Ryu sent a glance toward Ailsa. But, she didn't seem to take his coldness very seriously. After getting used to Ryu for so long, she had learned to shrug off such things long ago.
Ailsa knew exactly what Ryu planned to do. He likely wanted to use the resources of the Mercenary Guild while keeping a low profile. Even if he had a chance to use his status as a Direct Descendant, he likely wouldn't unless he had no other choice but to.
However, in this situation, his status was all but exposed.
Ailsa pretended like she knew little about the Mercenary Guild. But, despite having spent most of her life in a deep sleep waiting for Ryu to reincarnate, if there was anything she did know about, it was these large Guilds.
The Mercenary Guild was large and expansive. It couldn't truly be considered to be a single power. Rather, it was the combination of several, thus their factions.
