Yoshimitsu looking to punish Kazuya Hellsweep (T8)

So, basically I play tekken 8 with a friend who is quite good. Like really good.

I play with him a lot and I memorized a lof of his patterns but I am not that combo savy.

I know that when he dashes at me he is either coming with a Hellsweep or an overhead kick; i usually block high because I can react to the hellsweep, my issue is I never manage to truly punish him after the hellsweep; I just punch/poke him and we return to neutral. I am sure he would respect me more if I truly punished his Hellsweeps.

Any combo recommendations against his hellsweeps? (That helicopter rpundhouse kick that Kazuya also uses in smash). Just reminder that after blocking I am in crouching state.

He usually is crouching after the hellsweep top.

Thanks beforehand!
