Tsuuma and Me(su)mu?

[thecert]

Can anyone point me to a canon or even semi-canonical source for the names of Viral's wife and daughter in the "sweet dream" sequence? The only nearly official place I've seen a name for either is in translated credits for English-subbed versions of "Viral's Sweet Dream." I want to see these names in a Japanese-language source. An online or a paper source is fine (as long as it's not too hard to obtain).

Thanks!
