Even better.No, that's MoM's seiyuu
Edit.
Seiyuu=voice actor btw
And I think with this we can finally confirm that the MoM is not Demyx since their voices are really different. At least in Japanese, I don't remember MoM and Demyx voices in English
Through I'm not sure about it ruling out Demyx as MoM. After all Xigbar and Luxu have different VAs as well
