At this point I'm convinced that she won't be successfully executed by anyone. No matter what they try she may have a skill or skills that will let her bounce everything anyone throws at her right back at them. Stake burning, fire travels in the opposite direction. Guillotine, it somehow shoots straight up in the air and vanishes into the sky. Being hanged, the rope becomes undone and she walks away cheerfully. Yeah, nobody can capture her unless she lets them. Even as a captive, I doubt anyone can kill her unless she allows it. Unless she is unable to move, can't use her item box, and can't use her skills, she won't die so easily. Even then they would need to have equipment strong enough to bypass her level defenses.
