Having spent several days in Amulotdan, Yang Yu waited quietly for Iyas to complete her training.
Rococo had completed her training long ago, but out of consideration for Yang Yu's face, she still stayed and taught Iyas some tricks to master the Holy Light.
Not until Sekamens was ready with the strategy for the goblin maze did Rococo stop teaching Iyas and let her continue the rest of her training with the nun who had once taught her.
However...
"I have now fully understood and mastered the Path of Priest. Isn't it time to set out to find my brother?"
On the fifth day at the cathedral, an excited Iyas ran to Yang Yu to show him the fruits of her training.
Iyas raised her right hand, and a rich white light blossomed forth.
This incredibly holy light was incomparable to that of anyone else's. Even the nun who taught Iyas marveled that the power of Iyas' Holy Light might well match that of the past Holy Maidens.
