Added costume request tag as the artist commentary mentions that this outfit is from a different game, and not an original.

It's Morikubo Nono's Gift for ∀NSWER+ costume. Notably, Nono is voiced by Takahashi Karin, who also voices Kawakami Princess. Not sure if it's intended to also be a Dark Side of the Horse reference though.

Thanks :)
I figured it was IM@S related but I wasn't sure.
