Yoo Jinho

Gray eyes and a boyish face mark Jinho out, topped by custard-colored hair kept shaved on every side of his head. As with Jinwoo, casual clothing is his default, even on raids. The revised timeline finds him older, his face firmer and more masculine, his frame leaner, and a touch of stubble added; even so, the haircut never changes, and despite reaching his forties he has aged remarkably little, showing only a few faint creases by his mouth and the corners of his face.

Endearingly clueless, Jinho fills the role of the show's comic relief, forever taking things the wrong way. Beneath the goofiness, though, sits a young man who is fiercely loyal and ambitious: he once aimed to run the Yoojin Guild as its master and one day inherit the family business, and he proved willing to step away from his father to help Jinwoo, whom he looks up to like an older brother, build a guild of his own. Two recurring jokes follow him around. One is his habit of suiting up in gaudy, costly, and entirely useless armor; the other is his hopeless tolerance for alcohol, which left him completely plastered after drinking with both Jinwoo and his cousin Soohyun.

Jinho first met Jinwoo after signing on with the strike team led by Hwang Dongsuk, brought aboard only to round out a ten-man quota for a C-Rank dungeon. Watching the others write Jinwoo off as a useless E-Rank, he pledged to protect him, only to wind up leaning on the rookie for advice once they were inside. Deep in the cave maze they reached a chamber loaded with Mana Crystals near the boss's lair, and Jinho noticed that the contract left those crystals unaccounted for. Dongsuk smoothed the matter over with a smile, then sealed the two young hunters in with the waking boss, meaning to kill them both. To Jinho's amazement, Jinwoo fought the Giant Arachnid Buryura on even terms and felled it single-handed, leaving Jinho convinced his senior was a hidden False Ranker. When Dongsuk's crew returned, the older man offered to let Jinho live if he killed Jinwoo; Jinho refused, drew his blade against him, and looked on in horror as Jinwoo cut down the corrupt hunters before the pair fled the collapsing dungeon.

In the aftermath Jinho gave every salvaged crystal to Jinwoo and stayed quiet about the whole affair, then tracked him down to recruit him for a private attack force. Jinwoo turned him away at first, but Jinho kept at it, admitting he needed only a few more raids to earn a guild master license and start his own guild for the family company. Jinwoo finally agreed on the condition that only the two of them go inside, and they satisfied the legal headcount by hiring sidelined hunters to wait outside, paying them well to keep silent. The setup let Jinwoo hide his real rank while clearing C-Rank gates effortlessly, Jinho mining crystals while his partner slew the beasts. In the Ragnarok timeline, after the Great Cataclysm caused both Suho's parents to vanish, Jinho took the boy in and agreed to fund Woo Jinchul's new hunter organization, on the condition that it also work to find Suho's missing parents.
