I was watching GGAC matches on youtube one day, and I was really impressed with Kaqn's Jam. Upon searching his name, I stumbled upon a video or him playing Ragna vs Reria's Nu... it was the first time I had seen a BB match. Nu's blades were coming out of everywhere on the screen : in front of her, in the sky, even from behind Ragna himself... and I didn't understand how the hell he did that. I was so impressed that I decided right then to main Nu in the game. Then, while learning more about BB, I discovered Rachel : a goth loli who beats up her own minions. I was sold. Eventually I found her micromanagement type of gameplay really fun, even moreso than Nu's, so she became my main and Nu became my sub.
So I unknowingly ended up with the two most broken characters in the game. I stuck with these two for CS, and while it's been a really painful road as a Rachel mainer, I feel it has forced me to surpass myself in order to be able to squeeze out wins, and with BBCS2, there seems to be light at the end of the tunnel...
