The Slayer Gerda grows in strength far faster than predicted. She is greater than any of us, having fused with both a body and mask given to her by The Snow Queen. Her appetite is voracious, and we simply cannot consume Demon flesh in the same quantities that she can. Saint Iota lags the furthest behind in this regard, because of her condition.

She is a perfect blade, ever more refined. She wields herself with no regard to safety or the future. I do not think she has any thoughts of tomorrow. 

I know that this is not good, but I am not able to judge such things. For the Saints therapy had no effect, but I do recommend seeing if Gerda could benefit. 

She occasionally touches my hand and does seem to want to spend time alone with me.

Before, I could have wanted nothing more.
