Charlotte's Automaton
This is Charlotte's dragon-shaped automaton—basically a mechanical dragon she controls. It's actually a banned doll, which adds to its mystique and makes it pretty significant in the story.
The automaton relies on Luster Beam as its main attack, which Sigmund uses to take down enemies. It's a powerful move that seems to be the go-to offensive technique when things get serious.
