Eric was the guitarist in a metal band, a very famous band by the way, especially in Japan where they were natives. But he was a little too arrogant and debauched. Recently, a new member was announced, a new vocalist! Of course at first he didn't agree with it, but everyone else seemed to like the idea, so he had to agree. "We don't need someone new, we're already famous without him/her." Eric retorted, obviously not in favor of that.
