he is the silver blade after all.

Alucard obviously, theres nothing Jihro can do to stop Alucard at all

i think actually, it would be a tie. they are both very powerful. and you know who Jihro is??? cool!

Jihro is powerful but there is nothing he can do to Alucard, Alucard is omnipresent. Basically as long as he doesn't doubt his own existence he can never die or be injured, he can also be anywhere he wants instantly. Very few anime characters can defeat Alucard.

nobody perhaps!
