Judging from everything I have been following with this man and his character... It really does seem like the role was reserved for Toriumi Kousuke all along, but what are your other thoughts? In terms of bad joke connections and broken telephones with character and voice actor; I have quite extensive list on it.
Kubo Tite Favourite Seiyuu is Toriumi Kousuke?
Yes, They Share Same Initials
No, I Can't Stand His Voice
Other, Name Other Seiyuu in the Bleach
