Kyoteki! Ankoku shiten oh arawaru - S1-E9
Factual error: Unless the police dog is also a Saint with extraordinary powers, it's kinda impossible that he'd have followed a scent over 6 years old, through a public park even. (00:13:40)
Cygnus! Hyogen no senshi - S1-E3
Factual error: When the camera pans across the boxes from networks all over the world broadcasting the Galaxian wars, clocks have nonsensical hours; it's 10:20 wherever "ACO" is from, but 5:05 in "MHK" land. Timezones don't work that way. (00:10:45)
Yomigaere! Eiyuu Densetsu - S1-E1
Character mistake: Not to dispute physics in an anime about people drawing arcane cosmic powers from constellations, but when Marin explains to Seiya what happens when you shatter a rock into smaller pebbles, she says that you "destroy its atoms." That's not how physics works and luckily for her, Seiya and everyone else in Greece at the time, she did not create a nuclear fission in the palm of her hand just to prove her point.
