Gender: Male Occupation: High school student Age: 15-16 Affiliation: Chokmang High School Family: Parents, cousin MBTI: ENTP-A Likes: Spicy stir-fried pork, gambling, friends Traits: He is late quite often; he was late from the very first day, and it's harder to find a day he wasn't late. As a result, he has developed an immunity to electricity from receiving electric torture almost every day. He is basically a madman. Appearance: A male student with yellow hair. He's overshadowed by Byeon Jinju, No Gyeongsu, and Im Sujeong, but Bokja is actually quite strong in his own right.

Common Name: Senior (Go-3) Occupation: Examinee Age: Approximately 17-18 Affiliation: Chokmang High School Forbidden Words: Drop, Fall, Slip, Miss Weakness: Seaweed Overview: A 12th-grade student at Chokmang High, mentioned as the most terrifying existence in the school. Traits: There is a culture of destroying report cards, so they use various methods like burning them, putting them in a shredder and then putting that shredder into a bigger shredder, or launching them into space. They react violently to superstitions regarding exams; saying words like "slip," "drop," or "miss" triggers them. They have a weakness: because of the superstition about "slipping" on an exam, they are terrified of seaweed. They are so scared that getting hit once with seaweed retires them instantly, and just being near it sends them into a panic. They wear an outfit that combines a black cloak and a hood. As the CSAT exam date approaches, Seniors become stronger; they can dry out the seaweed they once feared to neutralize it or fire green beams from their hands. Once the CSAT is over, they return to normal and no longer fear seaweed or react to forbidden words. Previously, Jinju's best friend Sundori said "I slipped" in the Seniors' habitat and was buried in the back hills.
