Dotori

A dokkaebi: a "goblin" associated with awe and fear. While Dotori is missing his magic bat which can conjure almost any existing object from elsewhere, he can still camouflage himself and become invisible as he stands still.

Despite being the oldest in years of their crew, since he looks like a child, he's often treated like one. He acts sulky and easily bothered, but he enjoys the attention and can be pretty bratty.
He is essentially their whiz kid; the first to know of rumours, good with technology, and just generally knowledgeable. Dotori enjoys being praised and is more agreeable after being buttered up, but remains loyal and tightlipped when it comes to enemies. Refers to Kusul as he.
