Shito! Kyofu no kokushiken - S1-E11
Other mistake: As they are making their way to the designated place, Tatsumi and Saori explain the lovely place called "Murder Valley" is not on any chart, and the locals keep away from it because everything in it dies. They reach it by helidrop and surfing on glaciers. When they are there - in the middle of a wasteland that pumps out sulphur - Ikki is more precise about the spot where they need to meet; the "Shishigabana stone." Seiya and Hyoga wonder where that is, to which Shun simply says "It's a famous stone in the Amidagahara Wetlands [...], my parents took me to that location a very long time ago." It's Midagahara, and if the location is so close to a place familiar to Shun, you'd think he would at least say something. Moreover, it's clear from the rest of the series and manga that Shun is never supposed to have parents who took him hiking - even irresponsible ones who'd carry him near death pits. (00:04:20)

Audio problem: Hyoga butts in with "What did you say you just saw, Ikki?", but Ikki was THINKING that phrase about seeing the battle, not saying it out loud - unless he was practicing ventriloquism without an audience. (00:21:50)

Plot hole: Changes made in the anime only make nonsensical the mechanics of the fight against Black Pegasus. The villain focuses on dealing one big hit to the side of the hero at the cost of his life, but that big hit happens just in the anime and has no consequence or purpose at all. Seiya collapses later with various black spots from the hits of the first barrage, the one that he thought gave him no damage and went instead under the armor, just like in the manga. Black Pegasus had already dealt his death blow by that time, and what he does in the anime in addition to that has no consequence or meaning.
