The first arc was mainly about the Saint and her comrades. She was mentally stunted from all the abuse she received since her childhood. When she was stranded in the forest, she met an injured priest who was harmed by treacherous scheme of his fellow priest. The injured priest felt indebted to her and took the role as her guardian, along with his comrades.

The priest and his comrades, who thought themselves as her guardian, decided to pick the best method to protect the saint's heart; a cruel yet kind act, which the saint absolutely abhors. In the end they realized what they think the best path might not what the saint want, and they had, in their arrogance, unknowingly deeply hurted the saint.

Since then they decided to respect the saint decision, even though that decision might bring misery to her later.

The second arc is about invasion from other organization and how the saint finally accept that she, mentally, might not be a normal human being, and in her role as a saint, she willingly accepted her imperfection as something necessary to uphold the role given to her.
