An embed of the character Tia from Rage of Bahamut and/or Shadowverse or even Granblue Fantasy. Cygames does like to reduce, reuse, recycle.

Her dress comes in two flavors in her official art, a dark one and a lighter blue variant. The embed is biased towards the dark dress, but if you want the light blue dress you can get it with enough prompting and rerolling.

Trained base NAI, full prompts.
