The old man looked at Lucifer with a scary frown on his face.
It was so different compared to the look that the old man gave when he was talking with Rouge, who was just a random captain.
Of course, Lucifer was just new to the Warmester Denoble House, but...when compared to the head of the Warmester Denoble House, both Rouge and Lucifer would just look tiny enough that such a stark difference in the old man's behavior was...abnormal.
Right, that was how it should be. Just like how the old man was currently looking at Lucifer with disdain in his eyes, that should also be his look when he was talking with Rouge.
Lucifer knew this very well, and that was also why he was really weirded out by the fact that the old man...was kind to Rouge.
Of course, even though Lucifer never got any confirmation that the old man was indeed the head of the Warmester Denoble House or something like that, he still knew that this is the head.
