Good points there, Oppenheimer. My only problem is that his mustache looks fake..considering his hair is not black. But oh well. And I don't think that just because that one guy in Suikoden V is a flirt, it doesn't mean that he's not a narcissist. Augustine, as was quoted above, wanted to make many friends, and Vincent was so wrapped up in acting as if Tir was his best friend. So, I don't think that you have to hate everybody else to love yourself more. It's just my opinion.
I do think, although, that the purple haired lady is the narcissist. She seems to be very much into her appearance, but this is just pure guessing. She reminds me a lot of Estella...but then again, Estella didn't seem like a narc to me, just a chronic liar.
