I think the Girl from Saunders was the one that " cheated during their match against ooarai aka was willing to do everything to win because war knows no rules "
And in ch 1 the protagonist deployed some questionable tactics as well so they are kinda similar.
I like what i see so far. But i do wonder if that foot fetish will distract the driver in a critical situation someday^^
Been awhile since I last watched S1 Girls Und Panzer and don't quite remember all the names. But Matsukaze-san looks similar to Yuzu from Citrus: http://dynasty-scans.com/chapters/citrus_ch01#3
Also from another manga that I cannot remember of.
This is interesting read tho.
