Singing inside an abandoned theatre. I mean, definitely a good way to train yourself to get used to one when you don't have any other options.

"A diva who became reborn into the virtual world in order to fabricate a new world. No matter the time, place, or position, she warps through all the barricades with her dazzling talent."
—AZKi's official bio

AZKi is a holomem with one of the more enigmatic character lore in the agency. Is she human? Her bio could be interpreted figuratively or as is.
At any rate; this has little to do with the picture; after XC3, this fanart always reminds me of the Moebius lol.
Beautiful art.
