If it was any other Saintess, I would not have risked my life to save her. Even if Saintess were important, would it be more important than my own life? For me, it is a no!
At most, I would have warned The Authority or the church about the attack. No matter how important that character was, if I don't have power or time, why would I save them?
I was far from being a hero who would save everyone that needed help. It was difficult to even protect one's life, not to mention others.
However, it was Saintess Amelia, someone who had saved my life at the cost of her life span.
At the time when I was dying due to using Dark Energy, she saved me using one of the forbidden skills exclusive to only Saintess. I know for a fact that those forbidden reduce lifespan and are used only in extremely rare cases.
Even though we don't share the best of relations. Still, it was a fact that I owed my life to Saintess Amelia.
