Julian

Julian mostly appears composed at work and is very mindful of team spirit. She may only be a vice-captain in position, but she shares a lot of Shizuru's captain responsibilities without complaints, and even though she loathes socializing as well, she mastered the art of making small talk since Shizuru genuinely isn't able to do so.
Julian sometimes bears the responsibility of shooting Dorothy's thrown explosives in the air, as her forte lies in archery, and she will also shoot to hold up enemies alongside Karen. This has sparked off some talk about her being a 'doormat' who lets people walk all over her. She never refutes it when she hears it, only saying blandly in response, "I guess that could be it."
However, someone in B.C.R.L. has discreetly shared that anyone who has seen Julian mad will never dream about upsetting her again. The muscle lines on her arms seem to subtly back this up, too.

"Julian is actually a terrific fighter! I heard through the grapevine that during training camp, someone tried to... and then she smacked that person down with a BAM!" shared a certain blonde demolitionist, who declined to be named, to the Conductor.
Verily, Julian's physical fitness and fighting skills are relatively impressive, but she refuses to put down her gun no matter in what circumstances these days.
This all could be traced back to when she was still tumbling in the mud of the slums. She happened to meet her neighbor, a mysterious middle-aged man, who had appeared out of nowhere and, for some reason, suddenly assisted her as she was getting beaten black and blue. The condition he proposed was, "If you trade me something, I'll teach you how to fight."
Hence, using the cigarettes she secretly stole from her father, Julian did the trade with the mysterious neighbor and began learning a one-of-a-kind fighting technique from him. As she eventually mastered it, the neighbor vanished as abruptly as he first appeared.
Only when she applied this fighting technique in real life against someone did she realize how its power far surpassed her comprehension of it, to the extent that she nearly terminated that person's future in advance. From then on, Julian laid down strict rules for herself and vowed not to use the technique unless in emergency situations.

If you have the opportunity to get your hands on the registration form Julian submitted when she joined B.C.R.L.'s training camp, you'll discover something interesting: The name written beside the photo of the steely-looking girl isn't her current cool-sounding 'Julian' but a run-of-the-mill girl name "Xiya." It has never appeared in any official name lists again ever since she officially joined B.C.R.L. and changed her name.
To Julian, Xiya isn't a name she dislikes; her father and people who knew her as a child still address her by it to this day. But the experiences she had as Julian are irreplaceable, although this was initially only a name meant to signify her new life and identity and a part of self-preservation, just like her impassive, overbearing attitude. The intense training she underwent in the training camp and the emotion-laden way her pals called out this name... These are what gave the name meaning and played a part in creating the present Julian.
Nevertheless, even someone who's constantly strong like her has times when she needs to take a trip down memory lane. Julian will entrust the name "Xiya" to her trusted companions and have faith that they will protect it the way they do a treasure.
