Welcome to Gaia! ::

I've met all of them, also. ^^
I've met each of them twice.
In my experience I've been pretty lucky, I've gone to two shows two separate years, managed to grab VIP tickets twice, and they've All went to both meet-and-greets.
Shaken hands with Kyo and Die twice, and the rest of the guys once each. And my first show... That's hard to explain shortly, but I was insanely lucky.
Simply, I was so nerve-wrecked and excited that while trying to contain myself I forgot to give Kyo the gift I brought him, since I'm pretty poor and barely afforded the VIP ticket I just brought something small, but I wanted to bring him something because he inspires me so much. Anyway, getting of track, I asked the venue staff if someone could give it to him, and they were insanely nice to me. Because I had been near the end of the line anyway, once everyone went through they let me back in to the meet-and-greet area and I got a chance to give Kyo my gift. Nora translated and they were both so nice, and I don't know where I got it from but I asked him for a hug. Surprisingly he let me hug him, and it was a nice light hug, but, mind you this is my first show and first time meeting them so I was completely out of it and I'm surprised I wasn't crying, I could not control my excitement for the love of god and squeezed him lightly for a second before letting go. Another thing to my surprise happened, him and Nora both chuckled at that, and it got a smile out of him too! I was shocked, to say the least, but that's honestly been one of the best experiences of my life, the fact that something I did made Kyo smile, haha.
So... that sums up my experience on the first time I met them, sorry about the length, but that was a short version ^^;;
The second time I met them was this past December. I gave Kyo a small octopus key-chain and he put it into his pocket, not onto the thing where all the members put the gifts where their staff took it away from. I felt kind of special.
Kyo has a really sturdy handshake, if you haven't shook his hand yet, get ready for it.
I like Die's and Toshiya's handshakes.
They give you great big smiles and it's pretty awesome.
Remembering meeting Toshiya is always fun, because he's so goofy and sweet, he'll be constantly smiling unless he gets confused, ad when that happens it's adorable. He's like.. like a puppy or something. Really nice guy. He was talking to a friend of mine after a show a long time ago, they were all outside and Toshiya was saying how he liked my friend's hair. It's great when people aren't rabid fangirls (though I've had a leak-y fangirl moment in front of them, it's not regular for me, so I deny anything linking me to a rabid fangirl syndrome) and the members can actually relax and be nice, cuz they're pretty great people.
