Who's the one with the swords in them suppose to be? They have Noel's hair color (Lighter than Lambda's.) but Nu's outfit.

It might be an earlier version of the Murakumo series. Calamity Trigger mentions that Ragna destroyed two Librarium branches before arriving in Kagatsuchi. She could be one of the unlucky ones.

I believe that's Jin dressed up as one of the Murakumo series, trying to get closer to Ragna. (Clearly his plan failed)

Note the less slender and more masculine-shaped arms, as well as the lack of a chest.

Wow, it probably is Jin.

Not that with this set of girls there is much of a chest to notice.

And to think; most of those could be called his "sister".

a big happy family

i dont think anyones really sure anymore, especially since its pretty obvious ragna was created not born

Might Ragna himself be a murakumo since he's listed as #5? Jin and Saya might be by extention of the early units that were thrown into the boundary.
