After becoming Lord El-Melloi II, he takes on a reputation as a famous lecturer of the Clock Tower. His involvement with Rider changed his previous attitude, allowing his persistent effort to lead to him being called a professor. Known as "Great Big Ben London Star”, "Professor Charisma", and "Master V", he has been even named "the number one man female students would like to sleep with", among others. He cares little about his reputation, and he would rather focus on his own success as a magus. His irritations towards it has even caused people to say that he has walked through the institute with a constantly cranky look to him for several years. He is not an ambitious person, and he does not like to become involved with his students, having once said, "What a load of codswallop. Why should I, stuck at the fourth tier I still be, have to bloody look after other people?" He dislikes people calling him Lord El-Melloi without the "second" because it is unbearably grating without it.

He takes after Rider in that his sole pleasure lies in Japanese video games, though he has come to hate Japan and Japanese people.  He orders a large number of games, and after playing through them fully, takes the time to diligently give his thoughts on the games through their survey cards. Though he often receives game memorabilia through sweepstakes, he cares little for it and mostly believes that it is the proper action to relay his opinions back to the game designers even if he must pay international postage to airmail them to Japan. Much of his room is full of the memorabilia, though he also has a cabinet where he keeps the fragment of Rider's cloak that he used as his catalyst.
