This is the Japanese promotional trailer from last year that originally caught my interest in the game. Embed related, but I recommend watching the hi-res 1440p version as well.
Indeed, it's going for a pretty emotionally heavy tone and I agree the fanservice shot feels forced, but it should be up to the art directors what gets in and stays in. If they catch criticism for it, that's fair and welcome. Criticising art is a lot more productive than censoring it.
One can also argue that the shot in question isn't too out of place because it's part of the magical girl transformation trope.

It's the sad thoughts in her head (as well as from the enemies she kills) that fuel her super emo powers or something.
