A Day in the Life of Retsuko - S1-E1
Continuity mistake: When Ton plops Tsunoda's books into Retsuko's hands, the top book is well above eye level to her face and about to the white spots above her eyes. When it cuts to a closer shot, suddenly they are down lower and level with her mouth.
A Day in the Life of Retsuko - S1-E1
Continuity mistake: After Ton bashes Retsuko for not getting her tea right, she sings some death metal in the bathroom before joining Fenneko back at the computers and they start talking. Between them is a pink cup with some orange scissors, and an assortment of writing utensils. They are fanned out, but show that the red one is closed to Retsuko with the black in the middle and the yellow closer to Fenneko. When the camera changes angles to show them both sitting there, this order of pens is flipped, with the scissors still being in the same spot.
