>>4318304>Nan YaegashiHe's actually drawn Nep a few times, this one here is for the Senran Kagura mobile game collab with Neptunia. Although there was a whole SK x Neptunia game (it was... okay?).
I don't see SK collaborating with GuP any time soon but both series are kinda based on academies, right? It's not the most far-fetched thing out there.
