You can slightly hate Cynthia now too.

Also, Cynthia's Technique Formula is kinda like a Monkey's Paw wish. If someone caught inside is smart enough to find a loophole in her wording, the barrier accepts the requirement as complete.

For instance, if Sable is smart enough, he can agree not to attack ONLY members of Vyper Bolt OR members of Harpy's Wing. He doesn't have to agree to both.
