Welcome,
Aoi-luver!
I'm relatively new to the GazettE, too. When SongJapan revamped itself I got cut off from information on Japanese music. So when I discovered that there was an abundance of JRock on Youtube, I went wild

. I've liked JRock for years now.
JRock isn't that popular in the UK. At least not where I live, anyway. So finding new bands and music is up to you, really.
Anyway, back on topic...
Favourite member?
I don't have one :S. For once, lol. The band wouldn't be the same if ny one of them left. Where would we be without Reita's charisma and masculine vibe? Without Kai's smile and laughter, Ruki's emotional vocals and lyrics, Aoi's wackiness, or Uruha's...thighs? Heh, Uruha's
uniqueness. Choosing a favourite member is like choosing a favourite child or parent; it's difficult, if not impossible.
But I do like Kai. It's something about his smile and just general...happiness. It seems contagious, lol. And Reita, who I can't describe with words. He's...fun. That's the closest I can get, lol. Adorkable? Geez, somebody help me out? :S
Favourite song?
Um...probably Cassis because it's the first one of their songs that I actually fell in love with

. It's just so beautifu,l and the lyrics... And I love Reila for more or less the same reason. And I love Zetsu, too

. And Filth in the Beauty seems to have staying power in my favourites book.
