When Desire went back to find the Elves who were supposed to be in the room, he...found out that they were no longer in the Lord's mansion because of Ryu.
Ryu was staying at the entrance of the mansion to keep guard and to supervise the surroundings, and he came out to meet Desire and Jarina when he felt that they came back.
Of course, Desire asked straightaway about the Elves, and Ryu answered him that the Elves...were no longer in the mansion and that they are together with Amelia, working things out with the other Elves somewhere in the city.
When he learned of this fact, Desire was annoyed by Amelia's efficiency and diligence since it would take him more effort to see the two Elves now.
Well, he wasn't really annoyed, but...it was the truth that it would take him more effort now.
Nevertheless, Desire still ordered Ryu to come with him as he asked for the directions where the Elves and Amelia are located.
