Yomigaere! Eiyuu Densetsu - S1-E1
Continuity mistake: When the Grand Pope awards the Cloth to Seiya, his necklace has 4 fuchsia beads on both sides. When he was displaying the prize early in the episode, his necklace had 3 of those large beads. (00:04:30 - 00:11:40)
Yomigaere! Eiyuu Densetsu - S1-E1
Factual error: When Seiya cuts off Cassios' ear, it pulses on the floor like it's a beating heart. There can hardly be a muscle twitch in a severed ear. (00:05:30)
Yomigaere! Eiyuu Densetsu - S1-E1
Continuity mistake: The Pegasus armor is contained by a box, metallic grey, placed on a slab next to the Grand Pope. When Seiya cuts off Cassios' ear, the box appears gold/bronze colored, and when he tells Cassios "I owe you quite a lot of payback", the pillar with the armor is right behind him already instead than the top of the stairs. (00:05:50)
Yomigaere! Eiyuu Densetsu - S1-E1
Continuity mistake: During the fight with Cassios, blood keeps changing position on the face of the beastly man, in particular on his chin and above the right eyebrow. He also bleeds profusely on his shoulder, and plenty at the beginning runs down his other arm and hand, but there's no trace in any of the subsequent drawings, only the face stays bloodied. (00:05:50 - 00:11:30)
Yomigaere! Eiyuu Densetsu - S1-E1
Continuity mistake: At night, Seiya is startled by Marin's voice and looks at her. There's a table with wine and fruit to his right. A few seconds later, in another shot of the room, the table moved to the left. (00:12:40)
Yomigaere! Eiyuu Densetsu - S1-E1
Continuity mistake: The octagonal ornament at the centre of the sides of the box containing the Pegasus cloth is considerably larger in the arena scenes compared to the scenes in the hut. Even worse, when Seiya runs away with it leaping over craters and such, it gets even smaller, and stays that way also in the following episode. (00:12:50)
Yomigaere! Eiyuu Densetsu - S1-E1
Continuity mistake: When Shaina launches her Thunder Claw announcing the name of the move for the first time, she has blood coming down her armpit. She'll get that wound only much later in the fight when Seiya punches from the bottom of the slope and tears her shoulderstrap off. (00:15:10)
Yomigaere! Eiyuu Densetsu - S1-E1
Continuity mistake: When Seiya reaches for the Cloth's handle, the box is approached from different sides in his POV. (00:15:50)
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.
