The long-suffering Kiyone and her idiot partner, the bad girl pirate Ryoko... and my personal favorite, Nagi. She's a bounty hunter, she's got her own cabbit, and have you seen her in a swimsuit?
I remember seeing this show on Toonami back during my short venture in college, watching it at home, borrowing a copy of the Christmas movie from a co-worker, and to this day, it stands as one of my favorite series.
Call me old-fashioned, call me old-school. But this show's just been... it was the show that really hooked me on anime. It just had everything I needed at the time.
That's it. No real plot, no real question. Just my declaration of love for my favorite anime of all time.
