yes its from comiket. the file name to look for is [C76][ゆうきまさみ×kz(livetune)] COSMiCA/GUMI [TAK][85M]. livetunes next album "crosslight" will be on sale in a few days so keep an eye out for that one as well!
I like to imagine in another universe where anime is played as live action by anime-like people (with various hair & eye colors) and vocaloids and utau are real life singers, Gumi plays Ranka Lee for Macross or maybe her mom played the part. I imagine Gumi to be a rebellious character, constantly challenging the norm of society.
Kiyoko504 Rather different from what I had in mind. I mean everyone in the world would have those traits naturally. We don't have that. Although, maybe in the future, people may be able to make that happen. Or maybe everyone will have their hair dyed all the time with healthy chemicals.
