Azaroth's involvement within the Sinyalian Kingdom wasn't guessed or suspected by anyone yet.
Not even Inquisitor Fox thought that Azaroth survived in this world. In his opinion, the creation of this Noble House's Alliance was quite natural.
Now that Edwin had been killed, Shun had decided to not involve himself in the politics of the Sinyalian Kingdom.
Azaroth instructed Bianca, and she carried out his orders perfectly. She asked her personal maid to carry out a couple of those orders.
Now that Azaroth knew how dangerous Inquisitor Fox was, he included this guy's presence in his plans.
However, Azaroth knew that this Inquisitor Fox wasn't the only obstacle in his path. There was still that Fate Energy safeguarding the Royal Family. And lastly, Tronte's true identity and motives still eluded him.
