This reminds me of a show from a while back whose name I cannot remember, dammit, about a wandering warrior with a pink butterfly mark on her, who is blonde, stacked, and stoic, and being hunted by a bunch of other women who are stacked and gainax all the time, including especially one who fights with pistols.

What was it? I seem to remember that it just kind of ended, without really having had any point besides fan service overload. And the clothes they wore were equally useless for purposes of protection. It was more like "battle lingerie".

Not the one in the floppy hat.  She'll clearly be using glowy magic circles to block things.

"because she's using glue"

More detail is required.  For research, of course.  I mean, those could be piercings.

"whose name I cannot remember"

I'll guess "Blade and Soul".
