Azaroth spent quite a lot of his time with Sophie. For the first two days, the two talked about Kloras Town and narrated how their lives had been since the two went separate ways.
Azaroth gave her a basic story of what happened with him.
The two were walking around, talking about the array formations.
It was Sophie who was very interested in this topic. She told him about a new idea she had.
It was related to an illusionary array. She was wondering how she could improve it.
Azaroth didn't give her much advice regarding it. He had to show that he had little idea about the arrays.
If he really revealed his true knowledge to her, then she would be greatly stunned. And then, she would understand he was lying about his array formations' skill to her.
From what he heard, Sophie was planning to incorporate the illusionary formation with a killing formation.
