My old username was Kagamine cuz I was in the middle of a huge Vocaloid phase back then. A lot of people just called me Kaga, though, which actually managed to spread to my IRL circle of friends, as well. Pretty much all my friends just call me Kaga now, even the ones that don't know the origin of the name.

The Vocaloid thing died down considerably actually a while ago, plus I started thinking the name was kind of unoriginal and dumb. I started preferring 'Kaga' even back on the old Guild, but it was too much of a hassle to change. Rebooting the Guild was a good opportunity, though. Besides, I feel like 'Kaga' has a nice ring to it.

As for the avatar... I just like Trigun. That's all.
