This is the fourth time I've seen a Blue Archive character cosplaying as BeelStarmon here (all from different artists).
Wonder if there is an art trend going on or someone commissioned these artists.

Nah. It's just a result of Time Stranger being BeelStarmon's first showing outside a card game and wildly successful (at least by the standards of Digimon videogames). Now there's a lot of interest in her and her "distinct" outfit, and BA happens to have plenty of gun-toting girls who can make it work.
