If I think about it, Asuka really is a 80s Hollywood action flick. Like literally. Everything fits so much, even Asuka's age:
Usually, JKs do not become Mahou Shoujos, but this is the job of JCs. But Asuka is still one, recalled back from retirement during her JK age to get the job done.
This is pretty much comparable with the Hollywod action hero trope, with the MCs who were some spec ops soldiers during their 20s, serving in the Vietnam War, but recalled back in their 40s to save the world from Islamic/German/Soviet terrorism (or whatever was the villain back in the day).
As such JK Asuka Mahou Shoujo literally is a 40-something hollywood action hero, who is literally too old to do that job, but still has to soldier on.
This really explains her stunning aura that attracts other girls in the cast, as well as her straight character. She is literally a grandpa who wants to go back to retirement and doesnt want to deal with the bullshit of the youngsters anymore who are invading her fucking lawn.
