Revealing mistake: Whilst Rei and Yukiko are talking about Mima's photoshoot, there is a mirror shown next to them, as well as many objects shown on a counter beside the mirror. In the shot where Yukiko says Mima can't wait to strip in front of the photographer, the objects shown on the counter don't align with the reflection in the mirror. A box of tissues can be seen in the mirror reflection, but no box of tissues can be seen on the counter. There is a makeup box and a blue bottle with a white top shown on the counter that are both reflected in the mirror, but the box of tissues reflected in the mirror cannot be seen on the counter.

Revealing mistake: Whilst Mima is crying in her apartment after filming the rape scene, she throws her duvet cover across the room. When the duvet lands on the ground, the part of the duvet positioned in the bottom right corner of the bed can be seen unnaturally sticking upwards and not lying against the bed or the floor like the rest of the duvet. (00:36:57)
Revealing mistake: When Mima sees the train passing by outside the window, a white shirt can be seen hanging onto a wardrobe door in the reflection of the window. We are then shown a shot in front of Mima walking away from the window and the shirt hanging onto the wardrobe is now black. (01:09:42)
Revealing mistake: When Mima is first shown being attacked by the stalker, in the shot where the stalker says "Like anyone can hear you right now", we can see that the two of them are drawn without faces. (01:04:13)
Suggested correction: This isn't an error, just a common stylistic choice in a lot of animated films.
Revealing mistake: Just after Mima is questioned by the reporters about the murders of the screenwriter and the photographer, the scene cuts to an overview shot of a set inside a studio. In the shot, many of the people on the set are drawn without faces. (00:59:13)
Revealing mistake: When the screenwriter hears the music playing, there is a wide shot of the parking lot he is in. In the shot, many of the number plates on the cars do not have any numbers or letters drawn onto them. There is a white car beside the elevator that has a very faint M and the start of another letter beside it, but is incomplete. And the number plates on the cars facing opposite the screenwriter do not have any numbers or letters at all. (00:41:47)
Revealing mistake: Whilst they are filming the rape scene, after the director yells cut, he tells the actor playing the rapist to do it faster. The actor who plays the rapist then lifts his head and apologises, and we can see that he has been drawn without a face. (00:33:34)
Revealing mistake: When Mima begins performing her final song at the CHAM concert, there is a shot of three audience members at the front talking with one another. In the shot, the stalker character walks into frame. In the first few frames when he first appears, there are two drops of blood on the right hand side of his face. But these drops of blood were not drawn into every single frame of the shot, as they pop off his face mid-way through the shot. (00:08:07)
Revealing mistake: Whilst Rumi is speaking with the producer about Mima, a man comes into the room to talk about how the new CHAM is coming along. When the man stops walking to take out a magazine and places it on the table, it can be noticed that, due to an animation error, his legs pass in front of a coffee cup on the table. (00:24:18)
Revealing mistake: When the fashion show on the television show is being shown, members of the audience are shown taking photographs on their cameras, but their hands don't move. They are never shown pressing the button on the cameras to take the photo, but the photos seem to get taken anyway. (00:22:46)
Revealing mistake: When they are filming the TV show, whenever a monitor or television on the set showing what the cameras are filming is shown, the characters shown on it are standing completely still and motionless. The animators likely only drew a still image to show on the monitors and television without drawing any character movements. (00:14:21)
Revealing mistake: Mima is having a conversation with her mother whilst sitting on the floor with her knees bent and shown positioned on the floor. There are frames during the conversation where we can see her knees passing over the edge of the table next to her. (00:11:32)
Revealing mistake: Whilst Mima is opening the letters, there is a shot where she is sitting on her bed in the foreground of shot, and the TV is playing in the background of shot. On the shelf below the television is a game console with two controllers on top of it. The animation for the controller on the right is very weird. The right side is drawn longer than the left side, and its positioning on top of the console makes it appear as if it is hovering above it. (00:10:47)
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)
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)
