I actually don't believe he is more GAR than Kenshiro. But he is GAR enough that the only one that should beat Hosaka in his block is Kenshiro.
But Hosaka has that certain aura about him. If you can't connect to it, well, it just means you can't.
Other than that, of the remaining ones left, Lord Genome, Kittan, remotely Medicine Seller should be more GAR than him.
But you can't really fault Hosaka for Kenshiro losing to a faggot, or Graham losing to a sweets addict.
But besides all those points, Hosaka is undeniably MAN, GOD, and EPIC. Enough for me to vote for him till the end.
