>Ki-61 being able to keep up with and destroy P-38s (and later Spitfires)
LOL, what "GRORIOUS NIPPON SUPERIOR OF FILTHY GAIJIN" wishful thinking this is. Considering how much faster P-38Ls were (about 50 knots faster at 10,000 higher feet, no less) and they weren't made of rice paper soaked in gasoline - it's no wonder that very few combat loses from Japanese fighters occurred in the PTO. Just from searching pacificwrecks.com which has a day-by-day combat record of the PTO (including sources from Japan, Australia, British, and American sources) - I can't find any confirmed kill of a P-38 by Ki-61s. Maybe I missed it, but even if I did, I can guarantee you that more P-38s were lost to ferrying flights than to all Ki-61s. This is the same aircraft that was most "infamous" for being used to ram B-29s late in the war.

>N1K2 (which, granted, was a dangerous and well-designed aircraft that could actually compete with late-war Allied fighters... unlike the Hein) piloted by a girl sitting on top of another girl while holding a rabbit and not even strapped in manages to out-maneuver multiple Spitfires
...Japan. Japan, plz...

And at least Girls und Panzer addressed the whole "girls shooting at each with live ammo" bit SOMEWHAT by stating that safety devices were designed and used and at least you have armor protecting you. Any actual machine gun fire is not going to be negated by aircraft "armor." And we all know how well-armored WW2 Japanese aircraft were... I'd definitely have no qualms about receiving machine gun and cannon fire in one of them, wouldn't you? (Makes you wonder if they skipped the bit where Motoko was using a sponge and shop-vac to clean the previous owner out of the cockpit and hoping Maki didn't pay too much attention to the patched holes in the fuselage...)
This manga is such utter trash. [continues reading it eagerly]
