For some reason, because of the author's artstyle, this doesn't feel like Girls und Panzer at all.
TBCH, I feel like, if I hadn't read the tags, I would've comfused the blonde one for a certain het girl from a different anime named suspiciously like the old name of the most populous middle eastern nation.
If only we have a fanfiction of Saber Lily meeting Saber of Red due to time travel or parallel reality with yuri of course.
Reaction would be quite interesting sigh.
