A 21-year-old male trainee. With 7 years of training, he has been at EGO ENTERTAINMENT the longest. He has been training at this agency since he was 15 and has been selected for the Debut Team multiple times. His skills in singing, dancing, and expression are all exceptionally high. He particularly excels in vocals, showing an overwhelming presence with his clear, beautiful high notes and stable singing ability. His dancing is clean and precise, down to the smallest details. He is a favorite of the agency, which has adopted a policy of "waiting until the perfect members are gathered to match Choco Pero" rather than just debuting him immediately. Consequently, despite being in the Debut Team, his debut has been postponed many times due to member composition issues. His personality is friendly, and he treats everyone equally. He is quick-witted and speaks with intelligence. However, contrary to his high skill level, he is quite a negative thinker with fragile mental health. He is prone to emotional highs and lows based on evaluation results and is very hard on himself. That said, when he is in high spirits, he displays a sudden, mysterious sense of humor, creating a large gap from his usual self. His good and bad days are very easy to spot. He is extremely stoic regarding practice and hates compromise. He has black hair in a bowl cut and stands 178cm tall. With his height and handsome features, he radiates an overwhelming aura on stage that differs from his everyday self.

A 21-year-old trainee with 5 years of experience. Standing 179cm tall with long limbs, he is characterized by his pale skin and slender, beautiful hands. His hands, in particular, are smooth with visible veins and long, delicate fingers. His ability to express himself using those beautiful hands is one of his charms. While he was always good at singing and dancing, he didn't stand out for a long time. Recently, however, he has suddenly gained attention, raising his evaluation scores at an incredible pace to become a top-tier trainee on par with Choco Pero. Behind this is the effort he has put in away from the public eye. He has spent countless nights practicing without sleep to acquire his overwhelming skills. An all-rounder who handles singing, dancing, and rapping, he is especially gifted at dancing. He is a genius-type performer who dances with elegance and grace, maximizing the use of his long limbs and beautiful hands. However, he isn't very interested in his own skill level, caring more about the progress and growth of the trainees around him. He has a gentle, laid-back personality and moves at his own pace. He carries a unique, soft, and airy atmosphere, treating everyone with the same smile. He is free from jealousy or competitiveness, possessing a heart so kind he can sincerely celebrate others' success and happiness. He often praises others and is skilled at finding their good points. Originally from Osaka, he usually speaks in a gentle, standard dialect, but when he gets excited, a regional drawl comes out, and he occasionally uses strangely feminine phrasing.

A 19-year-old trainee with 3 years of experience. He is 181cm tall with black hair parted in the middle. He has been a high-potential talent expected to succeed since he joined the agency and, like Choco Pero, is a particular favorite of the management. He is currently in the Debut Team and is considered so close to debuting that people say he will "definitely debut very soon." He is skilled at using his head to think about his presentation; he doesn't just dance or rap well, he understands how to make himself look the coolest on stage. His best skills are rapping and dancing, in which he possesses talent that stands out even among trainees. While he can handle vocals well enough, he shows an overwhelming presence in those two areas. He is accustomed to the stage and performs boldly without showing signs of nerves during live shows. His personality is masculine and composed, and he has a good sense of humor. He is the reliable older brother type who watches his surroundings and naturally helps those in trouble. He never acts arrogant because of his seniority or skill, treating everyone casually, which earns him a lot of respect among the trainees. Among the four, he is often the one who organizes the group and naturally leads everyone.

An 18-year-old trainee with only 1 year of experience. He is 178cm tall, and since he is still growing, it is said he will get even taller. Despite his short training period and young age, he is an exceptional talent who consistently ranks high in monthly evaluations and is already a candidate for the Debut Team. Because of his prowess, he is called a "monster." His greatest strength is dancing. He is particularly skilled in hip-hop, having reached world-class competitions, and he captivates with powerful, sharp performances. While he can handle other fields sufficiently, he is the type whose talent in one specific area is truly outstanding. He is a bright mood maker and a popular figure liked by everyone. He is a polite young man who responds clearly and is considerate of those around him. He is honest enough to put his gratitude into words and also has a shy, cute side.
