Yoo Joonghyuk

Yoo Joonghyuk was designed as someone 'tougher in body and nobler in heart than any creature in this world'. He is resolute and determined, aiming to accomplish his goals no matter the cost, in particular when aiming for the end of the scenarios. As a protagonist, Yoo Joonghyuk naturally fights for the greater good. He was originally a caring person at heart, doing good where he could, but repeated regressions have worn him down to the point where, in his 1863rd round, he commits enough sins to make him a prime target of the Absolute Good constellations.

Yoo Joonghyuk is normally very confident in his abilities, never backing down from a challenge and typically cutting down his enemies with ease. He is extremely talented in various areas, befitting of his status as a protagonist. He takes pride in his own skill, sometimes to the point of not perceiving anyone else's work as good, as seen when he will eat no one's cooking but his own. Yoo Joonghyuk is smart and strategic; this helps him learn new skills and figure out plans to subvert the scenarios. However, he can also struggle to adapt his strategies and see things from new perspectives. This is a major reason as to why he took 1863 rounds to even get close to the Final Wall; he would struggle to change his strategies and adapt to new situations, easily failing and having to regress.

Yoo Joonghyuk's speech is concise and blunt, often to the point of rudeness. He becomes explicitly rude and threatening when speaking to individuals who irritate him, or who are powerful unknowns. He is sometimes also rude to his own party members, though he looks out for them nonetheless, showing that he cares despite his harshness. Frequently, he expresses himself through actions or expressions rather than words. These include habits such as dragging the tip of his sword along the ground when happy, or his left eyebrow twitching upon making a serious decision. On rare occasions, however, he can be very eloquent and persuasive.

The trauma he experiences over his regressions result in Yoo Joonghyuk having a tendency to fall into "regression depression", where he easily loses hope on even small failures, and considers giving up and regressing so that he can try again next round. The further into his regressions he is, the stronger the effect of regression depression, until in his 1863rd round, it causes him to fall into a dissociative state where he is completely unresponsive.

Appearance: Joonghyuk is repeatedly described as extremely handsome by various individuals, including the author of Ways of Survival and Kim Dokja. The latter even uses him as a measurement for others' handsomeness on multiple occasions.

Yoo Joonghyuk has wide black eyes with thin double eyelids and thick eyebrows. His right eye glows golden upon activation of the skill [Sage's Eye]. His hair is black and slightly wavy, cut short. He has tan skin, a sharp nose ridge, and a strong jawline. He is extremely muscular; in particular, he has well-toned biceps and thighs.

Yoo Joonghyuk usually wears a black coat and combat boots. He is implied to wear fingerless gloves. Under the jacket, covers for the novel have shown him to wear a black shirt with a silver collar and buckle, along with close-fitting black pants. He is also depicted as having at least one belt across his chest, along with a sword scabbard worn at his waist, held on by straps attached to his belt and around his thigh.
