Just gonna throw up a combo that I got messing around with the AI in training.
STARTER -> Renka (1) -> Kishuu (1), 66 or 5, 5C -> Kishuu (2), j2C, 2C, j2A AD j2A, j2C, 2C, j2A, AD, j2A, j2A, j5C
5 Stars and roughly 5200 damage. I'll update it when I can get on blazblue again, I might have messed up the corner loop sequence. Just know that you corner loop at the end. It can carry the opponent from the starting point of the stage into the corner even if you don't use the 66 dash after the Kishuu. I got inspired from watching the Chin vs Sakamoto matches. It's a little simplified, but it works and doesn't require many advanced techniques like IAD or TK Hotaru/Tsubaki. The only problem is that is probably not the most efficient use of magitama. Hopefully it isn't against the rules.
I'm still practicing it in training, so I'll post some more after I can get it to work in matches. >_<
