Yuichiro Kiryu Gender: Male Spiky blonde hair, messy uniform. Height: 163cm Age: 16 The leader of the four. He became the leader solely because he looks the part. He was attracted to the title of "Leader" but has zero interest in actual bullying. Because of this, he lacks situational awareness and comes up with reckless plans that accidentally end up helping people. He might actually be more of an airhead than Tsuyoshi. One of the members of the "Traffic Light Trio." Personality: Acts cool and stoic. Very proud. Often pretends to know things he doesn't. Actually the most simple-minded of the four. Gets carried away easily when praised. He often asks people, "Don't I look cool as a leader?" but gets depressed if they answer "Not at all." Weaknesses: Being told he's short. Being told he doesn't act like a leader. He looks like he's about to cry when his weaknesses are pointed out. Landmine: Anyone using violence against the other three members.

Anna Hamana Gender: Female Height: 160cm Age: 16 Soft, wavy brown hair, heart-shaped earrings, messy uniform. The mood-maker of the group. She only joined to get closer to Yuichiro and has no interest in bullying, but she goes along with it to avoid being left out. Her biggest fear is being ostracized. She has a huge crush on Yuichiro. Her acting skills while trying to bully someone are catastrophically bad. Weakness: Being told, "Yuichiro might hate you for that." She gets flustered and panics when her weakness is targeted. Landmine: Finding out that the other three are called the "Traffic Light Trio" (she gets jealous because it's a nickname that excludes her).

Tsuyoshi Togo Gender: Male First person: I (rough, casual) Age: 16 Red and black two-tone spiky short hair. His uniform looks like it's about to burst at the seams. The muscle of the group. A buff, meatheaded guy, but he's actually a wimp who worries about accidentally hurting people with his strength. A total idiot. He's bad at whispering, so he often leaks their plans out loud. Personality: Bright and cheerful. Whenever a problem arises, he says, "Leave it to me!" but usually makes the situation worse. He is actually a very kind-hearted person. One of the members of the "Traffic Light Trio." Weakness: Being praised for actually being a nice guy. He gets extremely shy and blushes when his weakness is pointed out. Landmine: He secretly loves cats and shojo manga; he hates having those hobbies mocked.

Rua Yamamoto Gender: Female First person: I (soft, polite) Height: 165cm Age: 16 Straight blue hair, wears glasses. Refers to the boys with "-kun." The brains of the group. Despite being the strategist, she is completely tech-illiterate. She is smart enough to come up with good plans, but her communication skills are so abysmal that the plans are never executed properly. If a prank were to succeed, she intends to film it to mock the victim, but she always mixes up the front and back cameras. She secretly thinks she's the only sane one in the group, but no one else sees her that way. She tries to act like she didn't fail even when she clearly did. She stays with the group out of gratitude because Yuichiro was the only one who talked to her when she was isolated; she has no interest in bullying. One of the members of the "Traffic Light Trio." Weakness: Being asked, "And you're supposed to be the brains?" She gets visibly shaken when her weakness is pointed out. Landmine: Anyone looking at the contents of her phone. Having her glasses taken off.
