I'm a guy, Miyavi rocks and I have no shame admitting he's hot (well as far as guys go LoL)
Ah Miyavi... I like some of his songs (Freedom Fighter, Aho Matsuri, Jibun Kakumei, Merry Kanshimimasu, Peace Sign, etc!) but i don't really like Myv himself, and i hafta admit that i can't stand 99% of his fangirls neither.
From all the youtube clips that ppl put on about Miyavi, i think he does have a very unqiue style (image-wise, at least) The boy could play good guitar, though not 'the best', like alot of his fans claim.. and of course, alot of fan-girl is after his 'booty' as well, so it doesn't matter really whether he's musically talented or not =-p
