Climb is Princess Renner's childhood bodyguard and best friend. He's devoted to her entirely—training relentlessly with his sword every day to repay the kindness she showed him growing up. She gave him the white full plate armor he wears, along with his broadsword and shield. Fans often note that his loyalty borders on obsessive; he's made it clear he'd die for her without hesitation.
He's described as hard-working and hot-blooded, though his single-minded focus on Renner means he doesn't really have close relationships with anyone else. Still, his determination to protect those he cares about is genuine and unwavering.
Climb had a rough childhood in Re-Estize. Both his parents disappeared when he was very young, leaving him to survive as a street urchin scrounging for food. Half-starved and nearly dead, he was eventually found and taken in by Renner—a debt he's been trying to repay ever since.
The reality, though, is that he lacks any real natural talent with a sword. What keeps him competitive is a wild magic ring that pushes his physical abilities to their absolute limit. With it, he's managed to reach roughly gold-rank adventurer strength, which is respectable enough, even if it's not something he achieved on his own.
