The Brothers Tachibana - S1-E22
Continuity mistake: During the Triangle Jump (a manoeuvre that virtually any referee would sanction as unsportmanship conduct and dangerous play) one of the Tachibanas, wearing number 10, heads the ball for the other Tachibana...who is wearing number 10 too. (00:20:40)
Ryo Shoots an Own Goal - S1-E23
Other mistake: After the own goal, Misugi and Yayoi are talking. Behind Misugi, someone is holding a small book open without using their hands. (00:15:30)
Ryo Shoots an Own Goal - S1-E23
Other mistake: Ishizaki's entrance is completely different from the ending of the previous episode; he just walked in while Tsubasa was talking with the Tachibanas, while in this episode he stumbles and everyone including Tsubasa is looking at him. (00:03:30)
Continuity mistake: In an act of murderous unsportmanship, Nakanishi damages the pitch trying to smash Tsubasa's leg. The pitch is pristine in the next shot though. (00:09:10)
Continuity mistake: Wakashimazu (not yet revealed) is watching the end of the match on TV. His travel bag is on the right shoulder, as opposed to the previous episode, but gets back on the left side in the next shot. (00:10:00)
The Best Keeper of the Tournament - S1-E25
Continuity mistake: Before the opening of the match, Jun Misugi's jersey has a yellow collar, instead of its standard white. (00:06:25)
The Fight for the Final - S1-E24
Continuity mistake: There are 5 kids hitch-hiking. 3 hop on in the front of the truck...and 3 on the back. (00:14:10)
The Fight for the Final - S1-E24
Continuity mistake: In the first shot of the hitch-hiking, the kid on the far right has dark blue pants instead of the light, greyish tone of the rest of the scene - compare it with the kid next to him, whose color is consistent. (00:13:20)
The Fight for the Final - S1-E24
Continuity mistake: After the match against Hanawa, everyone is in the dining room. They are asking Misaki if it's true that he'll leave soon. Teppei Kisugi has his arms on his knees in the first shot, on the table in the next shot. (00:09:40)
The Brothers Tachibana - S1-E22
Other mistake: When the Nankatsu player is injured, Genzo reacts to the event watching it happen through the TV - but he shouldn't be there watching the match, he said he was going to train instead. The next episode in fact shows that he missed the goal and therefore the injury. (00:21:40)
The Brothers Tachibana - S1-E22
Revealing mistake: In the very first move by Hanawa, Misaki and Tsubasa fold back before the twins' dynamic advance. Due to an animation error, Taro Misaki's hair in the wide shot flickers of a different color several times. (00:12:40)
The Brothers Tachibana - S1-E22
Character mistake: The Tachibana twins' play leading to the second goal is called by the commentator as "on the limit of the offside", but that does not make sense; there are a bunch of players in front of them, it does not come close to being offside. (00:06:50)
The Brothers Tachibana - S1-E22
Other mistake: Nankatsu scores to a goalkeeper that is wearing number 7 (obviously a poorly drawn 1). (00:08:25)
The Brothers Tachibana - S1-E22
Audio problem: Hanawa's number 8 passes a long ball shouting the names of the twins, but without moving his lips. (00:06:40)
The Brothers Tachibana - S1-E22
Continuity mistake: Ishizaki listens in disbelief to his coach saying that Hanawa is the strongest team of the group. He points at himself, then in the next shot his arm is already down his side. (00:03:30)
Other mistake: Behind Ishizaki on the bench as he incites Tsubasa in the last action of the episode, Manabu's legs and feet do not link correctly (something went wrong in the drawing, he's sockless all of a sudden and the ankles are much wider than the feet). (00:19:25)
Revealing mistake: Taki dispossesses an adversary, and promptly two more run towards him. The animation skips during their run, with the advertising banners changing color between two frames. (00:06:25)
Continuity mistake: The hirsute character next to Sanae and the other cheerleaders has a yellow sleeve at first, then grey. (00:06:15 - 00:07:00)
Continuity mistake: Ishizaki makes an upbeat comment about Morisaki's performance, but Manabu takes exception. During the exchange, one of the boys in the background has green pants that turn blue and green again. (00:05:30)
The Verification Test - S1-E16
Continuity mistake: When Morisaki catches the 90th shot, there's nothing on the field as he falls, but in the next shot he lies prone surrounded by footballs. (00:18:35)
