While trying to battles the haze in her mind, Azusa started to use various different skills of hers which looked to be useful in a situation like this. She tried various skills like "Steel Will", "Serene Mind" and such. But probably because they were all low level skills, the effect was not very useful.
After trying out several skills, one of them stood out very much. That skill was "Heart of Valor". As soon as she activated this skill, the haze in her mind started to disappear.
But the speed of it happening was very slow and it might need a long time for the haze to completely disappear. That was why Azusa immediately started to research a new skill based on the Heart of Valor. This new skill had to be stronger than the source.
This was not an easy thing to do but Azusa was not known as a monstrous genius for no reason. Even if she was not as broken as Elena, her own talent and abilities were top notch in the universe.
