Leon alternated his mission from assassin to covert operation with Agents. He has already advanced to 2-Star assassin on Silent Serpent but his reputation wasn't worse than a 3-Star assassin.
His name has entered the rank and currently, he is ranked at 9235, which might be quite low but his rise in ranking was quite first.
Some assassins take months to complete the assignment but he hardly takes 3 days to max a week to finish up the normal quest.
He had already gotten rid of many people who exerted a great weight on the world by living on it so Leon decided to unburden the earth from their huge weights.
Criminal Syndicates, Mafias, Don, and Drug Lords of various places started to get afraid of getting killed by a headshot.
What was more terrifying, was the major chunks of people who died with their heads knocked by a bullet, but to their horror, there wasn't any bullet.
