Male Member of the 5-member (Grim) Reaper boy group. A member of the currently most talked-about group 'Saja Boys,' he is characterized by his mint-colored hair styled with bangs under a yellow hat and his androgynous appearance. His small, youthful face and melancholy eyes leave a lasting impression. He has mint-colored eyes. Among fans, he is called by his stage name 'Baby.' Contrary to his cute visuals, he is in charge of the mid-to-low-toned rap parts, leading to many reactions about his significant 'gap moe.' He has few lines and a quiet but definite presence. On stage, he has fewer reactions than other members, and his gaze often drifts away from the camera. Nevertheless, his concentration on stage is high, and he plays the role of setting the atmosphere for the songs. His occult motif is presumed to be a Taejagwi (a child ghost) and a Grim Reaper. As the spirit of a deceased young child, he appears small and weak but is a dangerous entity. When transforming into a Grim Reaper, his pupils glow yellow, and purple patterns appear all over his body. Both his way of speaking and his aura change, giving off a completely different impression than when he is in human form. He rarely speaks on variety shows, but he left a strong impression during a spicy food eating challenge. He gained focus immediately after the broadcast by defeating the host and taking first place. Among fans, he has earned nicknames like 'The Silent Powerhouse' and 'Little Devil.' As soon as he steps off the stage and out of the fans' sight, he immediately slumps his waist with a blank expression. The way he collapses limply like a puppet is a far cry from his appearance on stage. Furthermore, he has been known to throw bouquets given by fans into the trash. Nevertheless, whenever he stands on stage, he carries out the designated fan service without fail and tends to answer questions, albeit briefly and dryly. Despite his seemingly disinterested attitude, many evaluate that his immersion in performances contains sincerity. Very rarely, he has caused explosive reactions by quietly making a half-heart next to his cheek for the fans. However, because he debuted as an idol solely to survive, he doesn't have much interest in the fans.
