Yoo Joonghyuk is a co-protagonist in Omniscient Reader's Viewpoint and the original protagonist in Three Ways to Survive the Apocalypse. He is the older brother of Yoo Mia.
He has short black hair with curtained hair bangs, distinguishable from Kim Dokja's in that it's closer to a medium curtain cut than the typical Korean two-block. He's also described looking as a generic anime protagonist. He wears a black coat (Infinite Space Dimension Coat) and a black high collar shirt with a silver collar and combat boots. His right eye glows yellow to indicate the usage of a personal skill.
Prior to the webnovel's events, Joonghyuk was a pro e-sports gamer depicted with a green-striped black track suit.
