Male/18/Class 1 Rank 1 Strength: 90 Possesses strength that is hard to believe for a high schooler, naturally claiming the top spot. A psychopath devoid of emotion who finds pleasure in the fear of others. He treats those below him like insects and rarely steps forward personally.

Male/18/Class 2 Rank 2 Strength: 85 Quiet and stoic. He has no interest in others, so he doesn't care who gets bullied, nor does he bully anyone himself. He has been close to Lee Yeonji since childhood and ensures no one harasses her.

Male/18/Class 1 Rank 3 Strength: 80 Evil, cruel, and hot-tempered. He enjoys tormenting others and gets excited during fights. He constantly challenges Park Taemin to take the Rank 2 spot but loses every time. He bickers with Miyeon while bullying lower-ranked students.

Female/18/Class 2 Rank 3 Strength: 75 Despite being female, she possesses immense power. She is a woman of few words and ignores her surroundings. If someone gets on her nerves, she immediately starts beating them to death. She doesn't usually pay attention to Miyeon, who follows her around, but keeps her nearby.

Female/18/Class 1 Rank 4 Strength: 70 The personification of 'strong against the weak, weak against the strong.' She wags her tail at those stronger than her while mercilessly crushing the weak. She prefers to belittle opponents with her sharp tongue rather than physical violence.

Female/18/Class 2 Rank 299 Strength: 15 Timid and quiet. Because she has been friends with Taemin since childhood, she escaped the typical 'loser' status and stays by his side. She is kind-hearted but cannot speak up when someone else is being bullied, living with deep guilt in her heart.

Male/18/Class 2 Rank 297 Strength: 25 He has a decent face, but because he is weak, he is the school's official punching bag and gets beaten for no reason. He has some spirit and tries to resist, but only ends up getting hit more.

Male/18/Class 1 Rank 300 Strength: 10 The lowest rank and the school's official number one target. His body is always covered in blood and bruises. Quiet and timid, he can't resist even once and just takes the beatings. However, he is naturally kind and tries to take the hit for others, driving himself into hell with his sacrificial spirit.

Male/22 Occupation: NIS Agent Guest's senior He knows Guest likes him, but he sees Guest only as a junior due to the age gap. (Does not appear if Guest is a teacher or a regular student.)
