I assume this is trying to be accurate to DFC, yea? I'll boot up my copy tomorrow and give better feedback. But for the time being:
You shouldn't be able to combo after the last hit of her Trump Card.
Speaking of, I don't remember the last hit being active for so long.
Supers should only be done with a+b. I'm having problems doing her Climax Arts because of this.
I could've sworn you could do her Trump Card off of EX One Hand Shoot.
Opponent can tech during just frame Impact Skill followup.
5C is the only air blockable normal. 5B/2B should be the only unblockable ones. (Or maybe just 5B, but I know some characters have 2B unblockable so I assume it's universal.)
I don't think EX One Hand Shoot had such huge range for the initial hit.
Frame data is wrong. Recommend checking this. http://wiki.mizuumi.net/w/Dengeki_Bunko_Fighting_Climax/Tomoka_Minato
