I actually share the opinion with Suka that Capu sucks, I do not like him

Her style is so good. The thigh high black boots, two-tone dress and the typical style we'd expect. Birgit has amazing mod/retro style and I felt like she was familiar.

When she approaches Chain to thank her awkwardly for saving her life, she is wearing another mod/1960s style outfit. A coat, mittens and pillbox hat.

And then my brain went 'waaaaiiiiii - pillbox hat. Duh.

Birgit's character design is taken from Trigun. Specifically, Elendira.

All of Elendira's outfits are that mix of retro (1960s) and mod. Their long light colored hair has a similar length and flow.

In this chapter alone, it shows that Birgit is passionate and has a jealous side. Elendira was also jealous of Legato, fighting with him over Knives attention. The fact that Birgit was 1.) saved by Chain 2.) thanked her 3.) has a huge crush on her makes me think that we might be seeing more of her. The possibilities to use any of the points can definitely add to future chapters. There is also the possibility that maybe she's changed her approach to things. Taking the time to show her thanking Chain is interesting storytelling and does remind me that even though Elendira was the toughest of the Gung-ho Guns she did occupy a unique perspective on Knives' side of things.
