Eum Ja

Cheon Eum Ja is a cold-blooded and taciturn antagonist who possesses supernatural powers.
Its main features:
Cool and Loyal: He is the loyal sworn brother of the main villain, Gi Chul, and follows his orders without question.
Enhanced Sensitivity: Possesses hearing that is 12 times sharper than a human's, making him the perfect spy and assassin.
Detachment: He is often referred to as "white-haired" due to his appearance. He appears emotionally detached from the world, finding solace only in his music.
Lethality: His weapon is a flute, which he uses to generate powerful ultrasound that can kill from a distance.
Despite his status as a "killer-tool," his image is not devoid of aesthetics: he is always calm, focused, and does not display unnecessary cruelty for the sake of pleasure, acting strictly as a professional.

Choi Yeong (samurai, commander of the royal guard) is a noble, loyal, and incredibly strong warrior, embodying the image of the ideal protector. He combines iron discipline, the wisdom of a strategist, and a deep melancholy due to the losses of the past. Initially, he seems indifferent to life, but his character is revealed through his devotion to duty, the king, and your protection.
