearance, A confessed to Nagatoro to be very unexperienced with girls and never even having fondled a girl's breasts, however it was implied to be a lie he told in order to have her lower her guard, since he was later seen having a girlfriend, suggesting he was cheating on the latter.

Early lives
Both boys were born in, and made friends to each others in the all-boys middle school they attended together, then they both enrolled Kazehaya High School and were placed in the section A, the class in front of Senpai's. They both joined the same club but it's unclear which one it is, also the one with lighter hair (B) formed a band making a genre of music that he described as derived from a "soul and hip hop artistic style" and "something that transcend art".

Introduction
At some point during their second year they asked Yoshi on a date and the latter, out of naivety, tried to act as a matchmaker inviting Nagatoro too without informin her about the intention to setting her up with one of them. The date went awry, however, due to Yoshi being more interest in taking drink and snacks, while Nagatoro finding both of them "boring".

New semester
The first day of the new semester, they approached Nagatoro, Yoshi, Sakura and Gamo-chan - to which they actually barely speak - starting to hit on them. When Senpai, who was looking at them from a distance too embarrassed to come any closer, stepped out of his hideout, Gamo-chan greeted him amicably and asked him to sit with them, giving the boy enough confidence to propose Nagatoro to walk home with him. The girl accepted, being immediately joined by the others, thus leaving the two guys behind.

Date at the zoo
Few months later, while on a date at the zoo with his girlfriend, the darker haired one (A) met Senpai and immediately started to mock him for drawing at the zoo. Senpai endured everything in silence as always until they criticized Nagatoro's drawing, then he lost his temper and yelled them both not to dare make fun of other people's hard work. Right at that moment Nagatoro came back and scolded the two for criticizing her drawing and harassing Senpai, making them apologize out of fear and then leaving.

Few days later, Gamo-chan informed Senpai and the other girls that both boys have been suspended for having gotten caught drinking alcohol at the party after the Culture Festival.
