In the "Bed at the Classroom" scene, Futaba holds the Poemi's left hand while they are on the bed, but in a close-up shot the hand that Futaba is holding looks like the hand of an adult woman, then in the next shot, she is holding the small Poemi's hand.
The Puni Puni Poemi has a tattoo on her left arm that disappears and reappears between shots.
Many of the Poemi's fast-spoken lines do not match her lip movements. For example, in the first episode while the Poemi is downing from a rainbow, she says a line, but her lips do not move.
