Need help with Kingpin Advanced Juggle

I don't get the timing at all.

Can somebody please tell me when to press "V"

and maybe show me ig if possible*

 

It's pretty simple u press v as soon as u press the last hit in ppkkp
So it would go kkp p p ppkkp v

 

If you're going for one of the grab advanced nanmus, slow the combo down a little and press the nanmu button right after you press the button for the grab part of the combo.

Nanmu right after you press the button, but before the grab animation connects.

 

Any scroll that has a grab-hit input in a combo can do these advanced juggles

The trick is to cancel the grab-hit with the nanmu

It's like doing a kG but instead grab-hit to nanmu
