I love how the stance changes every year. In the first, Sato seems lost, and faces more to the left of the viewer. In the second, he has a more exploratory pose, and directly faces the viewer. In the third, he looks confident, as though he's been here many times, and he faces far to the right of the viewer. In the last, he still faces the same direction, but his posture is challenging and cautious, ready to face some threat unseen to the viewer. The storytelling changes are excellent, and I absolutely adore it~
