Was just messing around with this for the first time, but what does it for me is inputting the dash 'as' you land and the kiss when shes fully planted on the ground if that makes sense.
Also I noticed dash 2kiss seems to hit every time and does 3% more damage than dash kiss. Is there a reason to why this is avoided? Literally just picked her up so have read pretty much nothing but this thread. Sorry if it's explained somewhere else
Edit: it might not be more damage through the full combo but is 2-4% more up to the cartwheel depending on where you stop or drop the combo. I, for the life of me, cannot get b21f2 after that cartwheel lol
Definitely seems to lose the extra %. ending the combo with an uppercut after the cartwheel leaves it at only +1%, but it does seem easier to land than a naked kiss
f2kiss seems even easier to land
