Hah, not weird at all! One of the many reasons why I loved Judai as a character — and subsequently fell in love with GX as a whole — was because KENN did his voicework. His acting during the Haou arc still gives me shivers, to this very day. :)
Indeed. You gotta hand it over to seiyuu that could voice high pitched shonen characters, their deep voiced evil sides and sing all at the same time.
KENN has absolutely amazing range. It’s just a shame that so far, he seems to have been pidgeon-holed into 'hot-blooded shounen action hero' roles, post-GX. I would give almost anything for a series where he plays a villainous character of any stripe (and no, Kyoukai no Kanata doesn’t really count).
Well, if you want to hear him in a non-hero role, you could check him out as Kouki in Digimon Savers; it sounds like a cross between his S4!Judai voice and his earlier tone for him lol. He’s in there for about 10 or so episodes, too, and so is Takanori Hoshino (JACK!!, Honest) as his ally Ivan.
