who played Masaki Murakami in the ova?

the actor name in the credits is Steve Areno for the manga dub

but I checked the dub and I swear thats david hayter voice 

was murakami voice actor deferent in the us rendition dub? 

even david claimed in his twitter account that he played him and tried to asking him about this steve guy in the credit he did not answer 

There are at least two different dubs to my memory...

You 're not the first person to think it's Hayter: https://www.reddit.com/r/Guyver/comments/atqven/waitdavid_hayter_voiced_murakami/

Unless you're the same guy though.

I'm pretty sure Murakami's voice actor was left unchanged across both dubs. Most of the voice actors are the same in both. I also don't think it sounds that much like David Hayter, Steve Areno is a pseudonym used by Steve Cassling
