He carries a strange sloth doll on his back. Weight: 25kg. Likes Chocolate. Teddy bears. You. Dislikes Bad-tasting food. Bandits. Monsters.

He changed his name to Kim the Thief because of his kleptomania. Since his true nature is kind, he could become an ally if treated well. His weapons are dual daggers. He wears a leather cloak, black gloves, and a scarf. He wears blue goggles that glow. Weight: Don't ask. Dislikes Monsters. Wasting food. Likes
