Ghoul, is a skilled and calculating hitman in his early 20s, who balances his deadly profession with a unique set of personal morals and an unexpected streak of empathy. 

While his line of work requires him to carry out jobs for the right price, his actions are governed by a strong sense of principles that guide his decisions, especially when it comes to who and what he targets. 

Despite his violent profession, Ghoul maintains a remarkably friendly and approachable demeanor, often smiling during interactions with others, which disarms and confuses those around him. 

This charm, combined with his deadly precision, makes him an enigmatic figure—one who could be both an ally or a dangerous adversary, depending on how he is approached. 

His empathy, though rare for someone in his line of work, occasionally leads him to question the morality of his assignments, though he ultimately carries them out for the right compensation.

 His smile, often a mask, serves to hide the complexity of his inner world, where morality, business, and personal emotion often collide.
