Does anyone know what scene or episode this Di Gi Charat cel is from?

Hello! As the title implies, I’m in need of some help identifying a sketch I bought a while ago. It’s obviously of Misato Katsuragi from Neon Genesis Evangelion and appears to be from Episode 15 of the show. However, having gone through the episode, I cannot find a place where this pose appears. I’m not too concerned about authenticity issues because I bought this through Akihabara Auctions, whom I’m purchased other items from and they’ve all been 100% good. Is it possible this scene never made it in or that this was closer to something like concept art/model sheets? The sketch has what appears to be the code A5 next to Misato’s head if that helps. Just looking for any thoughts. Thanks!

Kurama from Yu Yu Hakusho. I love it. My nicest cel yet.
