Baby

Not much is known about Baby Saja’s past before he became a demon. Unlike Jinu, Baby Saja never speaks of a former life, and the others suspect he was turned into a demon at a very young age. Some believe he was a child prodigy who made a pact with Gwi-Ma in exchange for fame and eternal youth, though this is purely speculation. Whether this was to escape suffering or to chase glory remains unclear.

On stage, he acts as an adorable and playful baby. He enjoys spicy food and lollipops for his fake persona. Behind the mask, he is a demon strategist, using his powers for most of his actions. He uses his cute face to devour people’s souls. Unless he's interacting with fans, he puts on a bored, uninterested mask and has a nonchalant façade. Nevertheless, he shows genuine shock when Jinu sacrifices himself for Rumi. After this, he is not seen again.

Appearance: Baby Saja has fluffy, short turquoise hair and turquoise eyes. He wears a collared blue shirt and a hot pink argyle-styled sweater with different shades of pink highlights on it. He dons a yellow, mustard-colored beret.

In his demon form, Baby Saja has glowing golden eyes with slit pupils, claws and fangs, sharp features, and pale blue-tinted skin marked by dark, vein-like patterns that glow faintly under neon light. His short hair remains a cool-toned blue-gray, but appears sleeker and more stylized. He wears traditional Korean clothing for the grim reaper/Chinese Hopping vampire/zombie such as a large, wide-brimmed black hat and dark clothing adorned with elegant beads and chains. His seductive expression give him an eerie, otherworldly presence. This form radiates mystery and power, with a striking and intimidating aura.
