Today I want to talk about Tsurugi's hair. Tsurugi has exceptionally long hair- maybe not the longest hair out of every student (I'm pretty sure that honor goes to Makoto), but close to it. Tsurugi's hair in her daily outfit is similar to her wings- long and relatively thin, likely on account of her unique fighting style cuasing it to go all over the place. While that might cause her to potentially blind herself now and again, it might actually serve a purpose if she moves fast enough to cause her hair to make her outline misleading, causing enemies to miss her, similar to Otogi and Miyu, but applied differently. Her swimsuit has her tie her hair up into a ponytail which shows that her hair is rather thin for its length, which makes sense with how her normal hairstyle has her hair taking many different directions. Another unique thing about Tsurugi, though more about her halo than her hair is that while it seems to drip onto her, it doesn't seem to perceptably change her appearance or mentality- if anything, it's likely the other way around: her manner of fighting formed her halo to become what it is. This is mainly to say that it likely doesn't make her hair smell different. And Tsurugi's hair almost certainly smells of roses after she cleans it. Which, considering how much she does, and how long her hair is, she might be the student who takes the most care of it. Sure, it's not dyed, and it's definitely not going to be perfectly in order whenever you visit, but her work can't be understated!
