 * Deconstructed: Himiko is under unbelievable pressure from keeping the world together by herself.
 * Reconstructed: It's obvious that no single person can hold the world together forever, so the law of the realm is amended to make the role of Barrier Maiden rotates amongst the most spiritually powerful priestesses of the world.
 * Zig Zagged: Himiko is raised to maintain the wall keeping the demons away, but then Bob and his band wipe out the demons so she doesn't have to, but this upsets the Balance of Good and Evil and the other world group that used to be humanity's ally turns against thm so Himiko has to make a wall against them.

 * Played for Drama: Mio, Himiko's lady-in-waiting can't bear to see her beloved lady shoulder the responsibility of the world alone. That's unfair, so she elopes with her. Thus it becomes a melee-a-trois: Mio, who want to protect Himiko from the pain of being a Barrier Maiden; Bob, who want to restore Himiko to her supposed role; and Centurios, who want to assassinate Himiko so he can start his demonic invasion. Meanwhile, being outside the Temple of All-Gods allow Himiko to see how rotten humans can be, and darkness grow in her heart... she's torn between keep on running from her responsibility, returning to her role, or take the mantle of Apocalypse Maiden altogether.
