It actually is an odd story when you look at it like that. Basically, I didn't get serious about fighting games til CT (I started with SF4). Since I was still a noob and a scrub I went with Ragna til I learned the ropes. In CS, I found his playstyle boring so I switched to Hazama cause I could play him anyway I wanted to. In CS2, I went to Tsubaki because I always wanted to main her but I could never do 22x on pad. Once I got a stick, she was easy for me to learn so if anything I'll stick with her through the rest of the Blazblue series.
