Wow lots of improvements. I'm surprised.
Less stance when you're far away from them. When you hit with 6B, do 662A for the frametrap. I saw you go for something else and he mashed on you when you were +3...
Don't put them outside of the corner with his combos. Do the combo in a way that gets you corner carry. Hitconfirm better. All those 5B starters were going to waste. Don't just chain in after a blocked chain. You can bait out Ragna's ID if he tries to anti air you with it by following it up with C instead of D. If he respects your options after 6A, do command grab on him more after you land it since you can't get anything off of it without meter or CH. You can command grab after a blocked Ressenga as well and if he tries to mash anything but reversals, he gets caught. Try different chain ins. Get less predictable with your chains. Cutting your chains short can lead to surprising results and are far less predictable if you know how Hazama's D moves work. Use different follow ups like B and C, do double followups and use a varietion of B, C and D followups to catch your opponent off guard.
As for j.6D, how are you trying to do it? Are you mashing it or are you holding up and 6D? Neither work for me so I have my own way of hitting it and I never miss this link (His 5C > Jakou > 3C > Mizuchi link is harder imo). What I do is just have a sound cue (du duh(6D)... duh duh(4D).. duh duh(j.7D)..... Jakou... ding.. j.6D) You could find a visual cue for this link too and that's how I do the 3C > Mizuchi link at the end of the combo.
