Jin-Ho Yu

Yoo Jin-Ho serves as vice guild master of the Ahjin Guild, the hunting organization led by his close friend Jin-U Seong. Though he started as only a modest fighter, Jin-Ho earns his place at Jin-Woo's side through unwavering loyalty rather than raw combat power, acting as his trusted partner on missions and in guild business alike.

Jin-Ho's personality leans toward dorky and a little childish, and he often ends up as the series' comic relief, cracking jokes or getting flustered at the wrong moments. That goofy surface hides real dedication, though: he sticks with Jin-Woo through dangerous jobs even when his own fighting skills lag far behind his friend's growing power, trusting him completely to keep them both safe.

As the Ahjin Guild grows under Jin-Woo's leadership, Jin-Ho takes on more responsibility managing the guild's day-to-day operations, handling tasks that keep things running smoothly while Jin-Woo focuses on fighting. Their friendship, which started when Jin-Woo was still considered one of the weakest hunters around, remains one of the few relationships in the story untouched by jealousy or fear of his incredible rise in power.
