Today I want to talk about Shiroko's hair. Shiroko Terror is a different entry on the wheel, so she'll be talked about another day. Shiroko has short, neck-length gray hair and wears an upside down, sky blue cross in her hair, on her left side. This cross is mostly centered, but is still slightly uneven- it's a very interesting hair accessory, because it's something of a leitmotif for Blue Archive. The logo incorporates this, even if that's GSC President's hair or Sensei temporarily being a shooting star. Perhaps this was designed to represent a glimmer of hope?
Shiroko's hair is relatively static through most her outfits, being short but slightly shaggy, making it obvious that she is, indeed, a wolf. If her personality didn't convey that enough. Interestingly, she flips her cross accessory so it's now right side up in her riding alt. Knowing Shiroko, it's possible that she did this for comfort, aerodynamics, or maybe she simply likes how it would then be pointing forward, to her next destination. Her swimwear has her accessory in its normal upside down configuration. She also puts her hair into a ponytail, likely to prevent her hair from getting in her way- a very practical choice for her. Even when she was a first year, her hair was mostly the same- short, slightly shaggy, and with the upside-down cross on her left side.
It's possible that Shiroko's hair is this short because it helps her get a more clean getaway from any banks she robs, but it could also simply be a fashion choice. What is most interesting, though, is how she doesn't really show her wounds- she may be injured, yes, but she still has a very "alpha wolf" look to her. She may have something of a simple personality, but it's quite passionate where it shows.
Due to her personality, Shiroko doesn't have a particular scent to her hair, likely so she can both more effectively scout banks, but also because it doesn't seem like something she'd concern herself over.
And for completion's sake, her mahjong outfit. It's very simple, but has an interesting juxtaposition- her somewhat wild front, and a traditionally tied back.
