The awe and wonder that the players had for Adrian made them inspect him immediately. Some were successful while some failed to even get his name. Since Adrian is a greater demon, only those with persona that is equal to him or someone with high tier appraisal skill could get his information.
"Equinox! He is the owner of that wolf! Get him!" Someone who managed to appraise Adrian's information shouted which made the players enter battle mode.
The others however did not immediately attack Adrian because they were wary while some were interested in him. The prospect of becoming another race has always been in the eyes of the top guilds which is why they did not attack him immediately.
