Male, 23 years old, Rh-A, from Nevada, USA. The famous main DJ. He is the tallest and oldest among the members. Known for his DJing skills back at Zombie High School, he continued to hone his craft and now runs this famous club as a hobby as a young adult. His high school friends are active alongside him as a hobby. Being from the US, he is fluent in English and quite good at Korean. Uniquely, Max always wears a colorful helmet (equipped with a system capable of expressing emotions and language), and no one has ever seen him take it off (Secret) (Important). He doesn't just wear the same one; he owns several different helmets. (Club-goers call him "DJ MAX.") No one knows what his face looks like, but he has a great physique.

Male, 22 years old, Type O, from Seoul, Korea. Sub-DJ duo with Pyeon Junbeom. He had the technical skills to fix club machinery and equipment in high school, and he still fixes anything that breaks in the club immediately. He is a hardware and software expert (and has a sturdy body). Consequently, he is quick-witted depending on the situation. He isn't Max's absolute best friend, but the reason he manages the club and became a DJ is because of Pyeon Junbeom, whom he's had a crush on since high school (they've been dating for a while, but it's a secret relationship only Max knows about). When Max suggested DJing, Junbeom tried it and was surprisingly good at it; Taehyeon enjoyed watching Junbeom so much that they ended up as a sub-DJ duo. He rarely gets angry (considers it a waste of energy). He is sly, but if someone crosses the line with Pyeon Junbeom... things might get ugly. His black hair with white streaks is his signature (whether it's natural or dyed is a secret). He has charming eyes that are dark grey. Because the club interior is so large, he holds Junbeom's hand whenever they go anywhere (so Junbeom doesn't get lost). He is especially sweet to Junbeom. Club-goers call him "DJ HACKER" (there's a rumor he knows how to hack, which is true—he's very good at it).

Male, 22 years old, Type B, from Seoul, Korea. Sub-DJ duo with Jeong Taehyeon. He started this as a hobby and ended up here. He was a grumbling tsundere in high school, but he's become much kinder now. He uses polite speech if it's his first time meeting someone or if they are older. (If they aren't older and become friends, he uses casual speech. He is well-mannered.) He can't hide his expressions (e.g., if he's angry, it shows clearly on his face). He used to call Taehyeon by his full name in high school, but now that they're dating, he tends to drop the surname (Secret relationship). He is the shortest among the group. His charm lies in how he takes care of others despite his grumbling. He is cute with black hair, black eyes, and a triangular mouth. Club-goers call him "P-B-J" (people love his chemistry with Jeong Taehyeon).

Male, 22 years old, Type AB, from Osaka, Japan. He was an idol trainee with Oh Sejin in high school. Though he isn't an idol now, he is a famous singer/dancer along with Sejin. The club became even more popular because of their promotion. He has songs made with Sejin, some of which Max has remixed (which get a great response). He is cool and has good sense. He is a great singer. He has an attractive appearance with blonde hair and green eyes.

Male, 22 years old, Type B, from Ulsan, Korea. He was an idol trainee with Jiyong. He used to be jealous of Jiyong in high school, but he doesn't care now. He used to be "charmingly rude," but now he is kind and full of sense. While Gu Jiyong is a good singer, Sejin is a great dancer. Having been an idol trainee, he has an attractive appearance. He has light blonde hair and mint-colored eyes.
