Mayuki is advertising Pentax cameras again. Once again, the videos were taken by Sonoe. Yes, this time it’s videos, because the camera in question has video built in. The video is also embedded in this entry, but the one on the Pentax site seems to be better quality, if a little slow to download and thus a bit choppy on playback. I’m afraid I appear in a few scenes; try not to let it upset you too much. The videos were taken a few weeks ago, so they’re not too far from what Mayuki is like right now.
In the scene with the spoon, when she taps her cheek, she’s using the Baby Sign for “tasty!”. I think she was eating creme caramel at that point, which would explain it.
