Yuki gave the new girl a little wave as she walked by but didn't say anything. Partly because the question she would have asked, Kyo already did, and partly cause she was distracted by her 'in kit' Sengoku Astray custom, it was mostly done, there was a piece for the back she'd probably need to fabricate her self. 

Hopefully the school had a 3D printer for such things cause she REALLY didn't wanna go through the process of making molds for one part.
