Kim Hyunsung

Appearance
The novel doesn't say much of character design but Lee Kiyoung said that different from himself Kim Hyunsung is what people would call someone handsome.

Personality
At first, he thought of everyone as useful or not, and dangerous or not, but after the Tutorial he felt a sense of true friendship with his companions.

Lee Kiyoung said that he doesn't know much of socialising and doesn't know how to make jokes.

He always tries to act for the party well being except when it is something personal.

 * [Overview: Truly amazing. If you don’t agree with me even after seeing it with your own eyes, I have no words for you. This person’s strength, agility and stamina can’t be accurately measured. His other stats also have incredible potential. His potential for growth as a wizard is terrifying, but with a melee class he can achieve even greater heights. He already has a common grade class and new opportunities for growth are on the horizon. Compared to player Lee Kiyoung… No, this comparison itself would be blasphemous. Player Lee Kiyoung should feel honoured to even be able to exchange a few words with this person.]
