That was definitely not a whiff XD When Naotora gets an opponent near the wall with the move it should "cage" them in place like the other stages do, something is wrong when it's literally within hit range and then the game magically has you switch positions, it wasn't supposed to whiff at all
Oh right XD sorry I meant 6K4K>KKKKKKKK, but you can't use that since the fourth hit wallsplats, but I do know there is one manual combo that surpasses IFC kick input. And yeah the IFC K is universal and good for heavyweights. I'll have to look later on today when I get home after I play some FFXV XD
Afaik it's not just this stage, and actually, the combos you mentioned do way less damage than IFC K and only work on Alpha I think. IFC K is just the best option against a wall, both for max damage on every weightclass and advantage aftewards (because no WU kicks), , making this "whiff" thing a bit annoying.
The most damaging wall PL manual combo I could find was something like 6K4K > 6K4K > 6K4KK (on Alpha), but even that does not surpass IFC K.
I guess the best thing to do when on this stage after a PL is 6H>6K4K>KKK6K~K/KKK4K. XD The IFC thing is easier but a manual combo does have more damage potential for everyone but heavyweights
You can't even imagine how many times this actually happened in a match. I don't think it's a glitch though, delaying the K can lower the chances of this occuring, or at least it kinda works for me.
Also, you can't backdash since she's in the Ii stance.
