Revealing mistake: The animation for the news reports shown on the television are incredibly cheap and simplistic. The design of the reporters and the background behind them is far from finished and does not appear realistic in the slightest. Also, everything that is shown on the television is just a still image where none of the people in it are shown moving. (00:10:12)
Continuity mistake: When Mima is in her apartment for the first time, there is a shot of her placing three letters on a table, on top of each other. The letter on the bottom has a pink envelope, the letter in the middle has a white envelope and the letter on top has a blue envelope. In a wide shot of the room a few seconds later, the envelopes have changed order. The blue envelope is now on the bottom, the pink envelope is now in the middle and the white envelope is now on top. (00:09:47)
Revealing mistake: When the crowd are booing the hecklers, in a wide shot, most of the people are drawn without faces. This is even more noticeable when the crowd turn to Mima after she shouts at them. There is also very little detail is put into the animation of their hands, they come off as stumps attached to their arms, with no fingers. (00:06:26)
Revealing mistake: At the concert, when the hecklers are throwing the cups and cans at the crowd, and the crowd are doing the same thing to the hecklers, we can see many of the cans literally pop into frame when they are being thrown, and pop out of frame when they are close to landing at the other person. Clearly the cans were only drawn into the shot whenever they were being thrown and not whenever they came close to landing or before being thrown. (00:06:26)
Revealing mistake: When Mima is at the supermarket, virtually every character shown standing in the background behind her is completely still and motionless, with no signs of body movement in the slightest. (00:03:34)
Revealing mistake: When CHAM first go on stage, many of the extras in the crowd are drawn without much detail put into their faces. Also, despite them cheering and being extremely excited to see the trio perform, they are shown standing completely still and not moving whatsoever. (00:02:30)
Continuity mistake: When the guy at the concert is trying to sell the three remaining magazines, in the close-up shot of the magazines, he is holding them by the top of the page. But in the next shot, he is suddenly holding them by the bottom of the page. (00:01:20)
