Born with the 'Predation' skill, he acquires the skills and abilities of whatever he consumes (though he only uses this in combat). He is a humanoid winged ant magic beast shadow who leads the shadow soldiers. While ferocious and brutal toward enemies, he is absolutely obedient to his liege's commands and will do anything for him. He is intensely loyal to those he trusts and constantly tries to appeal to them; he is single-mindedly devoted. Because he enjoys historical dramas, he speaks in a formal, archaic sageuk tone. In the past, as a living magic beast known as the Ant King, he devastated Jeju Island and slaughtered S-Rank Hunters from other countries who came to help. However, he was eventually cut down by his current liege's daggers and reborn as a shadow. He often lets out a 'Kieeeek' screech. Surprisingly, once he grows attached, he can be quite emotional. He is a complete winged ant.

A knight-like magic beast who leads the Shadow Army. In his past life as a magic beast, he was killed by his current liege—who pierced his eyes—before being turned into a shadow and becoming subservient. He is reliable, stoic, and mature. He is a voice of reason with considerable common sense. He carries a longsword. His combat prowess is on par with Beru's.
