Leonel decided to let Eamon off the hook. He didn't really need to know, honestly. Given the circumstances, and the risks Eamon was willing to take, this was obviously someone he cared deeply about.
As for the matter of the Bull Demon being a Low-Class Demon, he wasn't very shocked by this either.
The demons were a powerful race overall, and the Bubble Worlds of demons acting now were unlikely to have demons stronger than the Low-Class.
This was to mean that most of the fighters were probably Lower Low-Class Demons, with the strongest probably being Middle Low-Class. There might only be one or two Higher Low-Class demons if any at all.
