Min-Gu Park

The father of Park Jeong-U. While his first appearance is a typical blunt father, as the story progresses he is displayed as someone who shows affection towards Jeong-U, who is losing his sense of humanity.

His life was full of lies and false testimonies. Since he was little, he pretended that his family was rich, that he was good at fighting, and even became a scammer when he became an adult. He constantly tried to make money by luring in possible investors for his startup companies but instead ended up with a large sum of debt.

His pattern of attacking is through expelling his essence through a thin strip of string. However because this is a method of expelling his essence through essentially a wave, his loss is extreme compared to other types of essence releases when he misses his targets.
