Abby Saja

Appearance Abby is a tall man with a athletic physique, known for his defined abdominal muscles. He has an oval-shaped face with high cheekbones, a straight nose, small lips, and a prominent jawline. As a human, he has lightly tanned skin with rosy cheeks, short raspberry pink hair, brown eyes, and dark eyebrows shaped with a barbed point at the center. In demon form, he retains most of these features, with the exception of purple skin with patterns, clawed hands, sharp teeth, and glowing golden eyes.

While disguised as an idol, Abby typically wears beanies, button-up shirts, ripped skinny jeans, and and high-top sneakers. His nails are also manicured with designs that are black, pink, and yellow.

As a demon, Abby wears traditional Korean clothing, including a gat and a tattered black hanbok comprising of a long jeonbok vest, a jeogori top, baji trousers, a sejodae sash tied around the waist, and hye shoes.

During the performance of "Your Idol," Abby combines traditional and contemporary clothing, wearing a gat, a black sochangui overcoat decorated with demon patterns on the cuffs and hem, a pendant on the chest, two necklaces, a fishnet crop top, a strap across his chest, two chains on his left side, fingerless gloves, rings on both hands, shiny leather pants, and knee-high platform boots with multiple buckles.

Personality Abby is portrayed as the "eye candy" of the group, with a confident demeanor and strong performance abilities. He is also depicted as a tease, often showing off his physique to provoke reactions from others. This behavior occasionally borders on vanity; for example, during the HUNTR/X fansign, he distributed signed drawings of his abdominal muscles while admiring his work. Nevertheless, Abby has self-awareness, as shown in the bathhouse scene, saying he wasn’t surprised HUNTR/X followed them because of Mira and Zoey's attraction to him.

Like the other Saja Boys, Abby has shown signs of aggression, being among the first members to attack the hunters following Jinu's sacrifice. However, his effectiveness in combat is questionable. In a confrontation with Mira, he merely poses and flashes his abs, expecting to distract her. Ultimately, his failure to take real offensive action leads to his demise.
